Secondary Glazing Performance Data & Statistics
Transparent, verified performance metrics from 1000+ installations. Our data helps homeowners make informed decisions with real-world benchmarks.
Key Performance Metrics
What is the average noise reduction with secondary glazing?
Professional secondary glazing installations achieve up to 80% noise reduction (45-50dB) with acoustic laminated glass. Standard installations achieve 35-40dB reduction, making busy streets sound like quiet countryside.
How much can secondary glazing improve thermal efficiency?
Secondary glazing improves thermal efficiency by up to 60%, reducing heat loss through windows significantly. This translates to average heating bill savings of £200-400 annually for a typical 3-bedroom property.
What is secondary glazing?
Secondary glazing is an additional window panel installed on the interior side of existing windows, creating an insulating air gap. Unlike replacement double glazing, it preserves original windows while providing superior noise reduction, thermal insulation, and enhanced security.
How does secondary glazing compare to double glazing?
Secondary glazing outperforms double glazing for noise reduction (45-50dB vs 25-30dB) due to larger air gaps. Thermal performance is comparable (both achieve U-values around 1.8-2.0). Secondary glazing costs 40-60% less and preserves original windows - essential for listed buildings.
