Closed Cell Spray Foam Interior Applications

Closed-cell spray-applied polyurethane foam insulation is an air barrier material that can have an initial pass thickness of 5 inches. Closed-cell medium-density foam insulation is suitable for use in both exterior and interior applications.

• Can be applied at very low temperatures (as low as 5oF)
• Adds wall racking strength as well as impact resistance
• Ideal for continuous insulation solutions
• Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces
• Lower vapor permeance (can be a Class II VDR)
• Can reject bulk water (ideal for flood zones)
• Higher tensile and bond strength

Closed Cell Insulation is most often used in:

• Exterior walls as continuous insulation
• Wall cavities
• Floor assemblies
• Attics (vented and unvented)
• Crawl spaces (vented and unvented)
• Foundation walls on the interior or exterior
• Underfloor slabs
