Energy Efficiency Specifications

Our system for wood-aluminum windows is designed for passive houses. We pay special attention to the high strength and performance parameters. Excellent thermal and acoustic insulation, above-average air tightness, air permeability and resistance to wind load makes our windows perfect for modern construction with high energy-saving and low cost utility requirements.

Our Passiv collection meets the requirements set by the Passivhaus Institut for a passive house, ie Uw ≤ 0.80 W / (m2K) in combination with a triple glazing unit Ug = 0.7 W / m2K.

The system uses an innovative high-strength insulation material based on foamed PS, with parameters similar to wood. Due to its high stiffness, our system fasteners are mounted directly on it with bolts. Additional elements distinguishing the system from traditional wood-aluminum constructions are the widened main gasket, PE cord, additional middle gasket and the use of a warm Swisspacer Ultimate frame.
