Entrance door dedicated to energy-saving constructions. The 73 mm thick wing is filled with polyurethane foam. The warm door frame, in combination with the Roto aluminum threshold, thermal divider and four-sided rebate, ensures energy efficiency at the highest level. It is possible to order the XPS understructure to the threshold allowing for additional thermal insulation increase. Exterior doors are equipped with three 3D hinges with a diameter of 20 mm, which are characterized by the ability to carry heavy loads, which significantly increases the functionality and comfort of use. The entrance structure equipped with such a hinge does not tend to fall. In addition, the hinges allow adjustment in three planes, which ensures symmetry of the wing position relative to the frame (up / down and left / right adjustment), as well as the appropriate pressure of the wing against the frame (third adjustment plane). Two independent locks with three bolts and three anti-theft bolts ensure a high degree of burglary resistance.
