Cold-Climate & Passive House Envelopes
Thermally Broken Systems for Extreme Sub-Zero Winters
Our cold-climate fenestration systems are engineered to eliminate thermal bridging, prevent condensation, and maintain superior insulation performance in extreme sub-zero environments. Certified for Passive House applications with U-values as low as 0.8 W/(m²·K), these systems are ideal for energy-efficient buildings in northern climates.
Key Features & Benefits
Thermal Break Technology
Multi-chamber polyamide thermal breaks with glass fiber reinforcement reduce heat transfer by 95% compared to standard aluminum.
Condensation Prevention
Warm-edge spacer systems and insulated glass units maintain interior surface temperatures above dew point, eliminating condensation risk.
Air Tightness
Triple-seal EPDM gaskets achieve air leakage rates below 0.1 cfm/ft² at 75 psf, meeting Passive House airtightness requirements.
Triple Glazing Compatibility
Accommodates triple-pane insulated glass units up to 44mm thick with argon or krypton gas fills for maximum thermal performance.
