One of the main complaints regarding standard sash windows is their lack of thermal efficiency. Since the sashes need to slide, there is naturally a little gap in between the sash and the frame. Expert draught-proofing includes machining discrete grooves into the window parts and installing brush strips or "pile" carriers. This removes rattles, decreases dust ingress, and substantially enhances heat retention without modifying the window's look.
4. Double Glazing Retrofitting
For home owners seeking contemporary thermal performance within historical frames, numerous professionals provide retrofitting services. This includes replacing the original single-pane glass with slim-profile double-glazing systems. These systems are specifically developed to fit into the existing rebates of conventional sashes, maintaining the fragile "sightlines" of the structure.
