Description
Thanks to the increased profile width and the 4-chamber construction of frame and sash profiles, the Profine 70 mm FT Plus window profile has improved thermal insulation properties that meet modern European energy-saving standards. Windows made from the Profine 70 mm FT Plus profile combine functionality, convenience, and absolute safety. The wide profile allows for better insulation of the gap between the window and the wall during installation, which is an important factor in retaining warmth in the room. KBE window and door structures are designed for glazing residential and administrative spaces.
