Passive house lift and slide door: Masterclass of window construction

The most problematic areas with lift and slide doors are the transition between the sliding sash and the fixed element, as well as the threshold design. Here, the tightness is decisive. Sophisticated, special, and customized solutions are necessary, especially for large elements.

The ENERsign GmbH has acquired this know-how through years of experience and further development. The ENERsign^®primus lift and slide door is a sophisticated solution for passive houses, zero-energy houses, plus-energy houses, and KfW Efficiency Houses 40 and 40+.
