Non-standard windows

The calculator gives a correct price for ordinary shapes. A complex shape brings in factors it ignores: the number of cuts, specially cut glass, adapted hardware. An automatic price here would be wrong rather than approximate — so we prefer a written quote once we have seen the exact shape.

Yes, round and oval shapes are made. They are usually fixed, because a curved opening frame is expensive and rarely justified. At the survey we discuss whether a fully round shape makes sense or whether rounded corners, which cost less, will do.

There is a limit beyond which the PVC profile no longer holds without being split, and the glass becomes too heavy to handle safely. When we exceed it, we split into sections — not for convenience, but so the window survives for years. If a single very large, rigid plane is needed, sometimes the right answer is an aluminium profile, and we will say so.

Longer than a typical window, because the profile is cut differently and the glass is often ordered specially to the shape. We give the date once the shape is confirmed. We do not start producing a complex shape until there is an agreed drawing or template — a wrongly made shape cannot be corrected.

Lamination over standard white adds to the price, and colours outside the usual range are ordered with a longer lead time. Anthracite and wood imitations are in regular demand and have a predictable price. A rare RAL colour can be done, but it is worth knowing in advance that it cannot be returned, being made specially.

The same warranty structured over profile, hardware and installation, written into the contract, as any PVC window. The shape being special does not change the warranty; the exact terms are on the warranty page.
