Thermo Treated Ash (TTA) decking is an enhanced decking type that is highly resistant to insects & water. The decking species is Ash wood – Which goes through a thermal modification process that alters the wood’s chemical and physical properties.
The timber is effected on a molecular basis, which makes it superior regarding weathering, insect resistance and natural timber movement. This limits the ability of the wood to absorb moisture, so products are more dimensionally stable and less prone to cup, warp and twist with changes in humidity. The thermal modification process also removes the nutrients in wood that would otherwise provide a food source for insects and wood-destroying fungi. This increase in dimensional stability and decay resistance significantly extends the service life and reduces maintenance needs of the decking. Given these qualities, Thermo treated ash decking can be installed by a coastal environment or inland with no compromise on it its aesthetics, or quality.
