uPVC Windows
uPVC French Window
Floor-to-ceiling double sashes that open wide onto a balcony, terrace or garden.
French windows are full-height casement pairs with no central mullion, so when both sashes open the entire aperture is clear. They suit balconies, terraces and garden rooms where the boundary between inside and outside should disappear.
We supply them with toughened glass as standard and an optional low threshold for level access.

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.
