Aluminium is ideal for bay or bow windows because of its inherent strength, but where multiple panes are used as facets around a curve, every coupling which connects the frames interrupts the view. Because Stellar has the slimmest sections on the market, this problem is minimised. There is more glass and more light can enter your home.

Protection against the weather is guaranteed. Stellar has built-in thermal-break technology to insulate your home. It has seals which prevent draughts and water ingress, and it can accommodate either double or triple-glazed units.

Bay and bow windows, like every other part of the Stellar range, can be customised to your needs. The styling can be kept plain and simple, but it’s also possible to incorporate decorative features like glazing bars and stained glass.
