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 wooden doors and frames.

Part Q compliancy

To enable building regulation Part Q compliancy, Accsys in collaboration with UKAS approved test houses of wooden window and 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%

As part of a recent restoration program, 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 wood’s durability and guaranteed performance in-ground and in freshwater made this possible.
