This essentially eliminates rattles and substantially reduces heat loss without modifying the window's appearance.
Glazing Upgrades
While many choose to maintain initial crown glass for its "wavy" visual, others go with "slimline" double glazing. These systems are thin adequate to suit original sash profiles, providing the thermal benefits of modern-day windows while maintaining the thin glazing bars essential for a period look.
