Description
SGS F850 High-Yield Polyurethane Expanding Foam (850gm)
Achieve superior insulation and airtight seals on your construction projects with the SGS F850 Polyurethane Expanding Foam. A highly versatile staple in the Afrogulf building materials catalog, this professional-grade PU foam is formulated to expand and quickly fill deep, irregular gaps where standard caulks and sealants simply cannot reach. Whether you are installing heavy commercial door frames, sealing drafty window units, or filling large voids around plumbing penetrations, this foam provides a permanent, structural, and weatherproof barrier.
The major advantage of the F850 model is its high-capacity 850-gram volume, offering an exceptional expansion yield that contractors rely on to minimize the number of cans needed per job. Once dispensed, the foam aggressively expands to fill the exact shape of the cavity, curing rapidly into a dense, semi-rigid cellular structure. This cured foam not only provides outstanding thermal and acoustic insulation but is also incredibly easy to work with—it can be easily cut, trimmed, sanded, and painted over to deliver a clean, flush, and professional finish.
Key Features & Specifications:
-
High Expansion Yield: The large 850gm capacity produces a massive volume of cured foam, making it highly cost-effective for large-scale gap filling and framing jobs.
-
Thermal & Acoustic Insulation: The dense cellular structure significantly blocks heat transfer and reduces sound transmission between rooms or from the outdoors.
-
Superior Adhesion: Bonds strongly to almost all common construction materials, including concrete, brick, plaster, wood, metal, and PVC.
-
Workable Cured Finish: Once fully cured, the excess foam can be easily sliced with a utility knife, sanded smooth, and painted or plastered over for a seamless look.
-
Weather & Pest Proof: Creates an airtight, moisture-resistant barrier that effectively keeps out drafts, water seepage, and unwanted pests.
Applications: Highly recommended for mounting and insulating window and door frames, sealing gaps around air conditioning ducts and plumbing pipes, filling deep cavities in masonry walls, and general roofing or attic insulation.
