Half-pound (0.23 kg) spray foam is probably the most value-efficient, and due to this fact hottest, spray foam insulation. It has an R-worth between 2 and 3.5, мир кровли making it about as dense as dormant air. It’s used as the primary insulation materials in the wall cavities of most house. Due to its low R-worth, it isn’t permitted for vapor and fume control, however nonetheless has the same insulation characteristics of the 2-pound (0.9 kg) foam.

Based in strategic areas all through the U.S., our totally skilled and experienced estimators have entry to the most superior software program and hardware, together with Taper Plus and AutoCAD. The team effectively creates CAD-generated set up shop drawings starting from fundamental tapered layouts to advanced projects requiring quick turnaround time. Firestone Building Products is dedicated to offering correct and timely tapered take-offs that encompass all essential elements affecting proper drainage.

Additionally, slightly regrettably for historically produced XPS, the hydro fluorocarbons (HFCs) mostly used as blowing brokers are far more damaging to the local weather than those used with different rigid foam insulation boards. Some manufacturers speak of a transition to extra eco-pleasant foam insulation blowing brokers; that will probably be great information when it happens across the board! And credit where it’s due, the “real” Styrofoam, as within the DOW Chemicals blue product, is now manufactured with HCFC blowing agents which have 94% less ozone depletion potential. As HFCs have a worldwide warming potential (GWP) that’s 1430 times worse than carbon, this really does demonstrate how necessary it is to choose rigid foam insulation boards very carefuly to reduce their environmental influence. All XPS panels are not equal!
