Clwyd based contractor utilises tranquilt for ‘Gateway to Wales’ community housing project

A three-storey apartment building being constructed at Sealand in Flint, has featured the use of Monarfloor Tranquilt acoustic membrane. As part of the extensive Icopal range, the product played an important role in the multiple occupancy structure achieving compliance with Part E of the Building Regulations.

Part of the Gateway to Wales project, the Maes Helyg development is being built for the Pennaf Housing Group to provide a total of 15 two-bed apartments and half a dozen single bedroom dwellings for affordable rent. Across the Principality, the group manages some 5,600 homes, providing both general needs accommodation and elderly care facilities.

The design & build contractor, Anwyl Construction, had previously made use of Tranquilt for another social housing development in Wrexham, and found it ideal for addressing the issue of acoustic transmission and flanking sound through floor slabs.

The Design Manager for Anwyl Construction, Martin Gunn, commented:

“While this was a design and build project, and we could have employed whichever products we wanted, we saw no need to change the performance specification for the acoustic membrane; having used Icopal’s Tranquilt successfully on a couple of other projects.”

“It worked very successfully then and, interestingly, although this project is making use of Robust Details for all the acoustic requirements, the organisation (Robust Details Ltd.) has just chosen the building to carry out one of its routine inspections with in-situ testing. They have to test RDs every 12 months to confirm they are still working correctly, and we are confident all the systems will pass.”

In total 1200 square metres of Tranquilt, supplied through merchant CCF, have been installed by the screeding contractor, Merseyside based John Cothliff Ltd., working in accordance with the manufacturer’s application guidance.

Monarfloor Tranquilt creates an acoustic isolation layer between a concrete subfloor and a floating screed to help specifications exceed the requirements of Approved Document E to the Building Regulations. It also provides credits towards EcoHomes and the Code for Sustainable Homes.

It is supplied in 20m x 1.5m rolls with adhesive and tape for jointing at wall junctions and around service pipes.
