In times of high energy costs, roof panels with a highly heat-insulating core of polyurethane rigid foam are the first choice. With two layers of hot-dip galvanised and plastic-coated sheet steel and the PU insulating core, this roof panels also meet the highest standards in moisture protection. Additional benefits which stand out are high rigidity and load capacity allowing more distance between supports. In addition, the combination of long panel lengths and low weight facilitates economic construction. Convincing arguments: simple and quick assembly outstanding thermal insulation triple sealing system easy assembly connection principle module width 1,000 mm wide beam and support spacing panel lengths up to 24,000 mm.
Besides the superb solidity and durability with a beautiful appearance, the hard polyurethane resin foam used for panels performs quite well in heat insulation.
Globally, about half the energy used in the life of a building is for heating and cooling, so effective insulation is a major priority.Compared to other building materials, polyurethane insulation has the highest thermal resistance(R-values) at a given thickness and lowest thermal conductivity.
Use of polyurethane insulation products in residential and commercial buildings helps meet advanced energy codes, contributes toward gre
en building certifications and provides comfort to the building occupants.
