QuickTherm Vapour features a unique perforated design and ultra-low tog value, which helps your underfloor heating work at its best. It also has a separate vapour barrier, which stops moisture rising from the subfloor and keeps your room damp-free. It's also really lightweight, which makes it easy to move around and install under your floor.

Questions & Answers

Hi, could you please comment on the acoustic properties of this underlay, I appreciate it is not an acoustic underlay, but it would be good to know what it is. Many thanks, Will

Asked by Will from Brighton on 09 Feb 2018

Hi Will, I'm afraid the acoustic properties of this underlay are so minimal, that it doesn't have an official rating.

Hi We have an over floor wet UFH system and want to use this underlay with engineered wood. How does this need to be installed? Does it need to be fastened in any way? Does it require taping along the edges?

Asked by Melanie Forster-Nel on 04 Jan 2018

1 Answer

Hi Melanie, this product can be simply laid on top of the subfloor and taped together along the edges.
