Double glazing your existing sash windows, including the installation of our unique perimeter draught seal system
The cost effective solution for conservation areas
It has long been thought that to have double glazed sash windows would mean replacing the entire window which can be costly and disruptive to your home, here at JTP Joinery we have an innovative solution to this.
We are able to manufacture replacement sashes (the moving parts) that fit within your existing box frames, replicating the finer details such as glazing bars and decorative horns. The new sashes will incorporate Slim line heritage double glazing to maintain the character and charm of your windows whilst vastly improving your heat retention.
Our slim line heritage double glazed units come with warm edge super spacer bars as standard, Argon gas and employ the latest Planitherm glass technology for maximum thermal efficiency.
Your replacement sashes can be manufactured from a range of timbers to suit all requirements and budgets from Scandinavian Redwood to Solid Hardwood although our recommended timber is usually Accoya.
All replacement sashes will have 2 coats of micro porous paint applied prior to installation.
