About Our UltraSky Roof System

A stronger, thermally efficient ridge means fewer bars are needed, allowing our Ultrasky roof to flood 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.

Our lantern conservatory Ultrasky roof is compatible with our structural goalpost and works with large spans of glass or doors – resulting in uninterrupted views and a stunning design.

Orangery Roof Styles

Choose from the two following options to complete your design:

  • Double hipped with box gutter
  • Georgian
UltraSky Roof System Conservatory Overview

Create an orangery conservatory that performs and looks the way you want it to and which will add market appeal to your home.

Building your ideal orangery extension

Choose our Contemporary Orangery to enjoy a fresh and modern design. Sliding or bi-fold doors combined with full-height glazing will open your space, while the perimeter ceiling will create a ‘room like’ feel. You’ll be able to enjoy better access, improve comfort and a room that feels connected to the outside.

When you choose Ultrasky, you’ll benefit from a high-performing roof system and much more. If you add super-insulated columns, they will deliver thermal efficiency levels five times higher than brick. These will work in tandem with the insulated internal pelmet to create a cosy place and keep you warm.

Choosing the right enhancements

To make the most of your Ultrasky roof, consider introducing bi-fold doors. The invisible structural goalpost within your roof allows concertina-styled doors to be included and eliminates deflection.

Combine super-insulated columns with a decorative cornice, which is available in a 1, 2 or 3 tier format and bespoke colour. Visually and practically, the Ultrasky roof will add long-lasting value to your home.

Why Choose The Ultrasky Roof

A better orangery roof solution

Light and style are perfectly embodied in our Ultrasky roof. The bars extend all the way down to the eaves beam, rather than sitting on a flat roof like a traditional lantern roof.

Superior illumination

The Ultrasky roof uses fewer bars to let in even more light. A decorative cornice is used outside to hide the guttering and create beautiful sightlines.

Incredible comfort

The internal variable insulated pelmet comes with our lantern roof and will enable you to enjoy better lighting and thermal performance.
You can even opt for integrated speakers to enhance your experience. This will be a comfortable space you can live in throughout the year.
