Acoustic Performance

With noise pollution on the increase many customers are looking for window solutions that reduce the levels of unwanted sound entering their property. As standard all of our products are fitted with acoustic weather seals to reduce outside noise. There is also the option to upgrade the glass specification on all of our to include Laminated Sound Control Acoustic glass to further improve the acoustic performance.

With independent UKAS testing by Sound Research Laboratories Ltd our products achieved a rating in accordance with BSEN ISO 717-1:1997 of:-

Spring Sash : RW (C;Ctr) = 36 (-2;-5)dB
Box Sash : RW (C;Ctr) = 36 (-1;-4)dB
Casement : RW (C;Ctr) = 40 (-2;-6)dB
