    Heritage Windows

    Authentic designs that are hand-built with joints
    that mimic original mortise and tenon looks

What are Timberlook Windows and Doors?

Timberlook is a uPVC window and door system that successfully replicates traditional aesthetics. It is ideal for period or historic projects, and can be accepted in conservation areas by local planning authorities. Our flush sash windows are just as suitable for modern living, as they are maintenance-free and energy-efficient. Timberlook can be specified to Document Q, and is certified to PAS24 with uprated glass and hardware.

The flush exterior finish, with square mortise & tenon looks, mimic heritage casement designs. Timberlook has a refined full ovolo internal decoration, with all the elegance that you would expect. Modern technologies combined with traditional looks.

Sophistication and versatility make Timberlook an ideal choice for any home or building, and we would love the opportunity to discuss your project with you.
