Description
Passive House Certified Aluminum-Plastic Co-Extruded Tilt & Turn Windows | Uw ≤0.8 Ultra-Low Energy Efficiency Windows
Built for Net-Zero & High-End Green Building Compliance
Aligned with the world’s most rigorous passive house and green building standards—including LEED, BREEAM, DGNB, and PHI—this system-level aluminum-plastic co-extruded tilt & turn window series delivers a complete building envelope energy-saving solution for ultra-low energy and net-zero carbon projects. Engineered with a full-dimensional closed-loop envelope system, the product meets the Uw ≤0.8 ultra-low energy consumption threshold, delivering industry-leading extreme energy efficiency, high-performance thermal insulation, and root-cause anti-condensation performance. Designed to help projects achieve carbon reduction targets and secure green building certifications seamlessly, these windows are the ideal choice for premium sustainable developments prioritizing long-term environmental and operational value.
Dual Thermal Insulation Barrier: Passive House-Level Thermal Performance
At the core of the window’s performance is a dual-structure thermal insulation system, clearly visible in the cross-section design. Combining a 34mm custom-shaped PA66 thermal break strip with a built-in 4mm nano-micro foaming thermal insulation layer, this dual barrier maximizes heat conduction blocking paths, fully eliminating profile cold and heat bridges. The nano-micro foaming layer forms a continuous, non-breakpoint closed thermal insulation cavity, working in tandem with the PA66 strip to block heat transfer at the profile matrix level. This passive house-grade design balances the full-section temperature of the profile, eliminating internal and external surface temperature differences that cause condensation. By preventing condensation-related envelope corrosion and indoor mold growth, the windows meet the stringent indoor air quality and building durability requirements of global green building standards.
Closed-Loop Full-Life Sealing System: Zero Cold Bridges & Condensation Elimination
To sustain long-term thermal performance, the window features a full life cycle closed-loop sealing system, using automotive-grade EPDM soft-hard co-extruded composite rubber strips that maintain seamless, stable sealing throughout the product lifespan. Achieving passive house-grade extreme air tightness, the system completely blocks hot and cold air convection and moisture penetration, further optimizing the window’s overall thermal performance. Every profile cavity is fully filled with thermal insulation closed-cell sponge, cutting off all-directional sound and heat transmission and eliminating internal cavity convection. This creates a fully enclosed moisture-proof and thermal insulation system, removing all environmental conditions for condensation generation and delivering system-level anti-condensation assurance critical for passive house and green building projects.
Triple-Glass Dual-Cavity Inert Gas Insulating Glass: Ultra-Low Heat Loss
Standardly equipped with three-glass two-cavity inert gas insulating glass, the window drastically weakens heat radiation and conduction through the glass component, minimizing overall window heat loss to reinforce ultra-high energy efficiency. This design enables all-season constant-temperature thermal insulation and extreme energy savings, significantly reducing the design load and operational energy consumption of the building’s HVAC system—core requirements for passive house ultra-low energy consumption. The glass structure also balances surface temperatures to fundamentally solve glass condensation issues, working with the overall system design to ensure zero cold bridges and zero condensation across the full window section, even in extreme climate conditions.
