Proposed invention title: New Window and Door Extension System (NWDES)


If windows glazed with panes of glass in a single layer are regarded as the basic, most common window type, then double glazing can be regarded as an accessory for the basic window. Shutters can be regarded as an accessory for the basic window. Often, shutters are decorative, non-functional, but shutters can provide advantages in some circumstances. For example, like double glazing, they can improve insulation for the building, or part of the building. External shutters have the disadvantage that they are subject to weathering and must be maintained at intervals and sometimes replaced. The components used in this invention are internal, not nearly as vulnerable to weathering and needing practically no maintenance.

However, the benefits of these and other accessories, which include 'storm windows,' are limited to a marked extent. Double glazed windows offer substantial improvements in the reduction of heat loss from the room but the improvements are restricted in scope. Existing window accessories are not only restricted in scope but inflexible to a large extent, offering limited opportunity, or no opportunity at all, to react to environmental changes - diurnal changes, seasonal changes, annual changes, the longer term changes which constitute the challenges of climate change.

The New Window Accessory System offers far reaching improvements in flexibility and offers the possibility of very substantial improvements in reacting to environmental changes, such as the very great differences between summer and winter conditions in large areas of the United States, as in many other countries.

Already, I have constructed a working prototype of the invention, which is already demonstrating its advantages.

The form of the invention described here in some detail makes use of an accessory unit, the components of which are listed and described below. If the base of the window is at floor level, the unit rests upon the floor. Otherwise, the unit rests on a support. Suitable supports are often readily available. In the prototype version described here, an existing support was available, a storage unit which I constructed next to a window and below the window.

Summary of the invention

Two versions of the basic invention are available, the track version and the hinged version. The track version has substantial advantages over the hinged version and is the form described in detail here.

In the hinged version, the components move in the manner of hinged shutters on the outside of a window, except that the hinged components are inside the room.

In the track version, a carrier in the resting position is outside the window zone but can be moved within the window zone, in which position it can be used to give the advantageous changes  described below. The carrier runs on a simple track and carries one or more (typically more) boards or other components, collectively referred to as the accessory-layers or simply layers.  It is the accessory- layers which provide the basic functionality of the invention and provide so many opportunities for changes to the system which offer wide-ranging advantages.

Here, I describe a single carrier-layer system, which in the resting position occupies one place, to the left or right of the window. Another possibility is the split carrier-layer system, which in the resting position occupies two places, to the left and right of the system. When the two halves of the split carrier-layer system are moved together, the result is to produce a unit which is very similar to the single carrier-layer system. The appearance is almost identical and the advantages are the same.

If the carrier is viewed as a kind of movable transporting system (a kind of miniature railway / railroad), the track is the component on which the carrier rests and along which it can move. In the description here, the track is a simple wooden  U-channel. There are two castors towards the ends of the carrier and these castors run within the broad groove in the U-channel.


Where support for the track and the other equipment is needed, I can make use of various techniques to ensure the necessary strength, such as wooden components used with steel bars, which may be perforated for relative lightness, and sthe use of  substantial wood sections, in particular, sections of wooden 'sleepers' of hardwood or lighter softwood.

The bases of the accessory-layers fit in the groove of the U-channel, making a kind of vertical 'sandwich' (if there are more than one or two layers.) The diameter of this particular U-channel is fixed but not all the space may be occupied. U-chanels with adjustable diameters can be made. Wedges or simple gripping mechanisms can be used to allow for unoccupied space in the U-channel.

In the version described in some detail here, with accompanying images  there is a layer which has central importance in this invention, made up of two sub-layers. Wood offers many benefits for the construction of this layer but other materials may be chosen instead. In this case, one sub-layer is made up of oak panels, each of them very near to 20cm wide and 90cm long, with tongue and groove edges, so that they fit together closely in a vertical position. This layer is on the inner position.

The panels have aesthetic strength (although the panels used here are not varnished and were previously used in outdoors conditions).  A material with no aesthetic benefits is used for the position nearer to the window glass, OSB (Oriented Strand Board.) This is a basic configuration, which does allow for additions which add significant functionality (and enhanced aesthetic benefits.)


