A leading sash window repair business does not just use 19th-century strategies; they integrate contemporary material science to enhance the window's efficiency.
Accoya ® Timber: A chemically customized wood that is virtually rot-proof and incredibly steady, suggesting it won't swell or shrink with the seasons.Epoxy Resins: Advanced bonding agents that can stabilize old lumber and provide a long-term repair work that is stronger than the wood itself.Vacuum Glazing: An ultra-thin glazing option (as thin as 6mm) that uses the thermal performance of triple glazing while fitting into the initial thin rebates of 18th-century sashes.Often Asked Questions (FAQ)1. Can rotten sash windows actually be conserved?
In the huge majority of cases, yes. Even when lumber appears badly decomposed, a specialist can normally replace the rotten areas (such as the sills or bottom rails) while keeping the original frame and upper sashes undamaged.
