hi my name is herb
i,m trying to find out if there is something that i can put under plywood that will be screwed to the concrete floor. would it be possible to put aluminum bubble wrap or just plastic sheet or felt paper or roofing paper.
Yes it is possible to use many products. However I would suggest one of the commercially available products like Enviro Cushion or Cosella Dorken both have a dimply sheeting that will also give you an air gap.
