Fixed window with top light in Schüco LivIng Slide

LivIng Slide is the lift-and-slide patio door from Schüco's uPVC LivIng family: an 82 mm sash with a steel core, Uf 1.3 W/m²K and glass up to 54 mm thick. The sash is 82 mm deep and built up from four chambers, with a steel core inside, and achieves a Uf of 1.3 W/m²K; combined with insulating glass, a Uw down to 0.80 W/m²K is achievable. The outer frame itself is 194 mm deep, the sightline starts at 180 mm, and a single sash can be up to 3,200 mm wide and 2,600 mm high. The threshold is thermally broken and has fourteen chambers; it can be fitted flush with the floor, so you step from inside to outside without a step. Three levels of seals all round keep draughts and water out and bring the sound insulation to 45 dB. The glass can be up to 54 mm thick, so triple glazing fits 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.
