GR145 INOWA Sliding Door
The minimal-sightline sliding wall: a 145 mm system engineered for the narrowest possible meeting stile, so a run of glass reads almost frameless when closed.
Engineered for the slimmest interlock in the range, so the eye meets glass rather than frame. The deep fiberglass section still carries triple glazing across a wide span and seals down for Passivhaus-grade air and thermal performance.

What is a sliding window or door?
A sliding window or door runs one or more panels horizontally on a track, one gliding past the next. Because the panels stay in the plane of the wall, a slider opens a wide view and passage without sweeping into the room, which is ideal where floor space is tight. Configurations run from two panels up to multi-panel and pocketing runs that slide away into the wall.
