Learn About Sash Windows
Sash Windows are much more common in the UK than they used to be, but they are a very beneficial type of window to have. Whether you have box sash windows, timber sash windows, or anything in between, you can’t deny the benefits of these windows. “Sash” actually originated from the word “chassis”, meaning frame in French. They are extremely elegant, and the history of sash windows includes places like Hampton court palace, Chatsworth, and Kensington palace, where the sash windows first made their famous appearance in the 17th century.

The popularity of sash windows became solidified when a connection between them and royalty was forged. In today’s world, they are on many period homes with sash windows and also installed into many new ones as well. They are timeless as well as being great in the summer. Since they can be opened from both the top and bottom, they are a great way to cool your house down. Also, who actually enjoys cleaning windows? Not many people, but sash windows allow you to stay inside while you clean them because you can reach all of the window from inside of the room, making it much less of a hassle to clean them.

If you move in somewhere with sash windows and want to change them, it all depends on where you live if you can or cannot replace the sash windows already in your home. If you moved into a conservation area, there are restrictions on how much you can change your property, even the windows. In English heritage, windows and doors made up a big part of the character of a home, so you won’t be able to alter them very much which means if you want to do something like switch from timber sash window windows to UPVC sash windows and you live in a conservation area, you probably won’t be able to make the switch, its important to know that mist commonly properties increase their value with timber sash windows, and enjoy better energy saving with a timber frame.

Whether you pick box sash windows, timber casement windows, or your sash windows double glazed, or another way, you will absolutely love them. They add an air of regality to any home, whether you want to add them in or already have them. Sash windows are more than just aesthetically pleasing to those who live with them, they are easy to clean, a great way to stay cool in the summer, and will make you feel like royalty. They are a great addition to any home and will definitely help you save money on electricity in the hot months of the year, as well as insulate from the cold with timber frame and doubled glazed.

Sash windows are available in many styles and and sizes and this is not a coincidence, sash windows are mostly used in city town houses helping to keep cool air flowing in the bottom of the window

while hotter air flow out the top, as cities tend to be warmer than urban areas.
The history of cities and its architectural influnce scales back many hundreds of years, not surprisingly. Even today many homes that are refurbished and built the owners and architects like to

vary their style, all this adds up to why almost every home would have unique window measurements. It doesn't stop there as most windows also need to match the architectural style of the building

and design choices. Whatever your building or design choices for your property woodstock joinery have a workshop for building bespoke joinery and box sash windows.

When you hear sash windows or even see one, you think oh that's a window that slides open from the top or the bottom and that's it, however they are far more than just one style of sash window, there are curved tops, different styles of glazing bars, as well as different types of glazing and we didn't even get to the varying size of frame, sash mechanisms and window furniture.

I would go so far as to say that no two houses are exactly the same, so many houses are built in different era's in London with different window sizes and frames. Its not surprising that windows need to be made to measure. The glass choices on their own when matched with glazing bar configurations can leave you with a dizzying level of choice to make.

Its important that a professional joinery manufacturer is chosen to make your wooden box sash windows, the timber choice is also such an important part of the craft of the sash window, it can determine the life of the window.

A sash window is not going to last if it is not installed professionally so there are no gaps to allow water ingress, as well as a professional job of the painting and finishing, making sure to keep it maintained will also be important if you want to maximise the life of the window.

When asked to make a sash window there's an important process to follow,
the selection of materials used will determine the longevity of the window,
the reliability of opening and closing sashes is as important.
maintenance is also an important part and should not be neglected, let us
not forget that the investment will be wasted if you do not take care of your
of your sash windows.

Sash windows Should be made from hardwood so the frame minmises any weather
effects that could make it warp and twist. With the correct design and materials
used you can be sure of a long lasting window that you can feel good about.
No window will ever be worth having if it does not insulate you from the weather
and noise from outside, always choose double glazing units that have argon gas
to reduce the thermal transfer of heat or cold to keep your home temperature
just right.
Once your window is made with the correct weights and pulleys you need to ensure you
have high quality catches to ensure a secure fastening of the window for security.

