This is a warmer version of the Superior model. The entrance door is filled with injected PUR polyurethane foam, providing much higher thermal insulation parameters than expanded polystyrene. The door leaf structure is based on a frame made of high-quality, waterproof hardwood plywood - it ensures mechanical stability of the door leaf in changing weather conditions. The outer leaf is equipped with two locks with three pins and three anti-burglary pins. The energy-saving door frame prevents the formation of thermal bridges thanks to a special, two-part structure divided by a plastic insert - it is equipped with a thermal threshold of the same construction. Outdoor models are equipped with three 3D hinges with a diameter of 15 mm, making adjustment much easier. As in the case of the Superior package, you can order entrance models of a specific height - the factory-made shortcut allows the production of doors to size, without cutting the leaf and frame.
