Acoustic testing of the DUALFRAME window system means that the effects of noise pollution at sensitive sites can be reduced

Sound reasons to opt for Dualframe

Sapa Building Systems has subjected its DUALFRAME window system to a series of acoustic tests to demonstrate how the system can minimise noise pollution at sensitive sites.

With more and more new build developments taking place on 'brownfield' and other 'noisy' sites, there has been growing concern about the potential for noise pollution to affect the buildings with specifiers becoming ever more aware of the need to provide insulation that minimises the problem for the building's occupants.

BS8233:1999 - Sound Insulation & Noise Reduction for Buildings – Code of Practice gives recommended interior noise levels for various types of room occupancy and usage: This is increasingly being used by specifiers to ensure a comfortable and safe working and living environment. Specifiers now expect data to be provided regarding the performance of the window as a whole, not just the glazing materials, as this issue becomes an increasingly important design criterion.

Sapa’s involvement in a major project for Barratt Homes in Brighton demanded that they subject the Dualframe system to acoustic testing in order to be sure that it met the demands of the specifiers for minimising the noise pollution at the project site, which was adjacent to busy roads and a railway line.

Three Dualframe windows – 55mm Tilt before Turn, 55mm Pivot and 75mm Casement - were tested with varying configurations of Pilkington double glazed sealed units at Sound Research Laboratories and all were found to provide high levels of acoustic protection.

The success of the tests provides specifiers with a measurable performance when projects give rise to the need for good acoustic protection.
