KEY ADVANTAGES

01

Engineered for Modern Outdoor Living & AS2047 Certified Performance

Crafted specifically for the modern outdoor living lifestyle, this bi-fold patio door bridges interior comfort with exterior openness through its wide-span folding panels. The thermal break 6063-T5 aluminum frame (2.0 mm wall thickness) is engineered for superior structural integrity — protecting residences, garden-access spaces, and commercial outdoor areas from wind pressure and weather exposure. Certified to AS2047 Australian standards, NFRC, and CE, this door meets the most stringent international building codes. Whether installed on an Australian coastal home, a European villa garden entrance, or an American backyard patio, this door’s robust construction safeguards occupants while delivering the panoramic open-air experience essential to modern outdoor living culture.
02

CMECH Hardware: American Quality, Smooth Folding Operation

CMECH American brand hardware is the standard fitting for this bi-fold door — a trusted hardware brand recognized for consistent operating performance and long-term reliability in folding door applications. All CMECH hardware components feature corrosion-resistant construction rated for hundreds of thousands of folding cycles, making them especially suited to outdoor environments exposed to humidity, salt air, and temperature fluctuations. The precision-engineered folding mechanism ensures effortless panel-by-panel operation, allowing homeowners to fully open their living space to the outdoors in seconds.
03

Thermal Insulation & Soundproof Performance

The thermal break aluminum profile design creates an effective barrier against heat transfer, significantly reducing energy consumption for heating and cooling. Combined with double-tempered insulated glass filled with argon gas (5mm+20A+5mm), this bi-fold door delivers exceptional thermal insulation performance — keeping interiors cool in summer and warm in winter. The multi-chamber profile structure and sealed glass unit also provide outstanding soundproof capabilities, reducing external noise penetration by up to 35 dB, creating a peaceful indoor environment even in busy urban or roadside locations.
04

Screen Netting & Versatile Ventilation

Available in both Nylon and Fiberglass screen netting configurations, this bi-fold door accommodates the full spectrum of outdoor living needs. The fiberglass screen provides superior durability and resistance to UV degradation and deformation — ideal for long-term outdoor installations. Nylon screens offer a flexible, cost-effective ventilation solution for residential balconies and patio enclosures. When the bi-fold panels are fully opened, the screen netting maintains insect protection while allowing maximum airflow — perfect for tropical and subtropical climates where natural ventilation is essential to comfortable outdoor living.
05

Powder Coated & PVDF Surface with Modern Aesthetic

The standard powder coating or PVDF surface treatment provides exceptional long-term UV resistance, anti-corrosion protection, and color consistency — delivering lasting beauty that holds up through intense UV exposure, coastal salt air, and high-humidity outdoor conditions. The modern design aesthetic of the 80 Series profile, with its clean sightlines and slim frame geometry, complements contemporary residential architecture, open-plan garden living extensions, and minimalist facade systems. Available colors include White, Black, Grey, Bronze, Champagne, Dark Brown, and fully customizable RAL or Pantone specifications.
