uPVC Windows
uPVC Bay Window
Three or more panels projecting outward to create a light-filled seating nook.
A bay window projects beyond the wall line, adding usable floor area and pulling light in from three directions. We fabricate square, splayed and polygonal bays with structural corner posts, so the unit carries its own load without a separate steel frame.
Popular in villas and independent floors where a reading corner or window seat is part of the brief.

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.
