About the Twin Top Vents over Full-Width Fixed window

The Twin Top Vents over Full-Width Fixed window is split into two rows by a transom. The top row has two top-hung vents, above a single full-width fixed pane. Two of the three panes open; the other is fixed.

The two top-hung vents, hinged along their top edges, give secure, controllable ventilation. The fixed pane has no sash, so more of it is glass. Sizes run from 800 to 2600mm wide and 730 to 3030mm high, to the millimetre; they're overall sizes including the cill, as our measuring guide explains. The widest it goes is 2600mm: up to 1300mm for each vent.
