Gun Foam Sealant DAP 812 26 oz

DRAFTSTOP® 812 Low-pressure/non-rigid polyurethane foam is available in 26 oz gun grade and 16 oz Stop N' Store™ straw grade canisters. DRAFTSTOP® 812 is low-pressure single-component polyurethane foam designed to fill gaps between fenestration products and rough openings. It will provide an air-tight seal and protect against water, air and sound intrusion. The non-rigid, highly elastic foam has 30% joint movement capability which accommodates movement and settlement to maintain an air-tight, weatherproof seal. It is closed cell, minimal expanding foam which will not absorb water, warp or deflect window or door frames.
