Straight Slider Sash Windows

The vertical straight slider sash windows have been made for the last 300 years or more. In this window however we have two modifications. Firstly, the sashes are operated by spring balances, and secondly, we have applied up-to-date technology and design to the seals.

The sashes are secured with a fitch fastener.
