Professional draught-proofing includes machining discrete grooves into the window parts and setting up brush strips or "pile" carriers. This removes rattles, lowers dust ingress, and significantly enhances heat retention without changing the window's appearance.
4. Double Glazing Retrofitting
For homeowner looking for contemporary thermal efficiency within historical frames, many professionals use retrofitting services.
