Sash and Case windows have been in use since the late seventeenth century.
A timber framework which encased a pulley system with weights to counterbalance the heavy glass used at the time, they caught on and were installed in great numbers from the 1680s onwards. As a result, many historic buildings still contain significant numbers of older sash and case windows – making replacement and upgrading difficult, and causing extensive heat loss.
Ogree mouldings are applied to the inside of the sash profiles. The top frame can be fitted with decorative horns on the outside.
The long life of the wood is guaranteed by the use of slowly grown Scandinavian pine and the GORI treatment system. Double glazed sealed units are argon filled and highly energy efficient to maximise both energy saving performance and noise reduction.
Anti solar and safety glass is also available as an option – please contact us for more details.
