Pu Spray Foam Insulation

PU Spray Foam Insulation (Polyurethane Foam Sealant) is a high-performance, expanding aerosol foam designed for superior sealing, filling, bonding, and thermal/acoustic insulation. Formulated for both indoor and outdoor applications, this dual-mode expanding foam cures rapidly upon contact with atmospheric moisture to fill irregular gaps, deep cavities, cracks, and structural joints, creating a seamless, airtight, and water-resistant barrier.

Key Features & Benefits

• High Expansion & Filling Capacity: Yields up to 30 liters of expanded foam per 750 ml can, effectively sealing large voids, structural penetrations, and deep wall cavities.
• Superior Adhesion: Bonds strongly to a wide range of building materials including concrete, brick, masonry, lumber, plywood, aluminum, glass, plaster, and various metals.
• Fast Curing Time: Features a tack-free time of less than 10 minutes, allowing for quicker project completion and easy trimming, sanding, or painting once fully cured.
• Thermal & Acoustic Insulation: Delivers exceptional thermal efficiency to eliminate drafts and heat transfer while reducing sound transmission through walls, floors, and gaps.
• Dual Mode Application: Flexible application design allows usage with a straw adapter or a standard foam gun for precise metering and controlled expansion.
• Weather & Water Resistant: Seals out moisture, dust, pests, and air leaks to enhance overall building energy efficiency and structural comfort.

Common Applications

• Doors & Windows: Insulation and sealing around window frames, door jambs, and sub-frames.
• HVAC & Plumbing: Sealing pipe penetrations through walls, air duct joints, and HVAC wall sleeves.
• Construction & Renovation: Filling structural gaps, drywall joints, ceiling-to-wall junctions, and roof gaps.
• Acoustic Soundproofing: Noise reduction in partition walls, floor joints, and utility closets.
