Sandwich PUF Roof Panel is made by injecting Polyeurathane in between the top sheet and bottom sheet. The panel is made up of a Corrugated CGI,PPGI or S-Span Sheet at the top and a plain corrugated sheet at the bottom.  Sandwich PUF panels are widely used in the construction of prefabricated buildings.

These Sandwich PUF Panels are extremely lightweight, weather-resistant, and, environment friendly. These budget-friendly PUF panels are gradually decreasing the use of traditional construction materials like cement and bricks.


  • Energy-efficient and durable Panels.
  • Suitable for diverse applications.
  • Can withstand wind velocity up to Maximum Level.
  • Can withstand heavy snowfall/rainfall.
  • It can withstand extreme temperatures from -50 degrees Celsius to +50 degrees Celsius.
  • PUF having a thermal conductivity of 0.018 Kcal prevents cross heat flow between room & outside ambiance.
  • Easy to Install with Screw down system same as any other Metal Sheet
  • These shelters are very light in weight, compact, and have high structural strength, making it possible to create a suitable size.
  • No air or water can penetrate through the panels of the shelter.
  • Durable Coating, Corrosion Resistant, Tamper Proof, and Water Proof.
  • Especially designed CROWN OVERLAPPING of the panel for 100% leak proof construction.
  • Highest strength as compared to simple roofing that will increase purling spacing and bring down the cost of the frame for installation.
  • Lightweight and extremely easy to install.
  • Aesthetically beautiful
  • Long life
  • Sound absorb because of sandwich PU foam insulation