Implementations of the basic system may take very different forms. These may be  predominantly 'traditional,' making use of oak panelling, although it has ] more contemporary additions, the metal strips an the side of the panelling which are used for support of shelving. The system can accommodate a very wide range of tastes and preferences with a very great degree of flexibility. Layers could be used for the position nearest the viewer or viewers inside the room which include, to give just a few examples, painted or plastered panels. These could match or contrast with the decor of the room, in a very wide range of colours and textures. It would be possible to make or obtain plain surfaces which users could treat themselves with paint, plaster or other materials, if they wished.


In the next section, I provide further information on these benefits and the many benefits to be obtained by adding further layers.

Detailed description

A rigid layer is a necessary component of whatever layers are transported in the carrier. In the prototype, the rigid layer is made up of the two sub-layers constructed with oak and OSB board. This is a list of additional, 'optional' layers which extend the functionality of the invention to such a significant extent - as I would claim. The choice of these additional layers is governed by such factors as changes in external conditions, personal preferences and by the compatibility of components.

The two different materials in the sub-layers, oak and OSB, have advantages as insulating materials but there is a wide choice of other materials which will significantly enhance the insulating value of the accessory. Most, but not all, are available in board form. Materials not available in board form can be enclosed in containers suitable for insertion. The insulation layers include ones constituted of polyurethane and other synthetic insulating materials, sheep's wool and insulating materials derived from plant sources.

Double glazing relies upon panes of glass enclosing trapped air (or an inert gas such as argon.) Double glazing has obvious insulation value but other forms of insulation can be more efficient, a factor important for buildings with severe or extreme environmental conditions in winter.

When the weather is warmer, perhaps much warmer, then the higher degree of insulation is not needed. This system allows for the insulation to be removed, or to be replaced if conditions become much colder. It is easy to replace it, if wished,  simply to retain heat within the room / the building when night falls and the temperature falls.

In cold weather conditions, absorption of any solar radiation which would be beneficial is an obvious advantage. This absorption can be increased by placing a dark panel in front of the layer or layers making up the basic layer.

In hot conditions, reflection of incident radiation becomes the priority. Inclusion of a white, reflecting panel in the layer collection is very easy to achieve. As with the dark heat-absorbing layer, the layer can be left in place for a long or short period of time.

The windows of a boarded-up building are sometimes a sign that the building is a neglected one. Boards can have high aesthetic value and the boards which can be used in this system, visible from the outside, can have this value, for example, planed, varnished boards.

However, there are many other possibilities. In this prototype, there is contrast between the light OSB boards, which do not cover all the visible window space, and the darker oak boards. The contrast can be viewed from outside the building. Interesting patterns can be formed, taking advantage of contrasts of colour, texture and so on.

Boards can also be incorporated which are useful and informative, at least to the owner, such as the signs 'House to let,' 'House to rent,' 'Apartment for sale.'

Security is a matter which is very important, obviously in some areas rather than others or at some times rather than others. Windows at ground level are obviously particularly vulnerable to burglary and other risks. Many local and national politicians report that the security of their homes and offices is a matter which concerns them greatly, although this is a  problem which has more general significance for democratic societies.

Video recording cameras, and not only very slim cameras, could be incorporated into the system. These cameras could be protected from damage far more easily than many of the cameras often used for security purposes and other purposes. I have no such cameras of my own, have never made use of them and have no intention of using them but I would want to further beneficial use of these video recording cameras, for such users as those who live with the threat of terrorist action or in dangerous neighbourhoods. 

Beneficial applications may be used in non-beneficial ways. It is conceivable that in some repressive countries, cameras could be used for repressive surveillance, not the kind of surveillance which is sometimes needed in democracies, to
  give information about terrorists and others. This might add to difficulties as well as lessen difficulties, but the situation as it already exists is this kind of situation, and video recording cameras aren't in the least a novelty. It would be impossible to do even partial justice to these complex issues here

There are external risks and internal risks. The risk of fire can arise from external or internal origins. Specialist fire resistant panels can be inserted into the system, as an outermost layer. Escape from fires which arise from inside the building would sometimes be easier if escape from a window were possible. Smashing window glass may be needed for escape to be possible.

