A high-performance sliding door with an accessible ultra-flat sill for seamless internal-to-external transitions.
ProGlide UltraFlat is intended for large openings where access and weather resistance must be considered together. The low-profile sill can support a continuous accessible path when detailed and installed as part of the complete building interface.
Performance Windows custom fabricates each unit. Dimensions, finish, glass, screens, hardware and installation details are confirmed through the quotation and specification process.
An ultra-flat sill needs early coordination with interior floors, exterior surfaces and drainage. Send a section through the doorway, including waterproofing and paving levels where available. Discuss any required accessible path with the building designer; a low-profile sill alone does not confirm the compliance of the complete route.
The opening’s exposure, size and glass weight influence the suitable configuration. Confirm panel travel, clear access, screening and the installation interface before surrounding construction is finished. Ask the project team to review the proposed threshold detail alongside the system’s current performance documentation.
