Products / QUIK-SHIELD 155

QUIK-SHIELD 155 is a closed-cell, two-component, spray-applied polyurethane roofing foam that forms a self-flashing, seamless roof layer without mechanical fasteners. It is sold in three density grades, 155-2.5, 155-2.8 and 155-3 (labelled 2.5, 2.8 and 3.0 lb roofing foams), each in winter, intermediate and summer blends, with an HFC-free, low global warming potential blowing agent. SWD's data sheets list 50 psi compressive strength (ASTM D1621), over 90% closed-cell content (ASTM D6226), wind uplift of 160 psf on wood and concrete decks and 165 psf on metal decks (UL 1897), and an aged R-value of 5.7 at one inch. ICC-ES report ESR-2532 evaluates it as part of coated foam roof systems topped with QUIK-SHIELD 1929F coating, which reach Class A or Class B depending on the assembly (ASTM E108 / UL 790).