A radical version of this system, which would offer other advantages besides fire safety: the existing window to have glass removed and a glass pane, or glass panes, forming the outer layer. In this case, the unit would be located all the time or most of the time in the window space, not outside it and moved into the window area as needed. An advantage - the ready opening up of the window space in hot weather so that there is the least possible barrier to airflow. When glazed panels are used in this system, they can be readily removed and readily replaced.

This would not be beneficial in hot climate conditions when the outside air is at a higher temperature than the air inside the room. However, at night, when the outside temperature is lower, then it would be beneficial, at least in rooms which are above ground level. Security considerations would make open entry points inadvisable  at ground level, unless the security of the surroundings could be guaranteed. Wire mesh panels - where the wire is strong - can readily be inserted into the system. When the window remains glazed, wire mesh panels can be beneficial to prevent theft, for example, the windows of ground-floor workshops. The tools and equipment can be seen form outside (unless privacy glass is used, with the right environmental conditions for it to work) but the wire mesh can act as a deterrent.

In this system, the basic layer, in this case of wood, offers a high degree of protection but a strong security layer can be inserted, obviously, nearest to the window glass, which reduces the risks further.

A layer of one-way privacy glass can easily be inserted, so that occupants of a room can see the exterior but the interior space is not visible from the outside. This form of glass only works if light intensity is greater outside than inside, but this system allows light intensities to be controlled much more easily so that the privacy glass is effective to a much greater extent.

In a house with windows overlooking a garden - or in houses with no garden at all - then wooden 'diamond lattice' can be an attractive material to use. Lattice of this kind is often used in gardens and a lattice window would enhance appearances in many cases. A diamond lattice also gives a means of securing greater privacy for the occupants of rooms.

Solar panels can form yet another layer. Obviously, a solar panel will form the outermost layer, whatever other layers are used. There are significant advantages as well as disadvantages in the case of this application.  The disadvantages include ones which involve the directionality of sunlight. Window solar panels are very restricted in comparison with panels on roofs. Use in bay windows is more advantageous than use in other forms of windows. Light from various directions can be intercepted.  One advantage, to do with cost, is that the panels are sheltered. It would be possible to produce solar panels which are cheaper for this indoor use. Weatherproofing the panels would be unnecessary.

The rigid, opaque boards which form the basic layer can be used with different dimensions and with different distances between board and interior wall, the wall adjacent to the window.

A board appreciably longer and wider than the window space and with practically no gap between the unit and the wall surrounding the window will effectively exclude all light. This will benefit the sleep patterns of many people, those who live in latitudes where in summer, night falls later and daylight comes earlier than in lower latitudes. This system can ensure dark conditions more effectively than the use of curtains or blinds. The system can easily be used with blinds, blinds can certainly remain in place, but is incompatible with the use of curtains.

However, a degree of light penetration could be welcome. If an opaque layer is used in the system which is not as wide or as long and there is a small gap between layer and wall, the glow of light visible at the outer edges of the board is very attractive.

The layer facing the outside world can be made attractive and sometimes useful. This is also the case with the layer facing the space inside the building.

A few examples, from the prototype. Here, the oak boards are the visible component from inside the room. Framed art works, photographs, posters can be mounted on the boards.

There are strips at the left and right edges of the board layer which allow supports for shelving to be inserted very quickly and easily. Obviously, the shelves can be used for storage of a very wide range of articles. They may be bookshelves, shelves for storage of domestic essentials, fruit and vegetable produce ...


Seals, which reduce heat loss, may have a large gap inside the peripheral sections. Seals can also be used which have material throughout. Seals can be incorporated into the 'repertoire' of layers which are inserted into the carrier. So too can glazed units, a form of moveable window glass.

By using a glazed unit in the carrier, moved into the window space, a single glazed window can very easily become a double glazed window and a double glazed window can become a triple glazed window. A window space can be entirely unglazed. This can have benefits in certain circumstances.

