Hi all, Wonder if anyone in the know could give me their opinion on this...I've bought a new property a few months ago and have been doing some modernisation. We've taken out the radiators and put in an underfloor heating system - overlay boards onto concrete downstairs and spreader plates upstairs with a new cement board subfloor. My builder has recommended a flooring specialist who's quoted me to fit Quickstep Impressive 8mm laminate. His quote includes underlay suitable for UFH, however halfway through the job I realised he's using Ball & Young Roma underlay - this is a product for carpet, not laminate, and is 7mm foam with a good bit of give to it. This doesn't feel to me like the right product for the job, but unfortunately we're quite far along now and have reinstated the skirtings...to undo this is going to be time consuming and costly, and I'm not sure if the risk of damage years down the line is worth ripping everything up now. What do people think, is this a major problem in waiting or is Quickstep a good enough product that it will be able to sustain a bit of wiggle? All advice welcome!!
