The door leaf has a thickness of 40mm and a U value of 1.77 W/m2K (for door size 5000 x 5000mm with ISO panels). Aluminium sections can be supplied as glazing elements on request. With the service kit for quick and smooth repair of the running rails, Alpha Deuren has fulfilled a frequently expressed customer request. The previously vertical running rails on the door have been replaced by split vertical running rails especially for this purpose. The lower part corresponds to the height of the three lower panels, as these are often hit in case of a collision. The built-in plastic and metal clips can be dismantled, so that the chain guide can be removed and the repair can be completed in a short time. The service kit contains plastic and metal clips, a service tool, chain guide block and the lower part of the track (left and right). The Helix service kit is also competitively priced and the replacement of spare parts takes less time than before. The revised and improved Helix door has been available without extra charge since the beginning of September.
