Plastic balcony door 3500x2100 mm With right side window

The REHAU SYNEGO profile system has 7 chambers in the frame and 6 chambers in the sash for increased thermal insulation. 3 sealing contours reliably protect against drafts and moisture. Old windows are the biggest source of heat loss in a home. They poorly insulate and are usually technologically outdated. As a result, valuable heat is lost through the windows. Thanks to the excellent thermal insulation properties of the SYNEGO system, you can reduce energy costs. Exclusive design options are possible, such as lamination or an external aluminum overlay on the profile, painted in different colors, glass panes, or decoration of the double-glazed units. There is also a fairly large selection of colors and types of window handles with anti-burglary fittings on the hinges.