For example, during long, intense heat waves, a window with no glass can give the maximum airflow into a room and other parts of a building - but not during the day, when air from outside is likely to be hotter than air inside the room. The changes can be made easily - a window with glass in the heat of the day, a window without glass at night, for relief from the  heat. Openings in windows are more often than not of insufficient size to cope with the demands of hot climates or hot conditions in temporate climates.

At times when maximum air flow would be beneficial, a window which allows and promotes maximum air flow is beneficial - best of all is a window which (temporarily) has no glass at all.

Environmental benefits can be difficult to achieve, and sometimes environmental benefits are accompanied by unexpected disadvantages, as I see it, but I think that this invention has genuine environmental benefits without any disadvantages that I can detect. A reduction in the energy demands of air conditioning units would be very beneficial and I think that this invention would have beneficial results in this respect, and not only in this respect. The benefits as regards insulation and the associated reductions in energy use are another example.

Doors raise many of the same issues as windows. Present door design, like present window design, often concentrates attention on the door as multi-functional component, one which achieves a degree of success in meeting the demands of functionality but which could achieve more.

Doors often have glass panels, but a door which admitted much more light would often be very advantageous, for the comfort of the people living or working there and for their sense of well-being - a door which enhanced the effect of the windows, if the window design is a good one.

The insulation value of doors is well understood now but insulation of doors is probably not, in general, treated with the same level of care as the insulation of windows.  A system similar to the window system proposed here, hinged or sliding, would offer many advantages and be much more flexible and  much more versatile, including the enhancement of the insulation provided by doors.

Doors offer particular opportunities for external fittings, so that changes can be made from outside, but many of the fittings can be internal, as in the case of windows. The necessary detail is not provided in this particular document. Sliding doors are much more convenient than hinged doors for adding suitable extensions. When a sliding door is moved from the door-space to the adjoining wall, the opening can be used for a variety of useful purposes, such as air-drying - air-drying of clothing or other fabrics after washing, hung on a suitable rack, air drying of fruit and vegetables, on suitable surfaces, and even air-drying of 'green' wood (with a high moisture content.) These applications eliminate or reduce the need for air warmed by the use of electrical energy, with obvious environmental benefits.

The first two of these applications, drying washing and drying fruit and vegetables, are easy to apply. In the case of timber, there are practical difficulties. In many or most cases, kiln drying will be necessary. The timber is bulky, of course. Only large doors (and windows) of farm and factory buildings or in some cases workshops will be suitable. The timber has to be left in place for a long time, a year or more in most cases. The moisture content of the timber will not be less than the environmental moisture content - in general, the timber will not be suitable for indoor use but will be very suitable for external use.

These considerations apply to the use of windows as well as doors. Windows are suitable for installing extensions for the air-drying of clothing and other fabrics after washing and the air-drying of smaller quantities of fruit and vegetables but not at all for the air-drying of timber.


If the carrier, castors (or wheels) and track, with the components which are stored and moved when necessary constitute the basic window (or door) extension, then a racks, drying surface, timber support structure can be regarded as constituting an 'extension to an extension.' For the purposes of this account, I name the basic extension  'extension 1' and the extension to the extension 'extension 2.'

Extension 2 may be physically connected to extension 1 or not connected but in close proximity. For example, it would be possible for extension 1 to be stored - that is, in the 'resting position' to the left of a door or window and extension 2 to be stored to the right of a window, or vice-versa.

Alternatively the two kinds of extension can be used independently. Extension 2 may be mounted on a carrier, which runs on a track but in most cases the width of the extension will necessitate a twin-carrier, twin-track system. A folding clothes rack can be supported by a single carrier but in the open position, two carriers would be needed. Alternatively, provision can be made on a surface,  of suitable height in the case of a window with a base above floor level, for safe and suitable support.


As with all applications which are near to windows, it is essential to install safety barriers for temporary or long-term use. A strong wire mesh panel fixed fixed so as to cover the window space is one method. Another is to install a sheet of strong non-vitreous, shatterproof material to cover the window space.


Commercial applications are many and varied. The architectural applications are intended to promote flexible working. The possible configurations of the system can be many and varied, giving very substantial advantages in a wide range of working environments, including offices, workshops, factories, farm buildings. A brief summary of some uses:


The system gives versatile storage space, on open shelving and in units with doors. The storage areas can be small or tall, from floor to ceiling.

