We are a trade producer of sliding sash windows - indeed we don't make anything else.

Established in June 1988 we've been devoted to manufacturing sash windows since 1991.

We are not a large company; we pride ourselves in producing great products, enabling installers of windows (whoever they may be) to provide products to harmonise with their surroundings and retain the character of the properties they are fitted into.
