This "thermal buffer" reduces drafts and helps preserve a consistent internal temperature, causing lower energy costs and a minimized carbon footprint.
2. Superior Acoustic Performance
While double glazing is exceptional for thermal retention, secondary glazing is often exceptional for soundproofing. In a double-glazed system, the two panes of glass are spaced extremely closely together (typically 16mm to 20mm). Secondary glazing enables a broader gap (generally 100mm to 200mm), which functions as a more reliable barrier versus low-frequency traffic noise and city disruptions.
3. Conservation of Heritage
