Spray Foam Insulation
Spray foam insulation is a foaming insulation that is sprayed. This special type of insulation not only insulates but air seals wherever it is applied. Depending on what type of insulation used, closed-cell or open-cell, the foam can expand between 40 to 100 times its size upon application.
As products develop over the years, numerous different types of spray foam insulation have come forth. More often than not in residential and commercial jobs, open-cell and closed-cellular spray foam is used. High-density spray foam insulation is used as roofing foam in commercial or industrial construction. Open-cell sprayed-in foam insulation is commonly used for interior applications consisting of wall cavities, underside of roof decks, attics, basement walls and crawl spaces. The open cell structure of low density foam insulation permits for moisture permeability which helps contribute to moisture control and bi-directional drying of the wall assembly.
Closed-cell spray insulation, a rigid medium-density material, may be used in outdoor applications which include continuous insulation applications, in addition to indoor applications. This kind of foam insulation has a higher R-value per inch making it better for small areas that require the highest possible R-value to meet building code requirements. Closed-cell spray foam’s rigidity helps repel bulk water making it a recognized flood-resistant material by FEMA.
Benefits of Open-Cell Spray Foam
As previously mentioned, open-cell spray foam is best used on the interior of a structure. This offers several advantages over traditional fibrous insulation products. Here is a list of the benefits of open-cell foam:
-Allows for bi-directional drying
-Can be installed at a much lower cost and target the same R-value
-Not considered a breeding ground for mold
-Provide noise cancelling qualities, ideal for media or theater rooms
-Lower installed cost, per square foot
Benefits of Closed-Cell Insulation Foam
While the advantages of open-cell insulation are much greater than traditional types, closed-cell sprayed-in insulation goes far beyond to supply additional benefits. Although closed-cell spray insulation foam contains a higher per foot measure cost, there are advantages that the material offers including:
-Able to reject bulk water
-Can be applied at very cold temperatures
-Adds wall strength and impact resistance
-Higher R-value per inch, easier to accommodate high R-value requirement in small spaces
-Lower vapor permeance
-Higher bond strength
Spray Foam Insulation R-value
R-value is the thermal resistance measure of insulation. This value varies between all insulation products whether they are cellulose, fiberglass, open-cell spray foam or closed-cell spray foam insulation. The general rule of thumb is the higher the R-value, the greater the insulating power. Although open-cell has a lower R-value than closed-cell spray foam, both offer superior and consistent thermal insulation and air sealing properties.
