If you are looking for a traditional sash window renovation expert, then look no further than the Chameleon windows restoration and decoration. Our timber window experts have provided quality sash window renovation services for over 15 years and have a wealth of experience in the field.
Our company offers a broad range of sash windows renovation services, including:
Original Georgian sash windows look fantastic but can be very draughty and energy inefficient due to single glazing. You might want to think about installing secondary glazing or replacing your old windows with a new double-glazed sash window but don’t before you look at our sash window double glazing service.
The original timber sash windows can now be retrofitted with slim-profile, heritage double glazing units without any modification to the original sashes – and all without compromising on authentic sash window appearance.
Our traditional sash window double glazing service is a cost-effective way of improving your traditional windows’ energy efficiency and reducing outside noise, as well as improving security. With enhanced security features, we ensure your windows meet modern security standards.
We specialise in the renovation and double glazing of all types of traditional timber windows – including box sash windows, horizontal sliding windows, and vertical sliding windows, Edwardian windows, and French windows. We also provide a range of services for traditional doors, such as French doors, wooden doors with glazed panes, and more.
We use vacuum double glazing, a triple glazing alternative, as both glazing units have the same U-Value of 0.7 W/m²K, but one is 32 mm, and the second one is only 7 mm thick. This is a perfect choice for traditional windows as it provides the same thermal efficiency as triple-glazed windows but retains the original character and authentic appearance of your home.
Our sash window double glazing is an alternative to replacement and secondary glazing. It offers better thermal performance and acoustic insulation than secondary glazing and some modern wooden windows.
This ensures your period windows retain their traditional charm and authentic sash window appearance while improving their modern performance.
As well as double glazing and timber frame renovation, we also offer a draught-proofing service for traditional timber windows, which is an effective way to reduce rattling and draughts.
Our expert team usually combines draught proofing with our double glazing retrofitting service, providing the best results.
The benefits of draught-proofing your windows include:
If you live in a listed property or conservation area, you might be concerned about changing your original windows. However, our expert craftsmen have extensive experience working on listed properties and conservation areas. We offer expert advice on the best approach to your sash window renovation project while maintaining the aesthetic appeal of your authentic sash windows.
We provide a range of sash window renovation services for listed properties and conservation areas that comply with current regulations and do not require listed building permission.
You only need to contact the conservation officer and submit a listed building application form if you want to retrofit vacuum double glazing into your original window frames, as this is considered a ‘material change’.
Otherwise, our other timber sash window renovation services, such as draught-proofing and timber frame repairs, do not require any listed building permission as they are ‘like-for-like’ replacements.
We also support our clients with paperwork when they submit the listed building application form for permission to install double glazing. This application is usually supported with examples of completed projects to prove that window style and original designs remain unaltered, retaining the classic aesthetic of your property.
Bespoke timber sash or casement windows are generally made of wood, which is more expensive than other materials like UPVC or aluminium. Secondly, sash windows are often made to order rather than mass-produced in a factory.
There are a few things you can do to make your sash windows more efficient: Install Secondary Glazing or retrofit vacuum double glazing into existing sashes and install draught-proofing to seal any gaps and prevent draughts. You could also get your sash window frames refurbished if they are in a poor state.
The average lifespan of a wooden sash window is around 30-40 years. Of course, this depends on a number of factors such as the quality of the timber, the level of maintenance and the environment in which the window is situated. A well-maintained sash window should last for many decades.
