uPVC Windows
uPVC Fixed / Picture Window
Non-opening glazing for uninterrupted views and the highest thermal performance.
With no opening sash there is no air leakage path at all, so a fixed window is the best-performing option for heat and sound. It also carries the slimmest sight lines, which is why it is used for stairwell glazing, gable ends and picture views.
Usually specified alongside an operable window in the same combination frame.
Key highlights
- Zero air leakage
- Slimmest sight lines
- Best thermal and acoustic figures
- Large glass spans possible
- Pairs with any operable system

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.
