the better the insulation value. Closed-cell spray foam has an R-value of about 6.0 per inch (R-6), while open-cell SPF comes in at roughly R-3.5. (Note: these R-values are rough averages. Every SPF product will vary based on its formulation.) ...
Closed-Cell SPF At 2-lbs per cubic foot closed-cel l SPF,alternately cal led 2-lb foam, is approximately four times denser than open-cel l foam.Once set, the material remains rigid and more difficult to compress by hand-appl ied pressure. In compression closed-cel l is ten times strong...
WALLTITE®is a closed-cell spray polyurethane foam (SPF) insulation that creates a seamless, insulating air barrier to improve the energy efficiency, comfort and durability of homes and buildings. Spray applied as a liquid, WALLTITE flows in and around difficult to reach areas, creating a air...

Open cell spray foam insulation is cheaper per unit of R-value than closed-cell foams. Open cell does not provide all the features that closed cell foams do. Open cell foams are lower in R-value (3.8 vs. 7.0). Open cell foams have tremendous sound attenuating properties (STC 38 in a ...
