1、As trusted aluminium bi fold door manufacturers, our Bi-folding Doors' aluminum alloy profile adopts a multi-chamber PA66 thermal insulation design—aluminium bi fold door manufacturer prioritizes this advanced thermal insulation structure—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—an innovative detail that sets leading aluminium bi fold door manufacturers apart. Our aluminium bifold glass doors integrate this design to blend functionality with visual appeal.
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—aluminum glass bifold doors benefit from this optimized roller system for seamless use.
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.
Bi-folding door as a creative choice for home spaces, break through the limitations of traditional door types with their unique folding design—aluminium bi fold door manufacturer specialize in crafting such innovative door solutions.
When opened, the door panels fold in an orderly manner, instantly expanding the spatial view and seamlessly connecting indoor and outdoor spaces, adding a sense of openness and atmosphere to the home; our aluminium bifold glass doors excel in this space-integrating advantage. When closed, it tightly guards every inch of space and has good sound insulation, heat insulation, and moisture resistance performance. With its versatile design and flexible opening and closing methods, aluminum glass bifold doors perfectly adapt to various scene needs.
When browsing aluminium bifold doors for sale, it is easy to get distracted by the glass. However, the engineering of the frame dictates the door's longevity.
At Jolong, we don't just use "metal." We utilize 6063-T5 architectural-grade aluminium.
The Expertise: This specific alloy includes magnesium and silicon and is heat-treated (tempered).
The Benefit: It offers a superior strength-to-weight ratio. This allows for ultra-slim profiles that can still support massive, heavy panes of glass without bowing or warping over time—a common issue with lower-grade extrusions.
Historically, metal doors were poor insulators. That changed with Thermal Break Technology. High-end systems utilize a reinforced polyamide bar inserted between the inside and outside aluminium profiles. This creates an insulated barrier that stops heat transfer, ensuring your aluminum glass bifold doors keep warmth in during winter and heat out during summer.
Pro Tip: Always check the U-Value (insulation) and SHGC (Solar Heat Gain Coefficient). A lower U-value means better insulation.
One of the most common questions we face during the consultation phase is the choice between folding and sliding configurations. To make the right decision, you must compare aluminium bifold and sliding doors based on your structural opening and usage.
100% Opening: Bifolds can fold back completely against the wall, revealing roughly 90-95% of the opening.
Traffic Flow: Perfect for entertaining, creating a true seamless flow between a kitchen and a deck.
Unobstructed Views: Even when closed, sliding doors have fewer vertical frames (sightlines) breaking up the view.
Space Saving: They do not protrude onto the balcony or into the room, making them ideal for narrow spaces.
The Verdict: If you have the stacking space and want to "remove the wall," choose bifolds. If you have a narrow balcony or prioritize the view when the door is closed, opt for sliders.
When investigating aluminium bifold glass doors, the difference between a budget product and a premium investment lies in the hardware.
Many generic kits are "top-hung," meaning the weight of the heavy glass hangs from the top beam. Over time, this can cause the header to sag, making the doors stick.
The Jolong Standard: We utilize a stainless steel bottom-rolling system. The weight rests firmly on the floor track—the strongest part of the opening—ensuring a smooth glide for 20+ years.
Glass makes up 85% of the door. Ensure your manufacturer offers:
Double or Triple Glazing: Essential for soundproofing and thermal efficiency.
Low-E Coatings: Microscopically thin layers that reflect infrared heat without blocking light.
Modern aluminum glass bifold doors should feature multi-point locking systems (locking at top, middle, and bottom) and "anti-lift" blocks that prevent intruders from lifting the door panels out of their tracks.
There is a distinct advantage to sourcing directly from aluminium bi-fold door manufacturers rather than third-party retailers.
Cost: You bypass the middleman markups.
Customization: You get direct access to engineering adjustments, such as specific threshold heights (flush thresholds for accessibility vs. weathered thresholds for rain protection).
Accountability: As the manufacturer, we control the quality of the billet, the precision of the mitered corners, and the final assembly.
