PC20 & PC25 Slim Sliding Doors

MAXIMUM LIGHT – MINIMAL FRAMES

PC20 & PC25 Slim Sliding Doors – Maximum Glass, Minimal Frame

Our PC20 aluminium sliding doors feature an ultra-slim 20mm central interlocking frame combined with a smart design that allows the entire sash to be completely concealed within the building’s wall chamber, delivering a full 100% opening for seamless indoor-outdoor living.

Slim, Modern Design with Outstanding Performance

The thermally broken PC20 sliding system maximises glazing area with minimal visible frame, creating an elegant, contemporary look. The central interlock is just 20mm wide, or 25mm with the XL option designed for taller sashes over 3 metres high.

Innovative GALANDAGE System for Total Opening

The PC20 incorporates a new GALANDAGE sliding system that fully conceals one or two sashes inside the wall cavity, offering either a single or double sash door with 100% opening capability. Choose from mono-, two-, or three-rail configurations depending on your space and style requirements.

Smooth Operation and Durable Construction

Equipped with a stainless steel rail, the PC20 sliding doors ensure smooth, effortless sliding and enhanced durability for long-term reliability.
