Heavy-Duty Thermally Broken Aluminum Bi-Fold Windows

Heavy-Duty Thermally Broken Aluminum Bi-Fold Windows Overview | BLOSSOM CHEER

Engineered for low-energy buildings, our thermal break bifold windows combine PA66 GF25 struts and Low-E glazing to optimize U-factors, cut HVAC costs, and stop interior condensation.

Key Benefits of Thermally Broken Aluminum Bifold Windows | BLOSSOM CHEER

PA66 GF25 Multi-Chamber Struts Achieving U ≤ 1.4 W/(m²·K)

Precision polyamide thermal breaks interrupt conductive heat bridging, lowering operational HVAC cooling and heating costs.

Heavy-Duty 4-Roller Carriages Supporting 120kg Oversized Sashes

Reinforced top-hung carriers glide smoothly along extruded alloy tracks, supporting heavy triple IGUs without structural sag.

Aligned Isothermal Plane Design Preventing Sweating at -25°C

Continuous isothermal alignment stops cold bridges, keeping interior frames dry and mold-free during severe sub-zero winter spells.

Triple Low-E Argon-Filled IGUs Delivering STC 38 Sound Barrier

Multi-chamber profiles paired with argon-filled Low-E glazing isolate street noise, protecting acoustic comfort in public venues.
