The Extension Project of Choice

Orangery extensions are an increasingly common project that we see across our desks here at ETS. With little impact on the existing property and often without the need for time-consuming wrangling with planning departments, this method of extending your home is both quick and easy.

Large roof windows or lanterns and glazed walls allow you to bring the outside in and create a light and airy space in your home. This addition to your kitchen or living room can truly change the feel of your home and give you the space you crave while adding significant value to your property.

Lose those Steel Beams

Often orangery roofs are specified with loose timber and steel beams for the roof construction, as a direct consequence of this the roof can often be unnecessarily complicated and expensive. Lantern weights are commonly more than 500kg and must have the appropriate support in place.

Our metal web joists provide the perfect solution to these requirements. Offering superb levels strength, our metal web joists can remove the need for these steel support beams, simplifying your supply chain and reducing costs.

The properties of our metal web joists, in comparison to solid timber or alternative engineered timber beams, combined with the lightweight nature of the metal web joist system, resulting in a solution that’s easy to handle and install.

In conjunction with the latest Pamir design software by Mitek, our metal web joists allow the designer to manipulate the joist end details to suit intricate design details that are commonplace in orangery design. Alternative products cannot offer this versatility.

These intricate details include, but are not limited to:

  • Parapet wall details
  • Hanging from ledgers fixed to the existing structure
  • Fixing into steels to create openings into the new structure
  • Soffit/gutter detail requirements

Why use ETS for Orangeries?

We’ve been working with many orangery roof installers for many years. During this time, we have built up extensive know-how on the best design and detailing methods. Although often small projects they are usually the most design intensive due to a variety of roof loading considerations such as snowdrifts, wind uplift lantern weights and many more.

Orangeries are relatively quick to erect, in these quick turn around projects, our five working day lead-time promise comes into its own, offering a site measure if required, design, manufacture and supply of the metal web joists to suit your build programme.
