modified wood by Accsys Technologies PERFORMANCE TESTING SUMMARY TRIED, TESTED AND PROVEN Accoya® is a product of Accsys Technologies

Accoya® wood is the result of over 80 years research and development. Combining the proven modification technique of acetylation with cuttingedge proprietary technology, this high performance wood is created for demanding outdoor applications; from windows to doors, decking to cladding, bridges to boats. 03 Life cycle assessments – Camco / TU Delft Accoya® wood outperforms concrete, steel and aluminium 11 16-year canal lining test Accoya® wood exhibits no rot or decay after 16 years water and soil exposure 04 Carbon footprint – Camco / TU Delft Accoya® wood’s carbon footprint is less than...

LCA AND CARBON FOOTPRINT – CAMCO / TU DELFT The Carbon Footprint Reports from Camco UK and the Life Cycle Assessments from TU Delft, conducted using ISO 14040 compliant processes, both show that Accoya® wood outperforms competing building materials and is less harmful to the environment. ENERGY UNITS REQUIRED TO MANUFACTURE 1 TON OF BUILDING MATERIAL Independent research and testing has proven Accoya® wood’s superior environmental performance. ACCOYA® WOOD: • ses less energy than cement, glass, steel and aluminium U when utilised as a building material • ts manufacture emits less greenhouse...

LCA AND CARBON FOOTPRINT – CAMCO / TU DELFT The Carbon Footprint Reports from Camco UK and the Life Cycle Assessments from TU Delft, conducted using ISO 14040 compliant processes, both show that Accoya® wood outperforms competing building materials and is less harmful to the environment. A carbon footprint assessment was carried out on Accoya® wood using standard emission factors as referenced in the Camco study in line with the World Business Council for Sustainable Development and World Resources Institute’s (WBCSD/WRI) Greenhouse Gas (GHG) Reporting Protocol best practice guidelines...

SUPERIOR WHOLE LIFE COST FOR WINDOWS LIFE CYCLE COST FOR WINDOW FRAMES IN A TYPICAL DUTCH HOME B A study with a Dutch window producer/ maintenance company shows that Accoya® is initially more expensive but has a lower total cost than PVC, aluminium, pine and hardwood windows over a reasonable ownership period. ACCOYA® WOOD: • Ensures lower maintenance costs • Ensures longer time between maintenance • as extended durability and won’t need replacing H for 50+ years Accoya® wood Spruce - Hardwood Cost effectiveness (£ per 60+ years) Life maintenance cost Superior Whole Life Cost For Windows 5

DURABILITY COMPARISON – SCION The harsh test site runs exposed timbers in accelerated decay chambers and in exterior ground contact tests at the Whakarewarewa site. The tests have run for six years and show Accoya® performing better than teak, merbau, cypress, cedar and H3.2 (above ground, uncoated horizontal) and H4 (in ground contact) preservative (CCA) treated timbers, proving that Accoya® has the highest possible durability classification. DECAY RATES OF FUNGUS CELLAR STACKLETS 10 Accoya® wood Accoya® wood Radiata Pine = No decay or insect damage = iscolouration or trace of decay, not...

13-YEAR WINDOW L-JOINT TEST – BRE The BRE (Building Research Establishment) is an independent institute based in Watford, UK. In durability field testing to European Norm (EN) 330:1993 – which parallels America Wood-Preservers’ Association (AWPA) E9 – simple mortice and tenon joints (L-joints) are assembled, coated and placed outside, with the coating over the joint deliberately broken to allow typical water ingress. This test represents a worst case scenario for joinery products and requires the coated wood to be exposed to normal environmental factors. In February 1998, L-joints were...

60-YEAR SERVICE LIFE - BRE 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 windows, doors, cladding and balconies. The BRE stated that Accoya® wood shows excellent durability and stability properties. “We consider that joinery, cladding and balconies prepared from Accoya® will show significantly improved coating performance properties. If the products are designed and built to the principles of best practice (to...

FORMOSAN TERMITE DURABILITY TEST - LSU Coptotermes formosanus, known as Formosan termites, are considered one of the world’s most aggressive termite. Louisiana State University (LSU) conducted a 99 day formosan termite ‘choice’ test, using untreated radiata pine and Accoya® wood (2” x 4” lumber). LSU FORMOSAN TERMITE TEST RESULTS New Zealand Radiata (Leached) New Zealand Radiata (Un-Leached) % Weight Loss All four sides of the untreated radiata pine were attacked and left structurally compromised. In stark contrast, Accoya® wood only exhibited slight grazing. Chilean Radiata (Leached) The...

FIELD TEST – KAGOSHIMA TEST SITE, JAPAN The extreme two year field test conducted was primarily against two different types of termites in two locations of the field site located in Kagoshima, Japan. Coptotermes formosanus is present in a dry area and Reticulitermes speratus is active in a wet area of the site. Collectively the sites also have an assortment of rot fungi present including white and brown rots. Non Accoya® wood, wet test site Accoya® wood, wet test site Non Accoya® wood, dry test site Accoya® wood, dry test site Unacetylated stakes (both of sugi and radiata) performed poorly....

16-YEAR CANAL LINING TEST Accoya® wood’s high performance was proved with a 16year project test from Waterschap Zuiderzeeland, near the junctions of the N301 and N305 Nijkerk – Zeewolde. In April 1995, acetylated and control wood was used to line a canal. After 16 years of exposure to fresh water, the acetylated wood showed no sign of rot, decay or fungal damage – highlighting its class 1 durability status. BS8417 indicates a 30 year service for durability class 1 in this fresh water scenario and Accoya® wood canal linings are showing real life positive results. These canal bank conditions...
