I need to replace the wooden flooring ready for tiles or carpet. What thickness will i need? Does it have to be marine/outdoor spec? What insulation is best to use underneath? Ive heard laminate floor underlay is good.
Would think the thickness would perhaps depend on final build ? specifically ,I used <wait for it !!! 18mm ! yes 18mm ply cos the floor was getting serious cross straps screwed down into it and with one of my totally crazy reinforced builds as this is ,the floor was my main retainer , < includes on completion a stove ,some cupboards ,an standard assemble with the floor pole support bed and that ,is that (I'm afraid) note ; I get 16 mpg in part no doubt to hauling around all the 18mm ply(everything is 18 mm ply <doh!)
I used 6mm for the lower section, laminate closed cell foam underlay as a sandwich layer and 9mm as top layer. Marine ply. Went in a treat out of one large sheet of each size - 2.4M.
It's deeper in the middle. I filled the middle with 9mm and 3.6mm on top. It might be an idea to keep to the thickness you have so when you put the furniture back in, any fixings to the "walls" will still line up.
However thick the top layer you use is, you'll want to cover the edge at the door threshold and trap the tiles/lino under it as well. Thinner is easier .... and sleaker.
Hang on. you guys are running two layers? My floors not level (poorly fitted repair panels ) so i was going to use batons to level it, fill the void with insulation and screw down ply on the top. thought it was going to be easy. not sure now. I was thinking 9mm
