Thermal Gain on Decks

Thermal gain on decks and terraces is a particular issue in the summer season. A thermogram image analysis was conducted in Japan with the Hiroshima Prefectural Technology Research Institute to assess the differences between Accoya® wood, thermally modifies wood and three variants of commercial WPC decking.


The thermograms clearly indicate that thermal gain in Accoya® wood decking is substantially less than the alternatives tested.

In its natural form, Accoya® wood is a cream/light straw colour. From a technical performance perspective, in respect of attributes such as durability and dimensional stability, there is no need to finish Accoya® wood decking. However, like any natural wood species, Accoya® decking is susceptible to weathering in exterior circumstances and therefore can exhibit various types of discolouration such as moulds and uneven UV weathering.


Accoya® wood has a very high resistance against rotting, making it a popular choice to use uncoated. It can be left to weather naturally and over time, will eventually turn a silvery-grey colour. The grey surface colour of unprotected wood exposed to outdoor circumstances is caused by UV. The rate of weathering of Accoya® timber decking will vary as the higher the amount or intensity of UV the surface is subject to, the faster this process will develop.
