Please Note:

PermaTimber® contains natural timber elements. As you would be aware, timber has different natural appearances, and to ensure PermaTimber® does indeed look like timber, it may also experience similar variations in colour, tone, and grain. As a result of this Perma Composites® may have natural variations in each decking board and in some instances a slight difference between sample and final colour. 

Should you have a large project, it is recommended that all requirements are ordered at once to avoid any chance of colour variances.

The customer/installer is responsible for inspecting each decking board for colour, finish, size, and other issues prior to installation.
