Slimline Thermal Break Aluminium Double Glazed Bifold Doors
Architects and builders require glazing solutions that deliver wide unobstructed views without compromising structural integrity or thermal performance. Our slimline aluminium double glazed bifold doors are engineered for high-end residential and commercial projects.
Manufactured using extruded 6063-T5 aluminum with an integrated polyamide thermal break, these doors actively prevent heat transfer. This ensures compliance with strict energy codes in cold climates and reduces cooling loads in hot regions. With ultra-narrow sightlines and heavy-duty roller mechanisms, they provide smooth operation even at maximum custom sizes.

Core Engineering Advantages
- Thermal Break Technology: Incorporates a structural polyamide strut between the inner and outer aluminum profiles, drastically reducing thermal conductivity and eliminating interior condensation.
- Slimline Profiles: Engineered to support heavy double-glazed units while keeping the frame-to-glass ratio minimal. Sightlines are reduced to maximize natural light entry.
- Commercial-Grade Hardware: Fitted with multi-point locking systems and precision-engineered stainless steel rollers (brands including SIEGENIA or ROTO) for durable, secure operation over decades of heavy use.
- Custom Configurations: Available as custom size aluminium double glazed front doors, stacking doors, or corner-opening bifolds to match your specific architectural blueprints.

FAQ
Q: What is the Minimum Order Quantity (MOQ) for wholesale orders?
A: For standard profiles and colors, our MOQ is typically 10 sets or 50 square meters. For custom extrusions or non-standard RAL powder coating colors, the MOQ is 100 square meters.
Q: What is the standard lead time for custom size aluminium double glazed doors?
A: After shop drawing approval and deposit receipt, production time is 25–30 days. Shipping time depends on the destination port, typically ranging from 14 to 35 days.
Q: Do these doors meet building regulations for cold climates?
A: Yes. Our thermal break aluminium double glazed doors, when paired with Argon-filled Low-E glass, achieve U-values low enough to pass strict energy efficiency standards in North America, Europe, and Oceania.
Q: Can the aluminium profiles be matched to our specific project colors?
A: Yes. We offer AkzoNobel powder coating in any standard RAL color. We can also provide PVDF coatings for projects requiring enhanced UV and corrosion resistance, particularly in coastal areas.
Q: How do these slimline bifold doors perform against wind and water penetration?
A: Our frames utilize a multi-chamber design and automotive-grade EPDM gaskets. They are tested to withstand high wind loads and feature concealed drainage systems to prevent water pooling in the tracks during heavy rainfall.
Q: Is the hardware rated for heavy commercial use?
A: We use heavy-duty stainless steel top-hung or bottom-rolling hardware systems capable of supporting up to 120kg per door panel, ensuring smooth operation even for oversized commercial entrance doors.
Q: Is it possible to replace the glass if it breaks without dismantling the whole door?
A: Yes. The aluminum glazing beads are designed to be removable from the interior. This allows maintenance teams to extract the broken double-glazed unit and install replacement glass without compromising the main door frame or the thermal break.
