Browse Forums Flooring & Floor Covering 1 Jul 17, 2014 8:11 pm I'm a new member here, and I've read a few posts about underlay and carpets. However, I'm still unsure as to what minimum density I should be looking for? We're about to recarpet the top floor of a 2 storey house, stairs and a small study on the ground floor (concrete slab). I've seen lots of comments about the huge range of underlays available, but I'm unsure if there is a minimum value we should look for to protect the carpet? We're thinking of buying a Quest Pluto Solution Dyed Nylon or Godfrey Hirst Eco Plus carpet, but the 2 suppliers are offering different underlays - one a Dunlop "Gold"(?) 8mm underlay, and the other an 11mm Airstep Supreme underlay. Dunlop can't tell me what the Gold underlay might be without more info, but Airstep have said that the Supreme is a good choice for the Quest carpet. It is 11mm high and 95kg/m2, which I thought sounded good, but I've recently seen posts that seem to suggest something around 100-120kg/m2 is the way to go (e.g. Dunlop Springtred Ultimate (10mm/1120kg/m2) or Supreme (details not supplied, but apparently higher). I've also seen strong support for Dunlop Excellay, which I gather is a commercial underlay, 120kg/m2 but only 7mm thick. I spend a fair few hours in the study, working standing up, so would like some support underfoot, but now appreciate that too much give will damage the carpet. So any suggestions on what minimum underlay density I should be looking for my situation? Thanks in advance.
