Accoya was selected as the ideal wood for the custom fabricated windows and doors of this orangery, designed and crafted by Midland Conservatories. Increasingly, Midland Conservatories have found that they have been asked to use Accoya more throughout their projects having seen all the benefits Accoya has to offer.

They now use Accoya as standard for a range of components including all of their opaque door sashes. For this orangery project they designed and built the entire project to the customers specification using Accoya.

Designed by architecture firm Alma-nac, the property, which is called the Split House, replaces a 1950’s bungalow and run-down barn in the village of Fairlight. The architects specified Accoya to construct the external windows, window reveals and doors. 38 Accoya fixed and opening windows were installed, as well as 22 glazed door leafs.

Caspar Rodgers from Alma-nac commented: “We chose Accoya because we wanted to build using eco-friendly materials that could withstand the variable weather conditions that are characteristic of England’s southern coast. Accoya is well-respected within the industry as a highly sustainable product that has high levels of durability and stability.”

Window and door specialist, Dempsey Dyer, turned to Accoya wood in 2008 for the doorsets and window sashes of nineteen townhouses constructed by Bellway Homes in Purfleet, Essex, UK.

One of the key reasons for choosing Accoya was that the wood was to be coated with a challenging black finish (dark coatings readily absorb sunlight) and stability was therefore critical. We revisited the project in early 2011 and found that the Accoya wood used was still looking superb with excellent colour retention and no signs of rot or decay.
