Double Casement Window
Engineered to redefine home energy efficiency, our double casement windows combine rigorous certification standards with innovative thermal engineering. Featuring NFRC-certified IGCC glass units delivering industry-leading U-values of 0.2-0.3, these windows outperform conventional models by 40% in thermal retention. The 35.3mm super-wide thermal barrier system, reinforced with dual-density insulation wool and isothermal frame alignment, creates a complete thermal break solution for extreme climates.

Key Features of Double Casement Windows
1. Advanced Energy Efficiency
– IGCC-certified glass paired with a 0.27 U-factor and 0.17 SHGC ensures optimal thermal performance, reducing heating/cooling costs by up to 30%.
2. Ultra-Wide Thermal Break Design
– 35.3mm insulated barriers + foam-filled frames create a “thermal block” to minimize heat transfer, outperforming standard windows.
3. Reinforced Corner Joints
– Pre-injected corner brackets + waterproof adhesive technology enhance structural stability and prevent air/water infiltration.
4. Triple-Layer EPDM Seals
– Weather-resistant EPDM gaskets retain elasticity in -40°C to 120°C, ensuring lifelong airtightness (0.02 L/s·㎡ airtightness).
5. Globally Certified Reliability
– Tested to AAMA CW, NFRC, CE, and CSA standards for hurricane resistance (5000Pa) and extreme weatherproofing.
6. Customizable & Low Maintenance
-Durable powder-coated frames + easy-clean tilt sashes adapt to any architectural style with minimal upkeep.
