The Coplanar Flush Sliding Door System is a top-hung sliding door that sits perfectly level with the wall, creating a seamless, hidden look. It solves the problem of bulky, visible sliding doors by allowing the door to blend into the surrounding surface, making it ideal for hidden rooms, integrated wall panelling, and modern, minimalist designs.

For architects and builders striving to create seamless, modern interiors, the internal Coplanar FlushSlide Door System is a game-changer. This innovative system offers a sleek, minimalist aesthetic while delivering superior functionality, making it the ideal choice for high-end residential and commercial projects. Whether you’re designing concealed pantries, hidden ensuites, or integrated wall-panel doors, the Coplanar system brings sophistication and practicality into perfect harmony.

Seamless Aesthetics for a Modern Look

The demand for clean, uninterrupted interior lines has never been greater. With its flush integration, the Coplanar system allows doors to sit perfectly level with the surrounding walls or joinery. Unlike traditional sliding doors that remain visible or protrude when closed, this system disappears into the architecture, creating a hidden yet functional transition between spaces.

For designers working on high-end homes, luxury apartments, or commercial fit-outs, this level of refinement is essential. The ability to blend doors with wall paneling or finishes—whether timber, laminate, or painted surfaces—ensures cohesion and continuity throughout an interior space.

Practical Benefits for Builders

For builders and contractors, the Coplanar Flush Sliding Door System simplifies installation while enhancing the overall build quality.

• Straightforward Installation: The system includes comprehensive installation, guiding teams through the process.

• Factory-Packaged Setbox: Each system is shipped as a complete set, ensuring all necessary components arrive together for a hassle-free install.

• Versatile Applications: Suitable for walk-in pantries, ensuite doors, hidden toilets, and more, making it an adaptable solution across various projects.
