UltraSeal PF-50 All-Weather Straw Foam is a single-component, low-expansion polyurethane foam designed to perform in even the most demanding job-site conditions. Engineered for all-weather use, it applies effectively in temperatures as low as -18°C, making it ideal for year-round sealing on Canadian job sites. The convenient straw applicator requires no dispensing gun, giving you precise bead control right out of the can. PF-50 bonds to virtually all common construction substrates — wood, metal, concrete, brick, stone, and most plastics — and is safe for use around Romex, PVC, PEX, CPVC, and rubber insulation. Use it to seal around windows and doors, fill gaps and cracks, and close off unrated pipe and duct penetrations. GREENGUARD Gold Certified and water resistant, UltraSeal PF-50 is the reliable, low-mess solution for air sealing that helps improve energy efficiency on every project.
