Our export-grade doors are not merely adapted but are fundamentally engineered from the material level up for seamless, durable integration into Australian residential and commercial architecture, with full compliance to the AS/NZS 2047 suite of standards for windows and external glazed doors.

Core Material Engineering for Durability

The structural integrity and longevity of a garden door are determined by its composite makeup and core stability.

  • Advanced Wood-Plastic Composite (WPC) Profiles: We utilize high-density WPC (≥ 1.3 g/cm³) with a meticulously controlled wood fiber-to-polymer ratio. This optimizes dimensional stability, yielding a linear thermal expansion coefficient of < 0.06 mm/m°C, critical for preventing warping or binding in Australia’s temperature ranges. The formulation includes UV-inhibiting stabilizers and impact modifiers, achieving a Shore D hardness of >75 for superior resistance to physical abrasion and hail.
  • Engineered Wood Core (LVL) in Hybrid Systems: For doors requiring the aesthetic of timber with engineered performance, we employ Laminated Veneer Lumber (LVL) cores. LVL provides a stability factor far superior to solid timber, with moisture content controlled to 8±2% at fabrication and swelling rates below 1.5% after 24-hour water immersion (ASTM D1037), ensuring consistent operation in humid climates.
  • High-Performance Glazing & Seals: Glazing units are specified with warm-edge spacers and argon fill to achieve a centre-pane U-factor as low as 1.1 W/(m²·K). Seals are made from EPDM (Ethylene Propylene Diene Monomer), selected for its ozone and UV resistance, with a continuous compression set of <25% (ASTM D395) to maintain a consistent weather seal over the product’s lifecycle.

Garden doors export to Australia with AS/NZS certification

  1. Structural Opening Preparation: The rough opening must be square, level, and plumb within a 3mm tolerance over the door’s height and width. A continuous, load-bearing structural support is required beneath threshold installations.
  2. Weatherproofing & Flashing: Integrate the door assembly with the building’s weather-resistant barrier (WRB). Apply a fully adhered, high-performance flexible flashing system at the head and jambs, directing water outward and away from the structural opening. Seal all frame joints with a structural silicone or compatible polyurethane sealant.
  3. Anchoring & Fixing: Use only corrosion-resistant, manufacturer-supplied fixings. Anchor points must be within 150mm of corners and at intervals not exceeding 400mm along the frame. Do not overtighten, as this will distort the frame profile.
  4. Insulation & Sealing: After installation, fill the cavity between the door frame and rough opening with a non-expanding, closed-cell foam backer rod, followed by a low-modulus silicone sealant on the exterior. On the interior, use an expanding foam suitable for windows and doors, applied in multiple shallow lifts to prevent frame distortion.
  5. Hardware & Adjustment: All multi-point locks and hinges must be adjusted to ensure uniform compression of perimeter seals. The door leaf should move smoothly without binding. Final weather seal compression should be visually even around the entire perimeter.
  6. Drainage: Ensure all factory-provided drainage weeps in the bottom rail and threshold are clear and unobstructed. The sill must be installed with a minimum 5° outward slope for positive water drainage.
