WebThis is foil-faced polyisocyanurate; the R-value of ISO decreases over the years. R-values for rigid insulation vary from R-3.85 to R-6.8 per inch of thickness. Polyiso has the highest R-value, followed by XPS and EPS. The key to all rigid insulation high R-values are small air pockets that exhibit high thermal resistivity properties: WebPolyiso rigid foam or polyiso foam board. In the industry, we refer to these boards as ISO boards. ISO boards have a thickness from 0.5 inches to 2.5 inches, with a corresponding R-value of R-2.9 to R-14.5. Polyiso insulating …
WebDuPont ™ Thermax ™ Sheathing is a multipurpose, nonstructural, rigid board insulation that is quick and easy to install in a wide range of exposed and concealed cavity wall applications. It consists of a glass-fiber-infused polyisocyanurate foam core laminated between 1.0-mil smooth, reflective aluminum facers on both sides. WebProperly installed rigid foam board provides a layer of protection against moisture. Enhanced R-value: With a long-term R-value from 3 to 5 or higher per inch, rigid foam insulation boards can increase the R-value of the entire wall, covering wood studs and other parts of the wall, such as framing, ducts, wiring and plumbing.
WebPolystyrene is basically a lightweight building material that is not very dense. At its best, polystyrene has a sound absorption rate of 0.20. EPS is most effective when you use it along with other materials and in itself performs better at attenuation of mid-upper sound frequency. The NRC of polystyrene 25 is 0.59 at a sound frequency of 2500.
