Moderate Extent of Rot Significant sill or box frame replacement increases labor and products. High Glazing Type Switching from single glazing to vacuum glass or slim double glazing. High Availability Requirements for scaffolding or high-reach platforms. Moderate Paint Stripping Overall elimination of lead-based paints (requires professional security devices).

Accoya ® Timber: A chemically customized wood that is virtually rot-proof and extremely steady, meaning it won't swell or shrink with the seasons. Epoxy Resins: Advanced bonding agents that can support old timber and offer a long-term repair that is stronger than the wood itself. Vacuum Glazing: An ultra-thin glazing option (as thin as 6mm) that provides the thermal efficiency of triple glazing while fitting into the original thin refunds of 18th-century sashes. Often Asked Questions (FAQ) 1. Can rotten sash windows actually be conserved? In the huge majority of cases, yes.
