G3 120 mm, roofing sandwich panels
PUR or PIR roof sandwich panels - G3.
Terms and conditions
- The outer and inner cladding are made of galvanized steel sheet, coated with 25 µm PE (polyethylene) in a rich color palette.
- Cladding profiles: trapezoidal, grooved, linear, micro profile and smooth.
- The core of the sandwich panel is made of hard foam with excellent thermal insulation parameters. Depending on the needs, PUR polyurethane foam or PIR polyisocyanurate foam with increased fire resistance is used.
- Modular width 1000 mm.
- Easy and fast thanks to the labyrinth lock, which at the same time plays the role of a good insulator and in addition to system accessories is simple to use.
Use of 120 mm thickness:
Sandwich panels with a thickness of 120 mm are intended for covering roofs with a slope of more than 7% for office buildings, public utilities, industrial buildings, workshops, storage, agricultural. They work well in buildings with increased thermal insulation requirements, maintaining a stable temperature inside the building. They can be used in cold stores that do not require low temperatures.
