Model S40: High Insulation Performance
All our S40 burglar-resistant sectional doors are made of 40 mm thick steel sandwich panels that slide seamlessly into one another.
These panels are coated on both sides with steel sheets and filled with fire-retardant polyurethane foam (CFC-free), providing top-tier insulation values according to European standards and significantly reducing your energy consumption.
The U-value of this panel is 0.561 W/m²K.
Dimensions of the CR4 or CR3 Sectional Door
All CR3 and CR4 sectional doors are fully custom-made, then assembled and installed on-site by our network of specialized and experienced installation partners.
The wide range of available dimensions is defined by the CR3 and CR4 test certificates, with a maximum surface area of 45 m².
All details regarding the minimum and maximum standard dimensions are available in our technical data sheet.
Finishes of the CR4 or CR3 Sectional Door
While security remains our top priority, we also pay close attention to the aesthetic aspect of our burglar-resistant sectional doors.
Depending on the selected panel model, you can choose from up to 18 standard RAL colors for the exterior powder coating of your door. By default, the interior side is always finished with galvanized steel sheeting.
Upon request, both the interior and exterior surfaces of the burglar-resistant sectional doors can be powder-coated in any RAL color of your choice.
