Arcadia Custom makes custom window and door solutions from a range of materials, styles, and finishes. Arcadia Custom windows are precision engineered for high-performance in the harshest environments. Wood windows are often associated with a high level of upkeep. Arcadia Custom's Accoya® wood windows are designed to be low maintenance and weather-resistant, even in challenging conditions.
Accoya® Modified Timber
A sustainable modified timber, Accoya® is an ideal option for external wood window frames, doors, and window shutters. It offers better thermal insulation properties than common hardwood and softwood species while being more durable and having better structural integrity than the best tropical hardwoods. Ideal for coating, Accoya® wood can last twice as long as other wood materials, saving time, money and upkeep.
Created from sustainably-sourced wood, Accoya® undergoes a proprietary, non-toxic acetylation process that permanently modifies the wood to the core. Once the process is complete, the Accoya® wood is harder, more durable, and more resistant bacteria, to temperature change, and rot. Its capacity to absorb water is reduced by up to 80% making it far more dimensionally stable. Furthermore, the compositional alteration that occurs means that fungi do not recognize Accoya as wood and will not attack it. The process also makes Accoya indigestible to insects, eliminating the risk of infestation. It is durable, dimensionally stable, and non-toxic. Accoya® is based on the Acetylation of plantation grown softwood, the gold standard in the academic field of wood science for over 80 years.
Sustainability & LEED
Accoya® can help to earn LEED v4 credits for energy and atmosphere, materials and resources, and indoor environmental quality. In some instances, Accoya® can help reach double the criteria limit.
