Heat loss through single-pane windows can account for approximately 25% of a home’s total energy waste. By adding a second layer of glass, an insulating pocket of air is produced. This “thermal buffer” reduces drafts and helps keep a constant internal temperature, resulting in lower energy expenses and a decreased carbon footprint.
2. Superior Acoustic Performance
While double glazing is excellent for thermal retention, secondary glazing is often remarkable for soundproofing. In a double-glazed system, the two panes of glass are spaced really closely together (normally 16mm to 20mm). Secondary glazing enables a broader space (normally 100mm to 200mm), which acts as a more reliable barrier versus low-frequency traffic noise and urban disruptions.
3. Conservation of Heritage
