A window that is arched is rounded at the top while remaining square at the bottom. To retain a sense of modernism to your arch windows, opt for the flat arch range which has a lower degree of roundness at the top. For a more classic look, the fixed arches will make quite a statement.

As with all of our windows, the arched window range also comes with satin chrome handles and high quality 90-degree hinges. These windows are super easy to maintain and won’t creak or pop when opened. Feel free to chat to our consultants about the best way to fit these stylish windows into your budget.

Arch shaped windows bring a softness to a room
