What needs to go between hot water radiant floor heating and vinyl floor covering?
What needs to go between hot water radiant floor heating and vinyl floor covering?
I'm redoing my kitchen from the floor up. I will have a 3/4" sub floor, then hot water tubes running through aluminum channels. This leaves a surface that is very flat, with just small unevenness at each tube. Is it enough to lay 1/4" plywood over that, then the vinyl flooring? Or does there need to be a thicker plywood layer at that point?
Answers:
rockntaz: i wouls say thicker plywood but why would u want to put hot water thru aluminum channels under a vinyl floor anyway?....u could chance warping the vinyl then have to replace it all

hawk1151: all flooring should be 3/4 thicc. naything less will not last. it will warp and wobble. you could use the 1/4" plywood and on top of it 1/2 rockboard then the vinyl. as long as the sum is 3/4

Rusty Nail: The 1/4 inch plywood will flex too much and you will be walking on a sponge. Put 5/8 MDF and then your vinyl flooring.

rob s: Putting a floor over what you have is a challenge since you take a chance of nailing thru a tube.. Does it have to be vinyl? Laminate will spand that channel.. Or you may have to pour a self leveling compound over every thing to fill the channels and over the 3/4 a bit. This stuff can be poured up to an inch if needed.You may have to pre pour the channels 1 st and let dry so it s not to thick over all Thickness will vary as to what product you use. A primer (special latex primer) needs to be used 1 st.. Once total pour is over all the floor vinyl can be laid directly over that because it s just like cement I use this system over my electric wires on heated bath foors when I set ceramic over it GL
