Understanding Draught Proofing for Sash Windows

Draught proofing sash windows involves sealing gaps around frames, sashes, and hardware to eliminate air leakage. This process not only improves thermal performance but also prevents moisture buildup, reducing the risk of condensation and wood rot—common issues in older sash installations. Modern sealants and weatherstripping offer durable, invisible solutions that preserve the window’s original appearance while delivering proven performance.

Effective draught proofing combines precision sealing of frame joints, replacing worn weatherstripping, and ensuring sash movement doesn’t compromise airtightness.
