Accoya Inspiration

Ingenuity to create something unforgettable

Accoya wood is exceptionally stable and resistant to rotting, making it the perfect material for any outdoor application, not just windows, doors, cladding and decking. Now you can use wood in ways you’d never imagined.

Whether you require practical and functional updates for your home or elaborate and show stopping structural builds or bridges, Accoya wood is the perfect material.

For structural creations where once only steel and concrete would be the option – Accoya brings structural stability and design flexibility to the table, combined with the aesthetic that only real wood can truly deliver.

And to enhance your home, where wood is seen as short-lived and impractical, Accoya turns this outlook on its head. You can bring the outdoors in with a timber garden room or create an entirely new space with freestanding buildings such as summer houses and garden offices. Or even update your outdoor surroundings with stylish Accoya furniture, durable fence posts and gates. Using Accoya wood, the possibilities are endless.

Industry leading warranty

With our unmatched 50-year warranty for above ground applications and 25 years below ground or in fresh water, feel confident that your Accoya creation will stand the test of time.

Multiple finishes

Smooth, brushed, charred – on Accoya products, whatever your design demands, you can choose from a multitude of bespoke finishes.

Low maintenance

Accoya wood shrinks and swells much less than other wood species. Limited distortion means minimal maintenance.

Natural wood

Accoya is a world-leading natural solution against huge global environmental concerns – including climate change, ecosystem destruction and finite renewable resources.

Inspirational products

Accoya wood is very easy to work with and can be manufactured into many different products for the home and in commercial settings.

Tested to the limit

60 year service life

After running tests and reviewing external and independent data, the BRE concluded that Accoya wood, provided best design practice is followed, has a service life expectancy of 60 years when used in exterior applications such as timber doors and wooden door frames.

Part Q compliancy

To enable building regulation Part Q compliancy, Accsys in collaboration with UKAS approved test houses of timber window and wooden door manufacturers, ancillary suppliers to our industry and the BWF Federation has developed a security global assessment. This document allows for the successful security testing of Accoya windows and doors to be cascaded down to window and door manufacturers, thus limiting the need for further testing.

Thermal Performance

Accoya thermal conductivity has been assessed by IFT Rossenheim, Germany in accordance with EN 12664 and then developed into the required declared value format, under the most rigorous European assessment methods by the EN ISO 10456: 2008 procedure for determination of declared and design thermal values.

In comparison to other standard wood types for joinery, Accoya thermal conductivity is:
› Superior to softwood by 8%
› Superior to hardwood by 30%

Coatings & Finishes

A fully factory coating can be applied on all Accoya products. A variety of colours and finishes have been tested by leading coating manufacturers with outstanding results. Some examples can be seen below but the possibilities are endless.

Accoya flooring for Omnisport Apeldoorn velodrome

Case Study

Accoya flooring for Omnisport Apeldoorn velodrome

Velodrome specialists SDA from Stompetoren, North Holland used Accoya to replace larch for the cycling track in the Omnisport Apeldoorn multi-sport indoor arena. SDA’s portfolio also includes impressive velodromes such as: Athens, Mexico City and Majorca.

Accoya was chosen because of its stability, low maintenance and less splintering than other woods.

Award winning Moses bridge

Case Study

Award winning Moses bridge

Fort de Roovere, the largest fort on the line required the addition of an access bridge. The fort is surrounded by a moat and was originally built without a bridge so it was a challenge to create one that would be discreet.

RO&AD architects’ solution was to build a ‘sunken’ bridge that follows the line of the fort slope and sits almost flush with the soil and the level of the water, making it practically invisible as you approach the fort. The bridge is built from Accoya wood sheet piling on either side, with a hardwood deck/stairs in between.

Accoya product FAQs

  • Virtually all wood preserving treatments today work by impregnating toxic chemicals (such as arsenic, oils, ammonia or metal compounds) into the cell walls of the wood. This works to fill the voids within the wood but this doesn’t change the underlying chemistry. The toxicity of such products also have negative environmental implications during the serviceable life of the wood as well as during its disposal.

    As an alternative, Accoya alters the wood’s structure to the core, creating an inhospitable environment and helping to control unwanted organisms, such as bacteria, viruses and fungi. The main alternative non-toxic preservative treatment to Accoya’s acetylation is “thermal modification”, a process which works by breaking down the edible components of the wood. However, the process both discolours and weakens the wood, rendering it unsuitable for many uses.

    The Accoya production process does not weaken the original wood – in fact, its hardness is slightly improved and its bending strength uncompromised. Indeed, no modification process exists which offers the performance benefits and retained physical properties of Accoya.

  • Wood is an amazing material with many possibilities and practical applications. One of the major drawbacks of wood though, especially softwood, is how it interacts with water. Moisture causes the wood to swell and shrink, and accelerates damage and decay.

    So, what is acetylation?

    Wood naturally contains some acetyls, but also a lot of ‘free hydroxyls’ – these are what water binds to, causing all those problems. In our reactors, our process uses acetic anhydride – essentially very strong vinegar – to boost the acetyl content of the wood, replacing those hydroxyls…meaning water is no longer an issue.

    This means we’re not adding anything to the wood that wasn’t already there – no toxic elements that could later leach out - we are really enhancing the natural qualities of the wood.

    Even the by-product of our process is part of the circular economy: acetic acid is valued in its own right, used in other products, processes or even turned back into acetic anhydride – offering a potentially ‘closed loop’ cycle for our chemistry.

    We constantly refine and improve our processes to improve quality and efficiency, and research the effects with different wood species.

  • Accoya wood is made from radiata pine trees. These are sourced and taken to our production facilities in the Netherlands where they undergo a modification process, more specifically known as Acetylation. This process turns the radiata pine wood into the worlds most stable wood, Accoya.

    More information about the Acetylation process can be found here.

  • Accoya wood begins life in sustainably managed forests in New Zealand as a tree species called Radiata Pine. These forests are all FSC approved. The Radiata Pine is fast-growing and is shipped from here to the Netherlands for the modification process.

    We then ship across the world to our approved distribution partners. For more information on our route to market, click here. Despite the journey Accoya wood may go on before reaching you, it is still a sustainable choice and this can be shown here.
