Description

The perfect choice for installation on top of an existing tiled floor or an uneven floor. If you are worried about the subfloor being uneven, this is the best underlay in the Quickstep range to use. Quickstep Thermolevel also provides extra insulation so you don't have to worry about it. Also attached is a damp proof layer so no additional surface dpm is required, just lay this first and install your new floor on top!

Questions & Answers

Hello. Can this be used with Polyflor expona encore rigid loc flooring? It will be laid on a wooden floor which is quite uneven and cold.

Asked by Ben Cowley on 04 May 2021

1 Answer
Hi there. The polyflor encore range has a pre-attached underlay, which is designed for uneven subfloors. If your subfloor is quite uneven and you're worried, we would recommend plying beforehand.

Hi! Could you tell me the density of this, please?

Asked by Dmitriy Ermakov from Russia on 08 Mar 2021

1 Answer
Hi there, Here is the full technical specification from Quickstep : https://static.flooringsupplies.co.uk/downloads/New%20Downloads/Datasheets/TDS%20QS%20Thermolevel%20-%20EN.pdf

Can this be cut and fitted using only a knife? How difficult to install compared to basic foam underlay?

Asked by Matthew Thomson from LARBERT on 27 Apr 2020

1 Answer
This can just be cut with a knife, and is straightforward to fit.

Can this underlay be used directly onto existing floorboards?

Asked by Abigail Shepherd on 25 Feb 2019

1 Answer
Hi there, This can be laid onto existing subfloors, even those that are minimally uneven as it is designed to help level it out.

We're looking at the Quickstep Saw Cut grey oak for use throughout our Hall, Dining room and Conservatory. The hall and dining room are concrete floors and relatively level although we're hoping this Thermo level over comes that, but the conservatory is tile. Is this product suitable for use in the conservatory as the impressive range is so we need something to match and be covered by warranty? Also would this underlay give a solid feel to the floor and not a bouncy feel as we've had using previous laminate and underlay (different supplier)

Asked by Damon Piall on 28 Sep 2018

1 Answer
The thermolevel is made for use on top of tiled subfloors, so it will work fine in the conservatory. It isn’t a particularly bouncy underlay, so it should feel rigid underfoot. If you need any further assistance please drop us an email to sales@flooringsupplies.co.uk or give us a call on 0800 999 810 and one of our team will be happy to help.

Is this underlay suitable for use with solid wood flooring such as bamboo?

Asked by sarah long on 13 May 2018

1 Answer
Hi Sarah, this underlay is designed for use with laminate flooring - almost all solid wood floors are attached directly to the subfloor, without an underlay

Hi - does this underlay also provide any sound proofing? Thanks

Asked by Louise from London on 30 Apr 2018

1 Answer
Hi Louise, it certainly does. You can read a little more in the data sheet, here: https://static.flooringsupplies.co.uk/downloads/New%20Downloads/Datasheets/TDS%20QS%20Thermolevel%20-%20EN.pdf

Hi, I will be buying some quickstep thermolevel underlay for my very cold concrete kitchen floor . Would it be adviseable to put a dpm down also ? If so what thickness ? Thanks

Asked by Pauline Crowther from Norfolk on 23 Dec 2017

1 Answer
Hi Pauline, this underlay has a built-in DPM, so it sounds like the perfect choice for your kitchen.

Hi, can I use two different layers underneath a laminate flooring? I have a wooden subfloor in most of the house and 2 rooms with a concrete subfloor. Both seem quite uneven. Can I use The Thermolevel underlay on top of a cheaper 2mm underlay so that I have a thicker result? And also: can I use this underneath a Pergo Coastal oak laminate? Thanks

Asked by ILEANA POP from Weston-super-Mare on 13 Apr 2017

1 Answer
Hi Ileana, We wouldn't recommend this, as it could cause your floor to become bouncy, which would lead to problems later down the line. Instead, we'd recommend levelling the subfloor first with hardboard or screed, and then installing a single underlay over the top.

hi I have used basic quickstep foam underlay before but found it cold. is this a better option for insulation on a concrete floor?

Asked by zandra Tomkinson from Ms on 16 Mar 2017

1 Answer
Hi Zandra This product is a much better option for insulation.

Hi, how uneven can the subfloor be with this product? ie mm per m. Thanks Luke.

Asked by Luke townsend from Huntingdon on 04 Dec 2016

1 Answer
Hi Luke, For the best results we recommend that subfloors don't deviate by more than 3mm over 1m.

Is the thermolevel underlay a good option for a concrete floor and as it is a ground floor, do you think we should use soft board and screen under the underlay? Will the thermolevel be warm enough on its own.

Asked by Christopher Vivian from Harrow on 18 Feb 2016

1 Answer
Hi Christopher, Any extra layers and weight will improve thermal insulation, but most customers will just use this on its own. There's no reason why you can't use both, so it's up to you, really!

Hi - can you tell me the R Value for this product? Thanks.

Asked by J Cook on 18 Jan 2016

Hi, The R value for this underlay is 0.143 m²K/W. Thanks

Do I need to tape the joins ? If so what tape do you recommend ?

Asked by John Culley from harwich on 05 Jan 2016

1 Answer
Hi John, Yes, whilst not everybody does it, the official recommendation is to tape the joins. Any waterproof cloth tape (like Gaffer Tape) will work.

Asked by Chris Bouwers on 12 Nov 2015

1 Answer
Good Afternoon Butted up against the wall will be fine.

Can this be placed on top of the Basic Plus Underlay to give an extra layer of insulation?

Asked by Tim Ottewell on 06 Nov 2015
