The certified wood-aluminium ENERsign®primus large windows and lift and slide doors with barrier-free threshold combine first-class level of workmanship with a strucutral balanced construction. It also offers high air tightness, excellent thermal insulation values and reliable burglary protection.

The ENERsign®primus large windows and lift-and-slide doors is an eye-catcher for every home thanks to its sophisticated technology, the large glass surfaces possible and the narrow frame widths all round.

Due to the exact guidance at the top and bottom, even large sliding sashes can be opened and closed with ease. The ENERsign large windows and lift and slide doors set dimension standards with heights of 110 “ and overall widths of 432”.

Due to the slim aluminum cover profile, insulation on “zero frame view” is possible without thermal bridges.

Generally, on regular lift and slide doors, the most problematic areas are the transition between sliding sash and fixed element, as well as the threshold design. Here the tightness is decisive. Not so for the ENERsign Lift&Slide doors, through sophisticated special and customized solutions, especially for large elements, these problems do not exist with the ENERsign design.
