Half-pound (0.23 kg) spray foam is probably the most cost-efficient, and subsequently hottest, spray foam insulation. It has an R-worth between 2 and 3.5, making it about as dense as dormant air. It is used as the primary insulation materials in the wall cavities of most home. Due to its low R-worth, it is not authorised for vapor and fume control, however nonetheless has the same insulation characteristics of the 2-pound (0.9 kg) foam.

Primarily based in strategic places throughout the U.S., our totally educated and skilled estimators have access to the most superior software program and hardware, including Taper Plus and AutoCAD. The crew efficiently creates CAD-generated set up store drawings starting from fundamental tapered layouts to complicated tasks requiring quick turnaround time. Firestone Building Products is committed to offering correct and well timed tapered take-offs that encompass all important elements affecting proper drainage.

Also, moderately regrettably for Couvreur ramoneur historically produced XPS, the hydro fluorocarbons (HFCs) mostly used as blowing agents are way more damaging to the climate than these used with different rigid foam insulation boards. Some manufacturers speak of a transition to extra eco-pleasant foam insulation blowing brokers; that can be great information when it happens across the board! And credit where it is due, the “real” Styrofoam, as in the DOW Chemicals blue product, is now manufactured with HCFC blowing brokers which have 94% much less ozone depletion potential. As HFCs have a worldwide warming potential (GWP) that’s 1430 times worse than carbon, this actually does demonstrate how necessary it is to decide on rigid foam insulation boards very carefuly to reduce their environmental affect. All XPS panels aren’t equal!
