Our sandwich roof and wall panels can be categorized as fire resistant panels, as rockwool insulated, and polyurethane insulated panels.
Polyurethane insulated panels are made up of 3 main raw materials. Steel is the outer sheets of the material, wihich can be in diferent thicknesses and different colours. And the insulation material, polyurethane, is made up of two main raw material : ISO and POLY. The polyurethane insulation is very efective in heat insulation, however it is in B2 fire resistance class, which means it does not stand in fire, however it does not catch fire. Our wall panels have secret - fix detail, which enables the screws to be hidden.
If case of a fire resistance need in a project, rockwool insulated sandwich panels should be chosen, which stands 60 - 90 - 120 minutes, in fire. The time depends on the thickness of the rockwool insulation.
There are 2 main raw materials in a fireproof panel. One of them is again steel material, as the two outer layers of the panel, and between the sheets there's rockwool insulation. The thickness of the rockwool does not effect the heat insulation.
Also, polyurethane is a better choice in terms of heat insulation.
We are also producing cold storage panels between the thicknesses of 60mm ~120mm.
Also single sheet cladding materials, without insulation, are available in our production plant.
