Minimising noise from building services such as heating, ventilation and wastewater drainage is key to helping produce a pleasant environment for a building’s occupants as well as for neighbouring properties, says an article from PBC Today.
Polypipe’s Acoustic Expansion Couplers have been designed to address the issue of unwanted noise in soil stacks, which is caused by thermal movement and unplanned contact between the stack and structure of the building.
The coupler limits the transfer of noise by allowing thermal movement to happen with the rubber gasket in the fitting (up to 15mm). Normal working practice for standard soil couplers is to withdraw the fitting when installed with the pipe by 10mm. With our Acoustic Expansion Coupler, this action is no longer required. This provides certainty that expansion has been allowed for during installation.
Franz Huelle of the BPF Pipes Group has been quoted as saying:
“There are currently no UK, European or sector standards in existence that specify the acoustic performance of soil and waste pipes, and yet designers are constantly seeking to reduce noise in modern buildings.”
“Combining the traditional benefits of weight and quick jointing with state-of-the-art design and manufacturing in a complete soil and waste systems solution with added acoustic performance is ideal to help those designing building services to meet and exceed modern expectations.”
