Fixed window with top light in Aluplast Multi Slide

The Multi Slide is Aluplast's sliding patio door for when you don't need a lift-and-slide door. The leaf rolls aside without being lifted first, and because nothing swings into the room, it takes up no space inside. The frame is 80 mm deep, the leaf 60 mm, and the system comes with one or two tracks. For a complete door with glass of Ug 1.0, the system data give Uw 1.4 W/m²K. Made smaller, the same system works as a sliding window.

Light uPVC sliding patio door, 80 mm deep: the leaf slides without lifting, on one or two tracks, and works as a sliding window too.

Two fixed panes one above the other, divided by a transom: a narrow, tall window that only lets light through.

This window splits into two fixed panes: a small one at the top and a larger one below. Neither opens — it is the fixed window raised into a taller, narrower shape. That suits a stairwell, a hallway, or a strip of wall next to a door that already lets in enough air, where you're mainly after height and light rather than ventilation.

The standard size is 1,000 × 1,800 mm, with the top pane taking a quarter of the height and the lower pane the rest. If you do want to ventilate in exactly that spot, the fixed window with tilt-in top light — the same two-part window with a bottom-hung sash instead of the fixed top light — is the form that provides for it, without the look changing.
