This doesn't solve the problem, it just moves it. Instead of the moisture condensating on the cold concrete, it will travel through the porous wood and condensate on the plastic layer beneath it and then since the plastic is impermeable, it will just pool in the little dimples and just sit there, eventually wicking back up into the wood itself causing wood rot and mold. At least in the first scenario the moisture would wick into the concrete and go away as you said. The best way to avoid this all together is still removing the source of the moisture itself eg. dehumidifier. Dry air is the best defense against a musty space.
I don't agree. Like a plastic vapour barrier, the plastic membrane beneath the OSB will create a vapour barrier not allowing wet warm air coming into contact with the cold concrete and condensating. Though I have heard these tiles struggle with their vapour barrier capabilities. From all the research I've done, a dimple membrane like the kind used on the exterior of foundations is better because you can tape it off and create a proper vapour barrier on the floor. If any condensation does occur on the concrete slab, it can air out as a result of the raised nature of the dimple membrane, same reason it exists on the exterior.
Should you add insulation to a basement subfloor and if so, would you use this same product or something different?
I really appreciate your video! Subscribed!
thanks for the tip!
I just don’t dog the hollow feet once you rip a panel . Water can come in contact with the osb and swell, mold , and fail.
