CLARELIO systems on Cortizo platforms — architecture film, 2022.
CorVision Plus is the minimal-frame sliding system — concealed central interlock, flush recessed handle, and a zero-threshold floor track that runs level with the finished floor. No step, no visible hardware, no compromise on security.
Where the brief calls for the purest possible sightline and a seamless indoor-outdoor transition, CorVision Plus delivers wall-to-wall glass with a near-invisible meeting stile.

CLARELIO systems are engineered on Cortizo aluminium platforms — the same extrusion technology specified across Europe's most demanding envelopes.
We don't reinvent the profile. We make the engineering behind it transparent — so architects spec with confidence and builders install to a written tolerance.
Manufactured in Europe on Cortizo® platforms to continental tolerances, CE-marked to EN 14351-1, warm-edge as standard.
Architect, builder, developer or glazing contractor — we'll send the full technical documentation and work with you directly on your project.
