80 Series thermal break Bi-fold Doors

1. The aluminum alloy profile adopts a multi-chamber PA66 thermal insulation design, effectively reducing heat conduction and enhancing the overall thermal insulation performance of the window.
2. The folding opening mechanism features a postless corner design for maximum opening space, offering an uninterrupted, expansive view.
3. The multi-chamber isobaric sealing strip design, combined with EPDM foam composite sealing strips, achieves a three-layer seal for superior thermal insulation, soundproofing, and energy efficiency.
4. Concealed hinges and roller components contribute to a stylish, elegant, and sophisticated appearance.
5. The middle mullion is reinforced to enhance wind resistance, ensuring balanced stress distribution across the entire door panel to prevent sagging.
6. The upper part of the door panel incorporates a spring-damped sliding wheel, while the lower part uses a support-type multi-roller design paired with stainless steel tracks. This ensures that folding and sliding operations are lightweight, smooth, and efficient.
7. For friction-prone areas between the frame and sash, TPE3 composite sealing strips (co-extruded soft and hard materials) are used, with a surface treated with low-friction materials. This combination significantly improves sealing performance while delivering quieter and smoother operation.
8. The door is designed with an anti-pinch mechanism to ensure the safety of you and your family.
9. Equipped with a drip board for smooth drainage, effectively preventing leaks.

Incorporating electrostatic powder coating surface treatment, with a quality guarantee of 7 years.
