Accoya is a world’s leading high performance wood. Created from sustainably-sourced wood, Accoya undegoes a proprietary acetylation process that permanently modifies the wood to the core. The result: an environmentally friendly solid wood with durability, dimensional stabilIity and beauty that matches or exceeds even the best tropic hardwood.
But the acetylation process does not turn the Accoya fire-proof – it burns in the same way or even better than ordinary wood. Being a ‘special wood’ also requires a special fire retardant that must be tested and certified on Accoya. Fire retardants meant for ordinary wood do not work on Accoya, and their certificates do not apply for Accoya.
Being a relatively new product Accoya is already well introduced in the building industry in more than 50 countries of the world. It is perfect for cladding, siding and facades where wood’s natural beauty is desired and sustainability and high performance are of the utmost importance. In decking, where it is important that boards do not warp, bow, twist, split, Accoya is up to the challenge.
Ultra-A is suited for application by spray, roller, brush or immersion, as well as in a coating-machine and autoclave. Treating Accoya with Ultra-A leaves the appearance of Accoya unchanged and brings out the texture and natural beauty of the wood.
