The 90mm x 9mm board is available in 2.4m and 3.6m lengths, and is used for walling and ceiling applications. The 90mm board is available in our Satin UV range, and is a superior coating. As the timber lining board is prefinished, there is no further finishing required after installation! The Satin UV range is a low-VOC UV-coated finish available in natural and designer colours, with a contemporary satin finish. The Tongue and Groove profile is easy to install, and is lightweight making installation a quick process. The 90mm board has a matching Quad and Coverstrip trim to cover the expansion joint and is a great finishing detail.
