AluStar 70 is a three-chamber system that enables the production of very tight and energy-saving doors. It is recommended for buildings where thermal and acoustic insulation is particularly important. The frame and the leaf in this system are of equal depth, so that the door is leveled with the frame.
AluStar 70 windows allow you to achieve slim and durable structures with high thermal and acoustic insulation. In this system, there are models from the so-called hidden sash and smoke exhaust windows.
