Closed-cell foams are superior insulators. While open-cell foams typically have R-values of 3 to 4 per inch (RSI-0.53 to RSI-0.70 per inch), closed-cell foams can attain R-values of 5 to 8 per inch (RSI-0.88 to RSI-1.41 per inch). This is important if space is limited, because it allows a thinner layer of insulation to be used.
The claimed R-value of Styrofoam insulation is approximately 5 °F⋅ft 2 ⋅h/BTU for 1 inch thick sheet. [7] Styrofoam can be used under roads and other structures to prevent soil disturbances due to freezing and thawing. [8] [9] DuPont also produces Styrofoam blocks and other shapes for use by florists and in craft products. [10]
EPS is the most common of the foams used and has an R-value (thermal resistance) of about 4 °F·ft 2 ·h/Btu (equivalent to about 0.7 K·m 2 /W) per 25 mm thickness, which would give the 3.5 inches (89 mm) of foam in a 4.5-inch-thick (110 mm) panel an R value of 13.8 (caution: extrapolating R-values over thickness may be imprecise due to non ...
They are followed closely by polyisocyanurate (PIR) at R-5.8, graphite impregnated expanded polystyrene at R-5, and expanded polystyrene (EPS) at R-4 per inch. Loose cellulose, fibreglass (both blown and in batts), and rock wool (both blown and in batts) all possess an R-value of roughly R-2.5 to R-4 per inch.
Corner view of ThermaSAVE panel segment abut Completed ThermaSAVE panel awaits destructive testing.. ThermaSAVE is a panel building system which uses a 4 to 12-inch-thick core of expanded polystyrene (similar to Styrofoam) sandwiched between two sheets of cellulose fiber-reinforced cement board varying in thickness from 3/8 to 7/16 inch, depending on structural requirements.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
