The Opus window is the perfect harmony of cutting edge aluminium and rich, natural timber. Durable and maintenance free aluminium externally offers unrivalled longevity and sharp clean aesthetics, whilst internally hardwood offer richness, beauty and a natural finish.

With hundreds of RAL colours to choose from for the aluminium exterior from a soft traditional Chartwell Green to a sophisticated and contemporary Anthracite Grey, Opus windows will uniquely enhance your home. We also have a selection of three hardwood finishes available for the window internally, to ensure the correct tone is set for your home for years to come.

The slimline external profile of the Opus window ensures maximum glass size, which allows light to flood into your home, making them ideal for both replacement windows to your home, as well as for new Orangery installations.

As well as being beautiful to look at, Opus windows ensure security for your home, with the use of the latest multi-point locking mechanisms, fixed through internal timber face to the aluminium structure.

In addition, you can be assured that the timbers used in Opus windows are carefully sourced and carry an active environmental accreditation and are fully traceable.

What our customers' say...

"We have had all our windows and doors, fascias and soffits replaced together with removing a door which also involved bricking up the space. They have matched the brick work brilliantly. The care and attention to detail in the work together with their willingness to meet specific individual requirements has been magnificent. A conservatory is next on our wish list and when we are ready Croston Conservatories will be at the top of our list of companies we will consider."
