I-SPRAY PU Expanding Foam
High-expansion polyurethane foam for sealing, filling, insulation, and construction gaps
I-SPRAY PU Expanding Foam
๐๏ธ Professional Gap Filling with Strong Expansion Power
I-SPRAY PU Expanding Foam is designed for construction, renovation, installation, and maintenance work where reliable gap filling and sealing performance are essential. After application, the foam expands to fill cavities, cracks, joints, and hard-to-reach spaces, forming a durable structure that helps improve insulation, reduce air leakage, and support a cleaner installation finish.
Ideal for doors, windows, wall penetrations, pipe gaps, insulation areas, and general construction sealing, this polyurethane expanding foam delivers convenient aerosol application with strong adhesion and efficient coverage.
