Holmes vs. FHB: Basement Floors
FHB has published two articles about making a floor over the concrete slab of your basement. While the two articles differed significantly, both stressed beginning the project with a layer of plastic laid atop the concrete.
I have recently begun watching “Holmes on Homes,” and he disagrees quite strongly with this method. He goes so far as to point out that his disagreement is contrary to the instructions that come with the ‘engineered wood’ floors.
Instead, Holmes places a ‘floating’ layer of rigid foam insulation, and tapes the seams. This has the effect of making the top of the foam the vapor barrier / retarder. It is his position that the sheet of plastic atop the concrete (that FHB advises) will only act to trap moisture, and create a mold / mildew / stink issue.
For a similar reason, he really likes a radiant heat mat as part of the follr (to dry off any moisture) and would just as soon not have ANY wood as part of the floor.
Holmes has a similar approach to concrete walls; a layer of foam, THEN the walls are built.
Well, Breaktimers …. has FHB been giving bad advice?
