Standard Specification for Spray-Applied Rigid Cellular Polyurethane Thermal Insulation
STANDARD published on 1.1.2025
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the types and physical properties of spray applied rigid cellular polyurethane intended for use as thermal insulation. Spray-applied rigid-cellular polyurethane thermal insulation shall be classified into four type: Type I; Type II; Type III; and Type IV. Spray-applied rigid-cellular polyurethane thermal insulation shall be produced by the catalyzed chemical reaction of polyisocyanates with polyhydroxyl compounds and by the catalyzed polymerization of polyisocyanates. The following test methods shall be performed: thermal resistance; compressive strength; water vapor permeability; water absorption; tensile strength; response to thermal and humid aging; closed cell content; and surface burning characteristics.
