Thermoseal 500 HY Spray-applied Polyurethane Insulation.
The insulation is a two-component, open-cell, spray-applied polyurethane foam plastic with a nominal density of 0.5 pcf. The insulation is produced in the field by combining a polymeric isocyanate (A component) with a resin (B component). The insulation liquid components are supplied in 55-gallon drums and must be stored at temperatures between 65°F and 85°F. The A and B components have a shelf life of six months when stored in factory-sealed containers at these temperatures.
The insulation meets the requirements of Mandatory Testing and selected Optional Testing of ICC-ES Acceptance Criteria for Spray-applied Foam Plastic Insulation (AC377), for a low-density insulation as described in Code Compliance Research Report CCRR-0415.
