Sash window progress

Box sash windows have a special pride of place in Britain. They can be best described as possessing that coveted accolade: the quintessential style of window in the UK.

What makes them special?

In short, they are simple, stylish and elegant. The efficient design makes them economical too. This is also good news when it comes to professional sash window renovation, which is wholeheartedly recommended, rather than destruction; it is less expensive than you think.

Any other style of window, such as casement windows are likely to look out of place in an older building with Georgian, Regency, Edwardian or Victorian architecture.


Conservation has come a long way since those original days of installation. Entire TV series are devoted to the subject; it seems the progress of sash windows will not fade with time. If anything sash window revival is on the increase.

Traditional match

Today, materials are energy efficient yet, remarkably, they are in tune with traditional timber construction; the glazing is also designed to be energy efficient, something the early models lacked.

The sash windows can also be placed directly alongside the original timber sashes and you will barely notice the replacements, so fine is the modern craftsmanship.

Say goodbye to drafts

Draughty, rattling windows are often the first thought of many people when you mention the word ‘sash’. This is far from the case today. With heritage double glazing you can enjoy all the authenticity and history of these lovely windows, stay warm and they can still match and blend in with your older building.

When you consider that the original sash windows were installed nearly 400 years ago, this isn’t a bad feat to achieve.
