The Tricoya Westminster is supplied with leaded decorative double glazing and would be, once finished, a real finishing touch to any period property. The technology behind Tricoya wood is based on acetylation, a process that has been developed by specialists over decades of research and testing. Acetylation changes elements within the wood, reducing the ability to absorb water and adding stability and durability. The acetyl, which provides these qualities, is naturally present within the wood. The technique used to create Tricoya simply increases the proportion of this vital element. A high-tech solution, but one with outstanding performance benefits.
