Professional draught-proofing involves machining discrete grooves into the window elements and setting up brush strips or “stack” carriers. This gets rid of rattles, lowers dust ingress, and significantly enhances heat retention without changing the window’s look.
4. Double Glazing Retrofitting
For homeowner seeking modern-day thermal performance within historical frames, lots of experts provide retrofitting services.
