- Utilizes high-durability foamed PS insulation, closely resembling the properties of wood.
- The material’s rigidity allows for direct attachment of Gemini assembly clips, enhancing structural integrity.
2. Enhanced sealing components
- Incorporates a broadened main gasket, PE cord, additional central gasket, and the Swisspacer Ultimate warm edge spacer bar.
- Improves thermal performance and airtightness.
3. Advanced corner connections
- Features welded corner joints with “invisible weld” technology, ensuring a smooth, uniform surface and superior durability.
4. Versatile design options
- Compatible with Classic and Soft Line aluminum window sills.
- Offers the option to integrate the Gemini Insecta system frame mosquito net and the Gemini IGB balustrade into the cladding.
5. High-performance glazing
- Accommodates triple-glazed units with Ug values as low as 0.7 W/m²K.
- Achieves Uw values below 0.80 W/(m²K) in cool-temperate climates.
Advantages of GEMINI Passiv
1. Superior Thermal Insulation
- Provides excellent thermal performance, reducing energy consumption and ensuring a comfortable indoor environment.
2. Enhanced Airtightness and Wind Resistance

The GEMINI Passiv wood-aluminum window system blends advanced technology and design, making it an excellent choice for passive housing and energy-efficient buildings. Its superior thermal insulation, airtightness, and durability ensure long-term performance and comfort.
The system utilizes innovative insulation material of high durability foamed PS, which shares the properties of wood. Thanks to its high level of rigidity, Gemini assembly clips can be screwed directly into it. Additional components that distinguish this system from more traditional wood-alu designs include the broadened main gasket, PE cord, additional central gasket, and the use of a Swisspacer Ultimate warm edge spacer bar.
Features:
- Welded corner connections
- Crimped corner connections
- Certified wood section thickness 68 – 92 mm
- Certified glazing thickness 24 – 44 mm
- Acoustic insilation 32 – 45 dB
- Thermal transmittance 0,76 – 0,61 W/m2K
- Security class to RC1, RC2
Gemini Passiv, as a certified component of Passivhaus Institut, meets its requirements for passive housing. That is Gemini Passiv Uw < 0.80 W/(m²K) in combination with triple-glazing Ug = 0.7 W/m²K for cool-temperate climate and Gemini Passiv Ultra Uw installed Uw < 0.80 W/(m²K) in combination with triple-glazing Ug = 0.52 W/m²K for cold climate.
Bertrand uses the most advanced varnishes for wood.Our AQUATOP varnish, which we use as standard, protects surfaces from the weather and gives them a smooth and long-lasting protection.
AQUATOP is characterized by excellent moisture resistance.It protects surfaces from water, rain and moisture, preventing problems such as rot, mold and damage that occurs over time.It provides reliable resistance all year round, in any climate.
Thanks to advanced and innovative varnishes and a careful manufacturing process that is a hybrid of automated sanding of flat surfaces and manual sanding of hard-to-reach surfaces such as the area inside the frame, our wood windows feature a smooth and flawless finish.
Bertrand wood windows are perfect for hot climates thanks to the use of cold pigmented varnish.
