uPVC bay windows, semi-hexagonal and custom
A bay window projects out from the wall in three angled frames, so light comes in from three sides and you gain a deep sill or window seat. We design, make and fit bay windows to the exact angles of your structure.
Types we make
Every unit is made to order at your size. Open any of them in the planner to see it drawn at your dimensions.
How our semi-hexagonal bay works
Our usual layout has a sliding pair in the centre and top-hung vents over fixed panes on the two angled sides. The vents open outward from the bottom, so you get fresh air even in light rain, while the centre slides open for a full view. Corner posts join the three frames at the angle of your bay.
Made to your structure
Bays are never standard. We measure the width of each face and the angle between them on site and draw the window before anything is cut. See how it opens in the 3D view on our homepage.

Questions we're asked
Can a bay window open for ventilation?
Yes. In our semi-hexagonal bays the centre slides open and the side panels have top-hung vents, so the bay ventilates from three directions.
Do you make bay windows in other shapes?
Yes. We make semi-hexagonal (three faces at 45°), box bays and other angles to suit the structure. We measure each face on site and send a drawing for approval.
How quickly can you make and fit them?
We come to measure as soon as you place the order. One or two windows or doors are usually made in our Vadaperumbakkam factory and fitted within 1–2 days. Larger orders take a few days more depending on the number of openings, and we give you a fitting date when we measure.
Which uPVC profile do you use?
We build with Three Diamond uPVC profiles, made in Chennai. They are lead-free (calcium-zinc stabilised), UV-stabilised with titanium dioxide for strong sun and coastal air, and tested at CIPET, the Government of India's plastics testing institute. The profile warranty is Three Diamond's, handed over in writing with your invoice.
