The highly insulated Teckentrup sectional doors SW80 are particularly suitable for (refrigerated) warehouses in the food sector. The energy usually required to maintain a constant temperature inside these buildings is exceptionally high. The double-skinned, 80 mm thick, thermally separated steel panels as well as the circumferential, rot-proof special seals help to achieve the extremely low UD value of just 0.58 W/m²k. The heat or cold loss is minimized, and energy costs drastically reduced. And due to its great stability, the special door is particularly suitable for windy areas (e.g. in mountainous or coastal regions).
