Timber Box Sash Windows

Many of our customers prefer the look and feel of traditional timber framed box sash windows and we have a wide range of timber frames to choose from. Timber framed windows can still contain double or triple glazed glass to ensure sound and heat insulation but offer that classic, heritage feel. Our frames come in a choice of engineered hardwood or Scandinavian slow grown pine, to ensure strength and durability. The windows benefit from A-rated argon gas filled glazing and neoprene seals to all joins, eliminating cold and draughts. Our products come factory sprayed with micro-porous paint; because of this we are able to offer a 10 year guarantee on the paint finish.

PVCU Box Sash Windows

An excellent modern alternative to timber frames are uPVC frames. This provide a long lasting, low maintenance alternative to timber and still look elegant and stylish. Our Heritage windows are designed with all the traditional detailing found in period windows but are made with one of the only PVCU products that has been approved and installed successfully in conservation areas, Sash Window London has a wealth of experience in dealing with these requests.

We only stock the finest quality box sash windows and are committed to ensuring that high quality remains consistent throughout our entire product range & installation process. As registered members of FENSA our windows all have a GGFI 10-year insurance backed guarantee. We are rated as 5 stars on Check-a-Trade and valued by our customers.

Replacing your windows is one of the biggest purchases when improving your property. For peace of mind and value for money you need to ensure your windows will not only look the part, but will stand the test of time. This is why we replace the whole window and frame rather than restoring the existing box.
