Because the sashes should move, there is naturally a little gap in between the sash and the frame. Expert draught-proofing involves machining discrete grooves into the window parts and setting up brush strips or "pile" carriers. This eliminates rattles, minimizes dust ingress, and considerably improves heat retention without modifying the window's look.

4. Double Glazing Retrofitting

For homeowner seeking modern-day thermal performance within historic frames, many specialists offer retrofitting services.  learn more  involves replacing the original single-pane glass with slim-profile double-glazing systems.
