What flooring underlay do you need?


At Discount Flooring Depot our Fibreboard underlay has been produced to offer extra stability when placed over wooden subfloors. This also ensures that the 5.5mm Fibreboard Underlay has a soundproof rating of 18 dB. So as well as dampening sound this underlay will help to level uneven subfloors.

Created from natural wood fibre our Fibreboard underlay is environmentally friendly while providing an insulting 1.1 tog rating. This also means that this underlay is not suitable for concrete subfloors as there is no moisture barrier.

Review Summary - 4.9 out of 5 based on 24 ratings.

average easy bother dent but worked well for the floor

I have to say I was a bit dubious buying from an online company at first, BUT I have to say this is one of the BEST companies I ever bought from!!!! it was like going back in time to where you could actually speak to a person straight away!!! Much better than the big name DIY shops that I’ve recently had terrible customer service from.

The customer service from Discount Flooring Depot was probably the best I’ve ever experienced!!!, it was second to none!!

The first laminate I wanted was out of stock, but they’ve got so many to choose from, so I picked a few more that I liked and a couple of days later I was sent the samples!!

I spoke to about three people and all was really polite responsive and helpful and especially Migdalia who I mainly spoke to on the phone and by email, she responded to my emails as soon as she could and even though I sent an email at the end of the day when they was closed and it was just past her home time, she still responded to me even though she was just leaving to go home, she was so friendly, helpful, polite and sorted everything out for me, what a great asset she is! and all the other people I spoke to.

And the price and the quality of the laminate and underlay I bought was great too!! I’m so please with it, I felt compelled to leave feed back as you don’t get many companies and customers services now a days like Discount Flooring Depot!! Even the delivery of 70 packs of laminate was great!

Thanks so much and I’ll always recommend Discount Flooring Depot, as there’s not many companies like this around anymore

Was expensive but has taken a lot of the movement out of the floor. Went on top of boards in attic room that felt quite unstable. Floor feels sturdier now

Spot on from order to finished floor. Easy to order, and you are kept informed throughout the ordering and delivery process - Even the delivery man lets you know he's on his way and gives an approximate delivery time.

Great value underlay. Allows you to easily run speaker cables etc with a minimum of fuss