The storage space is readily moveable, since the carriers can move.  Long track  items on shelves / in cupboards of units can be moved from desk to desk  or from workbench to workbench. The units can be used in a workflow  assembly line. 

Shelving and other units can be positioned in relation to desks /workbenches for optimum use. If the desks or workbenches are moved or reconfigured, the units can easily be moved.

small workstation with eg desk / small workbench and chair can be moved itself from place to place, positioned and repositioned.

blackboard / whiteboard

The units which can be readily moved can comprise Dexion shelving, filing cabinets, blackboards and whiteboards, printed notices / information - information in a form which often has advantages over online information. For example, important safety information can be visible at all times. 

Moving objects will often have advantages over alternative methods, such as the use of trolleys. Carriers can occupy space otherwise unused.


Photographs and other image material to the left: comments

This shows the window area of the small room before the prototype of the invention was set up - long before the idea of the invention came to me.


This shows the part of the small room where I have constructed the prototype of the invention. The prototype is already finished and in use, but not for the full range of applications. The room is North facing and the window is single-glazed, not double glazed. The window is equipped with blinds, but these were not pulled down  at the time. Just visible, towards the bottom edge of this photograph, is a very thick  beechwood board. The top board, near to the bottom edge of the window, is made of thin plywood. These boards, everything seen in the photograph, were put there long before the idea of the invention came to me - which was a week ago - but the strength of the beechwood board is now an important factor in supporting the invention prototype. A wooden pillar, not visible in the photograph, enables the plywood board to support the prototype without any difficulty. This shows the prototype in the 'resting' position - the position before the unit is moved to the left, into the window space.

The prototype has been moved from the resting position to the window space. Some parts of the prototype are hidden but part of the carrier is visible, the ribbed wood which makes up the rectangular structure, although the castors and the track on which the unit can move are not shown in this photograph or any of the other photographs. Visible here, on the right, are the oak boards which constitute the inner layer of the unit, the boards arranged vertically, and also two shelves which are held by supports inserted into strips at the edges of the boards.  Photograph 8.jpg shows the shelving more clearly. 


This shows the unit in the same position, in the window space.  Moving the unit takes hardly any effort. Visible in this photograph and the others which show the unit is, high up, the cylindrical safety barrier which prevents the unit from toppling forward. The safety device has a suitable safety rating and runs the entire width of the wall. It is screwed to the wall at the ends. The panelling of the walls of the room has been placed horizontally and it will be seen that the boards of the unit are vertical. I used boards for the unit which I happened to have available. They had been used for years outdoors and were not cleaned up or varnished before their use here. At the left and right side of the unit are vertical strips, with a series of slits. There are projections on the supports which fit into these spaces. Boards sawn to length are placed on these supports as shelving and of course, the system offers a high degree of  flexibility - more shelves can be installed and the shelves can be placed in a wide range of positions. It goes without saying that the shelving can be used for a very large number of purposes - storage of fruit, vegetables and other foodstuffs, light kitchen equipment or other equipment, as bookshelves, to name a few. The long wooden structure of darker hue which can be seen along the lower part of this photograph and in other photographs has no relevance to the invention. It has been in this position for quite some time and I decided to retain it. 




There are other ways of modifying the plain boards besides adding shelving. The boards can be used to display framed (or unframed) photographs or art-work. Here, I've put against the boards some framed images I have, with no attempt to display them as they would be displayed if they were to be there for some time.




Not a photograph but an image which shows a use for the system with far reaching benefits for  for the use of space in a very wide range of settings, including small and large offices and the homes of individual computer users - mounting a computer monitor on the board. The board may be static or part of the movable system described here. In the image, the computer is fixed directly to the board. Much greater flexibility can be achieved by mounting the screen on a simple support system which is fixed to the board. The support system will have a sliding support which allows the height of the monitor to be adjusted to allow for personal preference and the needs of different users.


