Westbury Windows & Joinery has recently published its latest in a string of successful test results, following on from its energy and security (PAS24) achievements with acoustic assessment too.

The company’s products were independently tested at a UKAS-accredited laboratory and performed particularly well in the reduction of traffic noise. However, the unexpected star of the show was the French doorset; a product that is notorious, industry-wide, for poor sound insulation.

So far, no other timber door manufacturer has published an acoustic test result for a French doorset, yet Westbury’s has proved to be as effective as a casement window, scoring 38Rw on the Weighted Sound Reduction Index (meaning it reduces sound by approximately 38 decibels).
