PU Foam Insulation
PU Foam Insulation
Green Insulation Private Limited (sister concern of Petroseal Enterprises) supplies polyurethane foam insulation (PUF)—rigid boards and spray-applied systems. PUF is thermal insulation only (not a waterproofing coating). High R-value per inch suits roofs, walls, and cold rooms nationwide. Petroseal coordinates specification with PetroGrip waterproofing above the insulation layer.
Key features
- — High R-value per unit thickness—thinner assemblies vs. bulkier boards
- — Closed-cell structure with low moisture absorption
- — Rigid boards for roofs, walls, and under-deck applications
- — Spray PUF option for seamless coverage on irregular substrates
- — Compatible with waterproofing and membrane build-ups above
Applications
- Insulated concrete and metal deck roofs
- Wall and cavity continuous insulation
- Cold rooms, chillers, and process buildings
- Retrofit overlays where height is constrained
