Underlayment for vinyl plank flooring11/23/2023 So in one bad spot I took up a piece of the tile and found that the subfloor seems to be a thick mud or concrete base over wood slats (home was built in the early 50’s). It didn’t take long for the tile to conform to the bad subfloor below, you can see dips and in a several places, cracks, etc. The previous owner must have put in 12x12” adhesive backed tile for the floor right before selling it. So in the meantime I need to do a couple of upgrades, primary among them my floor. With the way the economy is and the size of my paycheck, that may be several years away. I’ve been avoiding a kitchen re-do until I put on an addition & tore everything out. Check out the installation docs for any radiant flooring solution - they will tell you that you need something between the slab and the heating system (which goes under the floor), or else you are just wasting energy because the concrete acts as a heat sink. I disagree that you should not have an underlayment, which is why I am looking into one. It might flex more which would be a deal breaker. What do you guys think about 1/4" EasyBoard (or Wedi board) with 1/4" plywood over top of that? After reading into Jumpax, I don't think it would be all that different (albeit 1/8" thicker). ![]() That is an intriguing idea though, warmsmeallup. I would then need to worry about door clearances and transitions. It doesn't look like The Barrier would be a good solution since it's designed to go under the slab, and more importantly it would just be too thick for my floor. Jumpax is essentially a two-part system, with the bottom being 3mm polystyrene with ~1mm aluminum sheet underneath, and the top overlapping the seams of the bottom with 6mm MDF and adhesive. I would prefer something no thicker than 10mm or 3/8". The Jumpax seems to be an ideal solution, but it is $3.20 per square foot, which seems pretty steep for what I want. ![]() So far I have found these which appear to have at least some foam component: Vinyl plank has unique requirements, since the underlayment cannot flex much. I would like to find a good underlayment for vinyl plank flooring (4"x36"x3mm tiles) so that there is some insulation between the concrete and the floor, which I have found is common for radiant heating systems. The concrete slab is the floor to the lower level of my bi-level home, which currently has carpet.įortunately, before installing the vinyl, I realized that it may be a bad idea to install it on the concrete slab because the floors will get very cold in the Winter months. I chose the vinyl because of its waterproof properties and that it wears well. I bought Vinyl Plank Flooring (Novalis) recently, and had planned to install it directly over my concrete slab. I am installing some flooring and need some advice.
