6. Glazing Upgrades: Depending on the customer's needs, initial glass might be maintained, or "Slimlite" double glazing can be installed to improve thermal efficiency without changing the window's profile.

• Epoxy Resins: Advanced bonding agents that can support old lumber and supply a long-term repair work that is stronger than the wood itself.
• Vacuum Glazing: An ultra-thin glazing alternative (as thin as 6mm) that provides the thermal efficiency of triple glazing while fitting into the original thin refunds of 18th-century sashes.

1. Can rotten sash windows actually be saved?

In the huge bulk of cases, yes. Even when wood appears seriously decayed, a professional can usually replace the rotten sections (such as the sills or bottom rails) while keeping the original frame and upper sashes undamaged.