This degree of flexibility is usually not possible in established systems where the monitor is placed on a computer desk. There are further advantages to do with security. A computer monitor on a desk may be more vulnerable than a monitor which is wall-mounted. The desk computer may even be moved accidentally to the side of the desk and fall. Another aspect of security - this wall-mounted position allows computer monitors to be protected from theft by strong but simple protection devices, such as lockable boxes or bars.


The shelving system described above can be used to provide desk space below the computer monitor. I describe use of  the shelving system for this purpose but usually, it will be more convenient to have an office desk (or the workstation equivalent of an office desk) for this purpose.


For very compact implementations, the shelf system can have advantages.


Only one shelf may project from the board and it may be large enough to be usable.  The area available is modifiable. A shelf with a larger or smaller area can be chosen, depending upon needs and preferences. The computer and computer monitor can be placed on the shelf, with room at the front of the shelf for a keyboard. Alternatively, two or more shelves could be used. For example, the top shelf could be used for the monitor, the shelf below that for  the keyboard and for general work space and the lowest shelf for the computer itself. 


In the case of long boards, it may well be possible to place the shelving at a convenient height with the support for the shelving fastened directly to the board. If not, a sliding, adjustable support system can be used which will allow the shelving to be at a convenient height.


In the system described, the computer users will have their backs to the wider office (or other) space, but other arrangements are possible. The support for the monitor can be hinged. When it is swung out, the monitor is now at right angles to the plane of the board. The computer user will then be able to use the computer, or carry out work on the materials on the desk, without facing towards the wall / window area.


In offices or other work places with glazing which could be regarded as superfluous, then window space can be 'taken out of commission,' much of the window space becoming opaque wall space and used for the purposes described here.




Dual monitors have many advantages and can easily be implemented in this system, as can multiple monitors amounting to more than two. Multiple monitors are difficult to implement on office desks and in very many workstations. They take up a great deal of desk space and there is only a clear view of a monitor when one monitor is used. Second, third or fourth monitors must obviously be at a greater distance. In this system, a movable board on castors allows different monitors to be quickly moved to the most convenient viewing position. 


The page


mentions a 'logistical concern,' the fact that '

A second monitor takes up additional real estate on a desk, which may not always be available or desirable in close quarters.' This system addresses this disadvantage.


Amongst the advantages is this,


'Using a second monitor makes it far easier and faster to use multiple programs simultaneously. Instead of having to switch between full-screen windows, the second program can be put on the second monitor, making for fewer clicks and faster workflow. This is especially useful in fast-paced work environment where prompt email replies are needed -- an email client can be kept open and available at all times for rapid communication.'


The page includes this comment,

'Increases in productivity are often touted as the main advantage to running a multi-monitor setup ... A 2012 study originally published in the Proceedings of the Human Factors and Ergonomic Society found that dual monitors were measurably more efficient and less frustrating than a single monitor. Additionally, 98 percent of the participants chose a dual monitor configuration as their preference.',




The photograph shows a pedestrian tunnel with fluorescent lighting. This is an example, one of innumerable examples, of course, of artificial lighting with immense benefits, provided by sophisticated technological innovation. Here, natural daylight is excluded and for good reasons.


In buildings, such as offices, artificial lighting has immense benefits too, but wherever possible, use should be made of natural lighting. In this new system, the window areas are places of activities - work and activities other than work. Areas away from the windows can be used to the full. In fact, activity next to the windows and near the windows frees up space in the inner areas. The space can be used in many different ways. It can be used as the three dimensional equivalent of 'negative space,' as used in graphic design. Reduction of clutter in the interior spaces can be a significant advantage.


There are accompanying savings, financial and other - a reduction in spending on electrical supply, a reduction in the resources needed to generate the electricity.

Executive Summary

Illuminating the Ideal Office Environment


The image of a workplace flooded with natural light seems great in theory, but in reality, the amount of light entering a space must be balanced with occupant comfort. When light penetration is uncontrolled, it can cause unwanted glare reflected off of computer screens and uncomfortably hot workstations. When it is controlled by lowering the blinds, on the other hand, it disconnects occupants from a view of the outdoors effectively eliminating the benefit of windows in the first place.


[This new system gives unprecedented control over adverse factors, the means of taking  advantage of the benefits of natural illumination. It addresses the issues raised in the Cornell study with carefully designed components and the techinques needed to use them to the full.]


