These window styles are often seen on period properties with stone cills. We offer a wide range of options that can enhance any property.
D Frames are by their nature a D shape and have a subtle curve at the head of the window. Like many of our specialist windows, they are fully welded and there’s no sight of any mechanical join, just a complete smooth finish.
Choose a D Frame from Universal Arches and you will benefit from a product that can be manufactured within millimetres, which makes onsite installation easier and far neater.
