Fiberglass has an R-value of approximately 2.2 to 2.7 per inch of thickness. Because it’s made with glass, it has a comparatively low environmental affect and presents both an excellent R-value and first rate soundproofing (although not pretty much as good as rock wool).

The combined R-worth of the batts and board on the 2×4 wall was more than batts alone on a 2×6 wall, and he would gain somewhat additional space within the room. Before switching to spray foam insulation, Tom used to use polyisocyanurate panels that method-he would build a 2×4 wall, insulate between the studs with batting (paper face eliminated), then cover the entire thing with foil-confronted panels and seal them with foil tape before putting up wall board.

Mineral wool insulation for a similar wall runs about $1 to $1.10 per square foot. Mineral wool is heavier than fiberglass, but the batts are also stiffer, so that they don’t bend or flop over as simply. Mineral wool has a barely greater R-worth, ranging between 3.0 and 3.Three per inch. R-Value: The thermal resistance of insulation is measured by what’s generally recognized because the R-worth, and the higher the R-value, the higher. These thermal curtains add a classy look to your dwelling area while decreasing your power invoice.
