The R-value of spray foam insulation ranges from 3.5 to 7 per inch thickness. For open-cell spray foam the R-value is approximately 3.5 whereas for closed-cell spray foam it is 6. Spray foam insulation thickness. The thickness required for spray form insulation when insulating, for eg; an attic, depends on the R-value required for that place.It has been known for many years that a SPF (spray polyurethane foam) roofing system can enhance the wind uplift resistance of a roof covering. Field observations of ccSPF performance . (Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference) testing ASTM D7425 was developed to simplify and clarify requirements for SPF used as a roofing material. Some would argue that SPF is used in a roof system as insulation; therefore, a standard for SPF as thermal insulation is adequate. Others believe that because SPF also is used as a roof membrane, a standard for SPF used in roofing is needed.
SPF Roofing: All roofing systems used in residential construction must be rated class A, B, or C in accordance with UL 790 (or ASTM E 103) The A, B, or C designation is an indicator of how far the flame front travels across the sample during the test (A being the best).thickness of 5 ½ inches yields an R-value of about 17.8. The ICC-ES report for Insulstar spray foam from NCFI (ESR-1615, issued February 1, 2005) lists a maximum thickness of only 2 inches: “Insulstar Spray Foam Insulation is a spray-applied, semi-rigid, cellular polyurethane foam plastic insulation
In previous years, SPF suppliers most often recommended a maximum lift thickness of 2 inches or less. The sample preparation in ASTM C1029 was based on maximum lift of 2 inches thickness. Now, many suppliers have foams with recommended lift thickness greatly exceeding 2 inches, one even recommends up to 8 inches.ROOFING FOAMS Energy Efficient for more Energy Savings. Find Out More.

Given the importance of this material’s performance, quality control measures should be set in place. Some key issues include moisture content and temperature of the substrate, applied spray foam layer or “lift” thickness, ratios of the two spray foam components during application, and storage/handling of spray foam components. When a roof is low and can be accessed easily with a lift from outside or from stairs inside, time is reduced – and cost is too. . Foam Thickness. SPF foam is an effective way to add insulation value to any building. With an R-value (resistance to heat transfer) of 6.6 per inch, R-10 can be added to the roof with 1.5 inches of spray foam .

The following four types of SPF blisters are most frequently encountered: Type A. Interlaminar–Top Lift: A separation between the top layer or lift of the SPF and the lift beneath it. These are generally small in size, typically 50–300mm (2 inch–1 foot) in diameter. They are easily broken when touched or stepped on.thickness of the foam plastic applied to the underside of the overhead surfaces (roof sheathing, rafters and the underside of floors) must not exceed 71/4 inches (184 mm). The thickness of the foam plastic applied to vertical surfaces must not exceed 111/4 inches (286 mm). The attic or crawl space must be separated from the interior of the Typical ccSPF interior wall or ceiling insulation systems entail application of spray foam at a nominal density of 32 kg/m3 (2 pcf) onto a properly prepared surface—clean, dr, and free of contaminants—in multiple lifts averaging approximately 25 to 50 mm (1 to 2 inc.) in thickness per lift.
