Why choose Single Door SD-3?

Warp-Resistant Laminated Spruce Frame

All door components exceeding 160cm in length are crafted from laminated spruce, engineered to resist warping under changing moisture and temperature conditions. This ensures the door maintains a consistent fit and appearance over years of outdoor use while retaining the visual character of solid timber.

Double-Glazed ESG Unit for Thermal Performance

The SD-3 is fitted with a 4+6+4 ESG double-glazed unit, sealed with silicone sealant for airtight integration. This glazing configuration improves thermal performance and reduces condensation.

Full Weatherproofing Package

Rubber draught excluders fitted to the door frame effectively block wind and water ingress, while a spruce casing with rubber sealants reinforces the perimeter seal. An aluminium threshold strip protects the base from wear and moisture at the critical floor junction.

Site-Adjustable Hinges with Decorative Finish

The door hinges allow full three-dimensional adjustment using a standard allen key, enabling precise alignment after on-site assembly. Decorative black covers are supplied with each hinge, providing a clean, finished appearance.
