Technical Performance Data

Critical Installation Guidelines for Compliance

Installation is integral to achieving the certified performance. Non-compliance voids warranty and 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.
