Closed-circuit construction
Both outer and inner steel sheets are interlocked at the top and bottom (where the 4-layer metal construction is fixed). It protects the panel from delamination in the sun (important for dark-colored doors and operation in south regions).Protection against finger trapping
Alutech panels comply with one of the main European safety standards: they eliminated finger trapping (comply with EN12604).Good adhesion of steel sheets and foam
Adhesive lacquer coating (of 12 microns) provides good adhesion of steel sheets and foam. So the design engineers have eliminated bubbling of the panel under the sun.Perfect anticorrosion properties
Primer and zinc layers of 14-16 and 16 microns ensure perfect anticorrosion properties of sandwich panels.Durablecoating
The external surface of a panel has a polyurethane coating with integrated polyamide particles (PUR-PA). It protects from scratches and increases overall resistance to corrosion.Optimalthermalinsulation
Optimal thermal insulation. Thermal transmittance of Alutech doors is 1,35 W/m²K.Microwave | S-ribbed | |||
