2. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   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 ...

3. Building insulation material - Wikipedia

   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.

4. R-value (insulation) - Wikipedia

   en.wikipedia.org/wiki/R-value_(insulation)

   Loose-fill insulation comes in loose fibers or pellets and should be blown into a space. Rigid foam is more expensive than fiber, but generally has a higher R-value per unit of thickness. Foam-in-place insulation can be blown into small areas to control air leaks, like those around windows, or can be used to insulate an entire house. [33]

6. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   Grey polystyrene foam, incorporating graphite, has superior insulation properties. [45] Carl Munters and John Gudbrand Tandberg of Sweden received a US patent for polystyrene foam as an insulation product in 1935 (USA patent number 2,023,204). [46] PS foams also exhibit good damping properties, therefore it is used widely in packaging.

7. Rigid panel - Wikipedia

   en.wikipedia.org/wiki/Rigid_panel

   A multi-family residential building under construction with rigid panel exterior insulating sheathing. Rigid panel insulation, also referred to as continuous insulation, [1] can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR), and polystyrene, or from fibrous materials such as fiberglass, rock and slag wool.
