Avoid Disputes on Poor Acoustic Performance with Pulse Testing

RISA has highlighted the benefits of pulse testing for window installations in properties where improved acoustic performance is the primary objective, but where customers are actually reporting worse noise levels, post installation, due to the specification of trickle vents.

RISA offers its pulse testing service to all installers. It was introduced following the update to Approved Document F for ventilation and indoor air quality, legislation that typically requires the use of trickle vents to be incorporated into new windows and doors.

Pulse testing, however, is designed to demonstrate the airtightness of a building pre and post installation, and in many cases when the reading doesn’t change, it provides installers with certified evidence to prove there is actually no requirement for additional trickle vents.

For installation projects on buildings that are located close to busy roads or under flight paths, where customers are paying for a high-quality solution to reduce the amount of noise into their property, pulse testing provides a valuable alternative route to compliance by significantly reducing the chance of customer disputes.

Lee Galley, Independent Inspection and Assessment Manager for RISA, said: “We’ve had a spate of inspection requests recently for installations where noise infiltration is the main cause of the dispute.

“These have primarily been for projects where improved acoustic performance was the main reason for purchasing new windows, and where the specification includes acoustic rated glass, but the homeowner is adamant that noise levels are worse compared to the old windows.

“In most cases, this is because trickle vents have also been included in the specification,” he continued. “Installers should be commended for doing their best to follow the regulations, but they should also be made aware that trickle vents are not always necessary and in fact can result in disappointed customers who are paying a premium for a quieter and more comfortable home.

“There is an additional cost involved in pulse testing, but we would suggest it’s easily justified under such circumstances, especially when installers will ultimately benefit from positive customer feedback, as well as avoiding the costly time and hassle of resolving harmful disputes.”

Pulse testing takes less than half an hour to complete and the results are available immediately. The technology is quick and easy to use and can be done so with people in the property, allowing for a convenient addition to the installation process.
