Questions & Answers

Is there only one quickstep Unisound? or are there two; Unisound and Unisound Combiflor?

Asked by Anj on 13 Nov 2018

1 Answer

Hi Anj, There is just the 1 underlay, the Unisound Combiflor. Thanks Shazney

Hi, I'm going to have laminate installed in my kitchen/diner. There are slight imperfections in the current sub floor. Would this underlay be suitable?

Asked by Steve Mann from Chelmsford on 31 Dec 2017

1 Answer

Hi Steve, we'd always recommend levelling a subfloor to less than 3mm deviation across a 1m area. However, if you'd like to use an underlay to cover imperfections, your best choice will be the Quickstep Thermolevel Underlay, which can be found here: https://www.flooringsupplies.co.uk/product/50/quickstep_thermolevel_underlay

Hi, I am laying wood flooring in a first floor bedroom, above the living room. I want to get the best underlay possible for sound reduction (as well as of course insulation). Would you recommend this particular underlay? With thanks, S.

Asked by Sorrel Osborne on 13 Oct 2017

1 Answer

Hi Sorrel, this underlay is great for insulation, and can reduce impact sound insulation by up to 19dB. We've got a full datasheet for this underlay here: https://static.flooringsupplies.co.uk/downloads/New%20Downloads/Datasheets/TDS%20QS%20New%20Unisound%20-%20EN.pdf

Can you please let me know what thentog ratimgbis for this underlay as I intend to use electric underfloor heating.

Asked by Deep Bassi from London on 04 Oct 2017

1 Answer

Hi Deep. These products aren't measured for their Tog Rating, however, the thermal resistance is measured as 0,049 m² °K/W. We wouldn't recommend this as the best underlay for underfloor heating. Instead, we'd recommend the following product, which is designed for the specific purpose: https://www.flooringsupplies.co.uk/product/18591/quickstep_lvt_heat_underlay

Hi. Is Quickstep Unisound Combiflor Underlay suitable for upstairs bedroom floors? The floor is reasonably flat chipboard in an a 10 year old house, and will have 10mm laminate over it.

Asked by paul n from sheffield on 24 Jul 2017

1 Answer

Hi Paul, yes, this underlay will be suitable for your room.

Is it possible to use this underlay with any type of flooring

Asked by Nick Moulson on 15 May 2017

1 Answer

Hi Nick, Underlays are very versatile and can be used with most floating floor systems, but there are exceptions. If you let us know the floor you're installing and the room it's going in, we can let you know the best underlay.
