Three-Panel Sliding Door | H2100 x W3600

Maximize your opening capacity and transition smoothly to the outdoors with our mid-format 2100H x 3600W Three-Panel Aluminium Sliding Stacker Door. Engineered using heavy-duty structural profiles, two active door panels stack neatly over a third fixed panel when opened. This delivers a significantly wider ventilation and walk-through opening than standard sliding layouts, making it an excellent centerpiece choice for alfresco entries, primary living spaces, and entertainment zones.

Evolving from high-performance systems used in premium high-rise apartment builds, this structural door setup eliminates the lightweight feel of traditional residential fixtures, replacing it with commercial-grade strength and an upscale architectural finish.

• Weather & Pest Armor: Features an internally hidden weather flap mechanism that significantly cuts down air and water infiltration while keeping insects from breaching structural drain holes.

• Extreme Weather Performance: Available with targeted structural interlock configurations engineered to resist high wind loads and harsh cyclonic environments.

• Fully Certified Standards: Thoroughly engineered and tested to satisfy or exceed strict building compliance standards, including AS2047, AS1170, AS1191, and AS3959.

Eco-Conscious Design & Energy Efficiency

Upgrading standard fixtures with high-performance systems is one of the most proactive choices you can make toward long-term sustainability. Studies by the Sustainable Windows Alliance of Australia show that retrofitting standard openings can lift an entire property's thermal rating by 2 to 2.5 stars. Built using 100% recyclable aluminium, this durable stacking system is an environmentally responsible investment.

While alternative framing requires bulky adapters to hold heavy glass layers, our frames natively accept advanced eco-glazing straight out of the box. Seamlessly integrate energy-saving Low-E glass or up to 10.5mm high-performance thermal and acoustic glass panels with no unsightly frame extensions required.

Pro Tip for Smart Building: For absolute peak climate efficiency, pair your performance doors with robust insulation and ensure primary living spaces face north for optimal seasonal shading.
