Traditional Box Sliding Sash Windows
This double hung sliding sash timber window uses counter weight pulleys and weights. It is used mainly in listed buildings where single glazing is enforced but it can be double glazed by introducing lead weights.

The traditional box design is based on the same design we have been manufacturing for over 100 years but with exceptional air and water performance through careful modern design.

Spiral Balance Sliding Sash Windows
This is a modern timber version of the double hung timber sliding sash window which uses tensioned springs in lieu of pulleys and weights.

Super-tilt Sliding Sash Windows
This is a variation of the spiral sliding sash window which allows each sash to tilt inwards to enable easy cleaning from inside.
