This process is how we make AuraLast Wood. Unlike dip-treated wood, which is common in the industry, JELD-WEN’s vacuum pressure process forces the protective ingredients all the way through to the core of the wood for virtually 100% penetration. We use a closed-loop, water-based system, which reduces volatile organic chemicals (VOCs) by 96% compared to the ordinary method of dip-treating wood in open vats of petroleum-based fluids. Our intense, vacuum pressure process also results in using less preservative to achieve an even greater level of effectiveness. The reliability of AuraLast wood is only available at JELD-WEN.
