Sliding sash windows have a timeless appeal and are ideal for period properties as well as traditional style newer homes. Featuring a choice of beautiful sash horns, astragal bars and elegant hardware, our sash windows offer ultra high performance on a par with the best casement windows thanks to our patented sash seal.
Our range of historic box sash windows is designed to satisfy planners with the option of single or slimline double glazing, various design options and our smooth cord and sash window pulley system for absolute authenticity.If you don’t have to adhere to strict planning rules but still wish to incorporate the charm and character of a sliding sash window, you can opt for our spiral balance system which is ideal if you have a narrower window opening or are looking for a more cost effective option. This product is well suited to modern construction methods and buildings.
We also offer the Tilting Spiral Balance design which enables the window to tilt inwards to allow cleaning from the inside.These are great for those hard to reach windows.
I Love the fact that my windows were made in Britain. They are beautiful and do a fantastic job, the house is transformed.
With a choice of window layouts – square bay, angled bay, bow, Bay Windows arch top, internal arch and arch fillet options, all of our sliding sash window designs allow for high levels of customisation.
Whether you are an architect or a developer considering converting a former Georgian mansion that requires a retained facade or a homeowner looking to replace your own period property sash windows, we have the perfect solution. If the traditional sash window does not meet your needs, we also offer the Yorkshire Sash, (horizontal sash window). Whichever option you go for, our attention to detail is second to none.
