Classic-Therm® GFK Standard

External layer - GFK sandwich panel

– polyester-glass laminate with a smooth surface with slightly visible embedded glass fiber, while good resistance to UV radiation and weather conditions
– the following basic raw materials are used for the production of the laminate:
– resins (binding components);
– glass fleece – improves the surface optics;
– glass mat – determines the mechanical properties;
– glass fabric – provides significantly greater reinforcement in both directions
– panel thickness tolerance +/- 1.0mm
– the permissible value of deformation of the panel cladding is max. 5mm
– the manufacturer does not recommend varnishing or covering the GFK cladding surface with dark colors

Inner layer - XPS core

– extruded polystyrene – hard foam without CFCs
– thermal conductivity group 035
– compressive strength 0.30 N / mm2 according to DIN 53421
– water absorption after 28 days <0.7% according to PN-EN 12087 + A1
– flammability class E
– apparent density 30-33 kg / m3
– temperature range -60 / + 70 ° C
