CLT timber planks are engineered wood products made by bonding layers of timber together to improve stability, consistency, and performance. Cross-lamination helps reduce movement and creates a more predictable timber product for building applications.

Standard timber boards are cut from solid timber and can move more over time. CLT products are engineered to improve stability, helping reduce twisting, warping, and inconsistency across the build.

CLT is commonly used in walls, floors, and roofs in larger timber systems, but CLT-style planks are also relevant for interior lining, fencing, and outdoor project applications when they are designed for those uses.

That is one of their main advantages. Cross-laminated construction is valued because it improves dimensional stability and helps reduce the movement that often affects standard timber boards.

CLT is widely researched and promoted as a lower-carbon timber construction option because it uses wood from renewable resources and supports more efficient off-site production and assembly methods. Sustainability still depends on sourcing, manufacturing, transport, and product lifecycle.

Yes. Interior timber lining planks are commonly finished with paint, stain, oil, or clear coat, depending on the look you want. Smoother faces tend to suit paint or clear finishes, while more textured finishes are often chosen when you want the grain and saw marks to stand out more. Merchant fixing guidance also notes that high-quality coating systems should be used to the coating manufacturer’s recommendations.

CLT can be designed to meet fire performance requirements, but fire performance depends on the full system, including charring behaviour, linings, detailing, joints, and the tested or engineered assembly. It should never be treated as a simple one-line claim.
