Ultrasky Aluminium Orangery

Choose the Ultrasky roof with aluminium doors if you want a home extension system that combines modern styling with natural light to create a beautiful warm and glazed extension. Strength is the secret behind Ultrasky's success.

A stronger, thermally efficient ridge means fewer bars are needed drawing more light into the room. The Ultrasky roof extends to the eaves beam, rather than a flat roof, and uses the internal pelmet and external cornice to create a beautiful orangery roof style.

They are wonderfully light and airy spaces due to the glazed roofs as well as being cosy and inviting throughout the year. And don’t forget the outdoors – an orangery can help you to get the most out of your garden too.

Consisting of anywhere between 3 and 7 panels, bifold doors spoil homes with light thanks to an emphasis on crystal clear glazing that blurs together inside and outside living spaces whether open or closed.