The final stage for any sash window is to install in the London place of residence
or business as with many properties we may be replacing all or matching an existing window
the design, and painted finish should match the style and architecture of the building
and if required the existing windows of the property.

Not all sash windows are made the same, over the years there have been many advancements not all of them are good though, for example while energy saving and functional upvc sash windows are not the high quality craftsman ship you would expect from hand made wooden sash windows. 

The Good really should be the excellent as the quality of hard wood box sash windows being produced is really something to be quite proud of, for many homes these quality windows improve the value of the home as well as improving the energy saving with the new draught excluding properties of the window and the low E Glass that reduces the cold transmitting through the glass.

Along with the superb finish of hand made windows and the high class window furniture to bring you a window you'll be proud to have in your home.

The Bad has to be the original windows now replaced with UPVC it would be a real shame to degrade a property with these new plastic imitations of the true sash window.

The Ugly for many an original sash window could be a thing of beauty, although for too many homes still in London the neglected sash window has single glazing flaking pain and gaps that cause heat to escape, now that's an ugly situation in need of repair or replacement.

The photos attached are examples of custom hand made wooden sash windows.

So there you have it The Good the Bad and the Ugly of Sash Windows.

There are many things that modern sash windows now do that save energy over the traditional single glazed sash window.

Double glazing and argon gas creates a barrier against the cold by reducing the thermal conductivity as compared to normal air.

There is Special glass called Low 'E' glass this keeps in heat in much more than normal glass, in addition there is a warm edge spacer bar between the glass along the edges this helps the internal glass to stay warm and lower thermal transmittance.

draft excluding strips - reduce and practically eliminate any draft between sashes this along with hard wood frame and sashes correctly installed with double glazed units can have a dramtic cost saving on your energy bill.

There is an unforeseen benefit to double glazing which in central London can be very welcome and that is the double glazing reduce traffic and external noise, achieving a decibel rating of 42db.

If having your sash windows updated to include the draft proofing system and low E glass glazed units. then the next best thing would be secondary glazing or thick curtains that will keep heat in but not nearly as much as properly made and fitted sash windows.

Various styles of sash windows

Most sash windows are made to measure, as with most properties in london they are unique and the windows should match the existing.

This said there are distinct types of sash windows

Georgian Era 1720 - 1840
Normally six over 6 panes traditionally with one sash fixed.
this would have meant 6 panes of glass in the top and bottom sashes.
these are now made with both sashes moving, and double glazed units with glazing bars placed on top.
here are some examples.

Victorian Era 1830 - 1910
traditionally 6 or 4 panes of glass used in designs with both sashes moving. As the cost of glass manufacture dropped the panes of glass got bigger. Both sashes operate in Victorian sash windows.
we supply these double glazed with glazing bars.
here are some examples.

Edwardian Era 1901 - 1919
Typically this has no glazing bars in the lower sash, to allow more light to pass into the room, this was the fashionable style of sash window in the Edwardian era. Having large panes of glass was expensive and a sign of afflence during that time.
both sashes do move in this design.
we supply these double glazed with glazing bars.
here are some examples.

All sash windows and frames are made to measure to match your existing design or meet your choice for a new build or rennovation project, call to discuss your design and build requirements.

A sash window or hung sash window is made of one or more movable panels or "sashes" that form a frame to hold panes of glass, which are often separated from other panes (or "lights") by narrow muntins. Although any window with this style of glazing is technically "a sash", the term is used almost exclusively to refer to windows where the glazed panels are opened by sliding vertically, or horizontally in a style known as a "Yorkshire light", sliding sash, or sash and case (so called because the weights are concealed in a box case). The oldest surviving examples of sash windows were installed in England in the 1670s.