Key Findings

Employees in environments with optimized daylight and views provided by electrochromic glass windows reported a reduction in physical health symptoms commonly experienced by office workers.

 • 63% fewer headaches

• 56% less drowsiness

• 51% reduced eyestrain


Computer Vision Syndrome

Computer Vision Syndrome is a condition that in this new digital age impacts 70 million workers worldwide. Resulting from prolonged computer use and characterized by symptoms of eyestrain, blurred or double vision, and headaches, it has been shown to be exacerbated by harsh lighting conditions such as glare. Controlling daylight levels in offices while maintaining a view of the outdoors, which allow the eye to refocus and recover from fatigue, can reduce the risk of these symptoms and thereby help employees work comfortably for longer.


Research Methods

To better understand how daylight and views in the workplace impacts employee health and wellness, Dr. Alan Hedge of Cornell University conducted a study of 313 office workers across North America, some of whom worked in offices with conventional windows and blinds and some who worked in offices with View Smart Glass that intelligently optimizes daylight and views to the outdoors.



Employees in workplaces with View Smart Glass reported fewer health symptoms that are commonly experienced by office workers. They reported 63% fewer headaches and 51% reduced eyestrain, symptoms that are commonly associated with glare and suboptimal lighting conditions. Employees also reported 56% less drowsiness, a symptom that is commonly associated with lack of daylight availability as well as uncomfortable thermal conditions.



Providing employees with optimized daylight and views unlocked significant benefits for employee health ...

Above: Layers panels can incorporate solar panels. A small panel in a small window space will only make a small contribution. Much larger panels in much larger window space can make much larger contributions. Buildings with a very large number of windows, larger or smaller, such as modern buildings which are 'more glass than wall,' much more glass than wall, can make a very much larger contribution to the supply of electrical energy.


Hardwick Hall, completed in 1599, used glass on a large scale, giving rise to the local saying, 'Hardwick Hall, more glass than wall.' I don't of course, imagine for one moment that this New Window-Door-Extension-System will ever be applied to Hardwick Hall and that solar panels will ever be fitted to the windows.

The history of window shutters

This isn't a history of window shutters - all I do is give a few, a very few examples of traditional window shutters, simply to make the point that existing window shutters are part of a long and wide-ranging history, both traditional shutters  and contemporary shutters, in many different countries.


In the case of violins, violas and cellos, it's difficult or impossible to improve upon the past. Not so in the very different world of window blinds, I think. Usefulness and practicality are very different from  beauty and attractiveness. I think that in general, in established designs, the shutters are often very attractive, attractive or quite attractive, sometimes useful, more often quite useful.


Some images of traditional shutters



Above, buildings in Dinkelsbühl, now part of Bavaria, Germany. A high proportion of the buildings have shutters.



Above, view of Dinkelsbühl



Above, shutters in Romania. Traditional shutter styles are very, very varied, of course, in colour and design. The shutters I advocate on this page, which are mainly internal shutters, not the external shutters shown above,  can be just as varied.



Above, shutters in Switzerland. The condition of the shutters varies widely, from good to poor - a very different set of values not dependent upon the moral character of the owners or renters. The facade as a whole is obviously in a poor state and needs repair and renovation. The exterior is not in accordance with stereotypes of Swiss neatness.


The interiors of buildings are subject to the same laws as the exteriors, but in different ways and not to the same extent. Exteriors will show the effects of weather and weathering. Otherwise, they begin to show the effects which are shown above. The focus of my attention on this page is the world of interior shutters, and shutters which are solid, not made of horizontal panels - shutters which are much easier to construct and easier to maintain.



Above, houses in Zurich, Switzerland with an air of informality, showing the effects of weathering but not severely.


If a unit is placed in front of an unglazed window-space, with no gap between unit and wall, or the gap bridged with a seal, there's the opportunity to select from a variety of glazing materials as well as a variety of other materials, such as insuling layers and solar panels.


Glazing materials include  the application of single-glazing, double glazing, triple glazing, laminated glass, toughened glass.  The glass may allow views into the property or not, as in the case of glass bricks:
