Stay Away from Foil-Faced Bubble Wrap - GreenBuildingAdvisor
网页2014年3月21日 · This R-1 product can be used to make Halloween costumes, but should never be used as insulation. Foil-faced bubble wrap is a thin product that comes in a roll. Its R-value is dismally low. Most brands of foil-faced bubble wrap are only 3/8 inch thick or less, and have an R-value of only 1.0 or 1.1.
Painting foil-faced foam board - GreenBuildingAdvisor
网页2019年3月1日 · Painting foil-faced foam board. So would like to put up Dow Thermax up in my basement. I can get seconds, which are foil faced, for well less than half of new. If buying new, I would get the white version. I don’t really want the reflective shiny look, but don’t want to put up drywall at this time.
Which way should the foil facing on polyiso rigid foam face?
网页2017年12月16日 · I was thinking of not sealing the perimeter prior to installing the rigid foam to give any moisture entering the cavity an avenue to escape. Although no moisture should really be entering the cavity from the inside and to the best of my knowledge, polyiso is vapor-impermeable (not sure about the 1 part foam but I think it is vapor-permeable).
Foil faced insulation on basement walls? - GreenBuildingAdvisor
网页2022年8月21日 · I’m in climate zone 7. A previous owner had insulated the concrete basement walls with 1.5″ of foam with thin wood paneling attached directly on top. In some areas there was fiberglass insulation in a 3.5″ cavity directly against the concrete. Totally inadequate and not up to code. The basement is relatively dry and it rarely gets very ...
Orienting Foil-Faced Foam-Board Insulation
网页2020年11月22日 · The foil is a radiant barrier. If the radiant barrier faces an air space, then the air space will add between R-1 and R-2 to the R-value of your wall assembly. If the foil doesn't face an air space, it won't add any R-value. Of course, the polyiso has an R-value independent of the R-value of the air space.”. BILL WICHERS | Nov 24, 2020 04 ...
Is Bubble Wrap Duct Insulation a Good Idea?
网页2010年8月23日 · It “sort of works,” said Green Building Advisor Michael Chandler, but a better option is installing foil-faced duct insulation (not foil-faced bubble wrap) after ducts have been sealed with mastic and checked for air-tightness, preferably by an independent tester. Foil-faced bubble wrap “is not Energy Star or Manual D approved,” he ...
Attaching Foil-Faced Polyiso to the Inside of a Finished Wall
网页2014年11月17日 · One way to improve the situation is to install horizontal or vertical furring strips, 16 inches o.c., between the rigid foam and the drywall. If the rigid foam is foil-faced, this air space will have an R-value of R-2 or R-3. The furring strips are not necessary, however. I have installed drywall over 2-inch rigid foam without furring strips.

Condensation on foil-faced polyiso panels? - GreenBuildingAdvisor
网页2013年11月27日 · I stacked a bunch of 2" thick foil-faced polyiso insulation boards in the basement of our house, to prep for a major remodeling project. I returned a week later and noticed a puddle of water under the polyiso boards. (This happened in June, in a house along the shore in Massachusetts. The weather was humid, as usual.) "Oh, no! A water leak!", was my first thought. I examined all of the copper ...
