Top quality systems can lower heat loss through windows by approximately 60%, causing lower energy expenses and a smaller carbon footprint.
2. Acoustic Performance
For homes located near hectic roads, airports, or railway lines, sound pollution is a significant concern. Professional secondary glazing companies utilize specialized acoustic glass and particular air-gap widths (usually 100mm to 200mm) to dampen sound.
