Product Details
The ultra slim aluminium bifold doors achieve their slim profile through precision-engineered 6063-T5 aluminum profiles and thermal break construction. Unlike standard bifold doors, the visible frame is minimized to maximize natural light and sightlines, making them ideal for spacious patios, restaurant openings, and high-end commercial interiors. The system integrates EPDM sealing strips and multi-point locking to maintain air and water performance even at slim dimensions.
These aluminium glass folding doors support panel configurations from 2 to 10 leaves, with the 80 Series reaching an opening width of around 60 feet. The narrow frame aluminium doors can be configured for inward or outward folding, and the thermal break reduces heat transfer, supporting energy-efficient building designs. This makes them a versatile choice for projects requiring a clean, modern aesthetic and reliable performance.
Product Features
Ultra-slim sightlines: The reduced frame profile enhances glass area, creating uninterrupted views. This slim frame bifold door design suits modern architectural tastes, allowing more natural light into living and working spaces.
Thermal break efficiency: Polyamide thermal breaks within the aluminium structure cut heat transfer, helping meet energy codes. Narrow frame aluminium doors with this feature can contribute to lower heating and cooling costs.
Wide opening flexibility: Panels fold and stack compactly, clearing wide openings. This minimalist bifold door system can span up to 60 feet, connecting interiors with gardens, terraces, or commercial fronts.
All-weather sealing: EPDM gaskets and integrated bent duckbill strips protect against air and water infiltration. These aluminium glass folding doors maintain comfort and durability in exposed installations.
Robust hardware integration: Concealed hinges, multi-point locks, and optional Kerssenberg or CMECH handles deliver smooth operation and security. The hardware suits the slim profile without bulk.
Modern patio bifold doors: With customizable glass choices like Low-E, tinted, and frosted, these doors adapt to privacy and solar control needs. The finish options—powder coat, anodized wood, PVDF—ensure a lasting appearance.
Customizable Styles
Glass options: double or triple tempered, with argon, Low-E, tinted, reflective, laminated, or frosted to meet energy, acoustic, and privacy requirements.
Frame color and finish: choose powder coating, anodized wooden grain, or PVDF coating in custom RAL colors, providing design flexibility for seamless aesthetic integration.
Panel sizing: widths from 500 up to 850mm and heights up to 3800mm (93 Series) allow tailoring opening dimensions; other series offer different ranges. Confirm with supplier.
Track configuration: low track for flush thresholds or high track for drainage needs; suitable for both interior and exterior applications.
Folding direction: inward or outward folding to suit space layout and weather exposure; can be specified per project.
Hardware Accessories
Kerssenberg handles: ergonomic and corrosion-resistant, designed for frequent use in aluminium glass folding doors, offering a sleek touch point that matches the slim profile.
Hidden hinges: allow clean, unobstructed frames on narrow frame aluminium doors, supporting smooth folding without protruding hardware.
Multi-point locks: engage at multiple points for enhanced security, integrated discreetly into the frame of slim frame bifold doors.
CMECH hardware systems: coordinated handle, hinge, and lock point sets ensure consistent quality and compatibility across project-scale installations.
EPDM sealing strips: durable, flexible weather seals tailored to ultra slim aluminium bifold doors, resisting UV and temperature extremes to maintain airtightness.
