Sash Windows Logo

Dedicated to the manufacture of innovative sash windows

Using our exclusive, chamfered, putty line sashes and external bar our Authentic Collection is an excellent yet competitively priced, trade window. Designed to replicate the style of timber sash windows, it is available in a range of wood foils and finishes, but not as detailed as our Vintage Collection.
