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
