The GEMINI Passiv is a wood-alu system for window constructions designed for passive housing. Thanks to its high utility and durability in the form of excellent thermal insulation, above average tightness, air permeability and wind load resistance, this system is suitable for modern, energy-saving and high performance buildings.

GEMINI Passiv, as a certified component of Passivhaus In stitut, meets its requirements for passive housing, that is: Uw < 0.80 W/(m²K) in combination with triple-glazing Ug = 0.7 W/m²K.

The system utilizes innovative insulation material of high durability utilises on foamed PS, which shares the properties of wood. Thanks to its high level of rigidity, GEMINI clips can be screwed directly into it. Additional components that distinguish this system from more traditional wood-alu designs include the breader main gasket, PE cord, additional central gasket, and the use of a Swisspacer Ultimate warm edge spacer bar.
