Download Spec Sheet

The Ultra-Thane Foam System is used as a nonstructural thermal insulating material for Class A or Class B roof coverings, and roofing recovers over existing classified roof systems. Roof coverings with an A or B classification, as noted in Table 1, are permitted on buildings of any type of construction.

The Ultra-Thane Foam System consists of the Ultra-Thane 230 Roofing Foam, a spray-applied polyurethane foam plastic, covered with Ultra-Flex 1000 or Ultra-Guard 5700, liquid applied, elastomeric coatings.

The Ultra-Thane 230 Roofing Foam consists of two components, “A” (isocyanate) and “B” (polyol resin), which are intended to be interacted in a one to one ratio, by volume, and spray-applied to form a closed cell rigid foam plastic roof covering/insulation material with a nominal density of 3 pounds per cubic foot. The A and B components are available in 55 gallon drums and have a shelf life of 6 months when stored at temperatures between 50°F and 80°F.
