2. Draughts and Thermal Inefficiency
Traditional single glazing and the inherent spaces required for sash windows to slide smoothly result in considerable heat loss. This often causes a cold living environment and high energy bills.
3. Paint Seizure and Rattle
Years of over-painting can result in windows being "painted shut." Conversely, timber shrinking over a century can cause sashes to fit loosely in their frames, leading to irritating rattles during windy weather.

Draught-Proofing Installation
Among the most significant upgrades during restoration is the setup of a comprehensive draught-proofing system. This involves machining grooves into the sashes or beads and placing brush piles or silicone seals. This practically eliminates rattles and considerably decreases heat loss without altering the window's appearance.
Glazing Upgrades
While many pick to maintain initial crown glass for its "wavy" aesthetic, others choose "slimline" double glazing. These systems are thin enough to fit into initial sash profiles, offering the thermal advantages of modern-day windows while preserving the thin glazing bars vital for a period appearance.
