Sash windows look gorgeous in older buildings, but they require regular maintenance and are susceptible to issues like wet rot, cracked putty, and drafts. Sealing, replacement or repair of the sash window is an effective method to minimize these issues and increase energy efficiency.
The gaps between the sash and frame are the primary cause of drafts. They can also trigger noise and rattling, which can reduce soundproofing. There are a variety of methods to reduce air leaks in the sash window, such as sealing beads, specialist products and secondary glazing.
A common issue is a gap between the top of the sash and the jamb frame, or between the bottom of sill and the sash. This can lead to water leaking into the wood and rotting of the wood, and mould growth. The gap can be sealed by caulking made of silicone or polyurethane or foam sealant.
Installing a new sash runner or spring bronze might be necessary in the event that a gap blocks the windows from opening and shutting smoothly.
