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...
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 spray foam insulation is a high-density insulation that provides greater resistance to water vapor than open cell spray foam. Its tiny foam cells are closed and packed tightly together. When filled with gas, the foam rises and expands to become a greater insulator. It is used on...
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 ...
Low temp. insulation consists of 2 layers, one of open cell and one of closed cell polyurethane foam, the former being situated on the side at lower temp., partic. in contact with a cold liquid. Used for transport and storage vessels contg. liquids at temps. well below ambient and at ...
PROBLEM TO BE SOLVED: To provide an open-cell foamed body made of polystyrene resin that has excellent recyclability with easy handleability, high foaming magnification, weight lightening, thermal insulation, air permeability and moisture permeability. SOLUTION: The objective open-cell foamed body compri...
