Specialized restoration services often use advanced epoxy resins rather than simply changing areas of wood. This allows the professional to protect as much of the original historic wood as possible while developing a surface that is more powerful than the initial wood.
3. Draught Proofing Systems
Among the main grievances relating to traditional sash windows is their absence of thermal performance. Since the sashes should move, there is naturally a small gap between the sash and the frame. Expert draught-proofing involves machining discrete grooves into the window elements and installing brush strips or "pile" carriers. This gets rid of rattles, reduces dust ingress, and considerably improves heat retention without changing the window's appearance.
4. Double Glazing Retrofitting
For home owners looking for modern-day thermal efficiency within historic frames, lots of experts provide retrofitting services.
