Windows ®

Approved partner Keller Minimal Windows

The minimal windows® sliding systems offer maximum energy efficiency thanks to the optimized thermal insulation of the profiles and the use of large thermal protection glazing.

 

You can choose between double glazing or triple glazing, or even single glazing for unheated systems.

With triple glazing and depending on the dimensions of the structure, the minimal windows®4 + systems already achieve insulation coefficients worthy of a passive house with Uw values ≥ 0.70 W / m²K.
