uPVC Top Hung Window
Hinged at the top so it can stay open in the rain — the practical ventilator choice.
A top-hung sash pivots outward from the head, which means the open sash acts as its own canopy. Rain runs off rather than in, so bathrooms, kitchens, staircases and utility areas can stay ventilated through the monsoon.
Available with friction stays that hold the sash at any angle without a separate stay bar.
Key highlights
- Can stay open during rain
- Friction stays hold any angle
- Ideal for bathrooms and kitchens
- Compact — no inward swing
- Optional restrictor for safety

Frequently asked questions
uPVC insulates far better and costs less for ordinary residential openings. Thermally broken aluminium is stronger, so it carries larger panels with slimmer frames. We usually specify uPVC for bedrooms, kitchens and bathrooms, and aluminium for very large sliders, stairwell glazing and anything above about 2.4 metres tall.
Not if the profile is UV stabilised and lead-free, which ours are. Yellowing happens with cheap unstabilised profile or recycled material. We supply a written warranty against discolouration.
An acoustic laminated inner pane inside a double-glazed unit, with the two panes at different thicknesses and a wide cavity. Just as important, choose a casement or tilt-and-turn window rather than a slider, because the sash needs to compress onto its gaskets to seal.
Yes. We bend profile on a heated forming table from a site template, so semi-circular, segmental and elliptical heads are all possible, fixed or with an operable lower sash.
