Professionals utilize a specific stock of materials developed for longevity and heritage compliance:
Accoya Wood: A chemically modified wood that is practically rot-proof and extremely steady.Toughened Heritage Glass: Thinner than standard double glazing but offering comparable thermal properties.High-Performance Resins: Two-part epoxy systems that bond with old wood to develop a repair more powerful than the original wood.Strong Brass Hardware: High-quality sheaves and fasteners that resist corrosion.Often Asked Questions (FAQ)
Can sash windows be double-glazed during the repair process?Yes. Specialists can frequently install "slim-lite" double-glazed units into existing wood sashes.
