In this video, we demonstrate the real-world performance of our 49dB-rated secondary glazing system, specifically designed for traditional sash windows. Better than sash window seals.
Filmed in central London on a busy main road, this footage captures live sound readings before and after installation—highlighting the dramatic difference our acoustic solution can make. You'll see several stages of window closure, from just the original sash shut to both the sash and secondary glazing fully sealed.
The sound environment includes constant traffic noise, lorries, buses, and motorbikes—making this the perfect setting to showcase the true effectiveness of our system.
Whether you're considering soundproofing for a period property or just curious about the impact of high-performance secondary glazing, this demonstration gives you clear, measurable results.
