More about this product

Lunawood is an outstanding decking material due to its stability and durability. Improved insulation properties make it an excellent choice for decking since it balances the changes of heat and cold and makes it pleasant to walk on even when barefoot. Lunawood decking is resin- and toxic-free, lightweight, and easy to install.

It is made from LunaThermo-D, a type of Thermowood; a beautiful, sustainable wood material produced using natural methods; heat and steam. It is dimensionally stable, resistant to decay and non-toxic. Lunawood produces Thermowood from Scandinavian PEFC-certified pine and spruce from Finland. It can be used inside or outdoors, in any climate. Lunawood is an eco-friendly natural product that is easy to machine and install.

Wide decking boards can be produced by using glue lamination technology. Lunawood is able to offer 210 mm wide sound knotted deck boards with hidden PROFIX fixing due to thermal modification and gluing. The dimensional stability and bending strength are exceptionally good.


Due to the high temperature of Thermowood treatment process, resin is removed from the wood. This ensures high visual quality for both uncoated and coated LunaThermo-D claddings. The color of the wood is affected by the treatment temperature and time – the higher the temperature the darker the appearance.

Lunawood is available as factory oiled; two coats of pigmented wood oil are applied in a controlled factory environment creating an even coating and consistent color tone. The product is ready to be installed and does not require an immediate coating to secure color preservation.

As with all softwoods, variances occur and are due to varying densities. When the product is exposed to UV-light, it will turn beautiful silver grey unless protected by a pigmented surface protection.

Lunawood’s unique PROFIX hidden fixing clip enables quick and easy installation of the deck and creates a clean and elegant appearance without visible screws.


The D in LunaThermo-D stands for durability. Along with appearance, biological durability is a key property in the end-use applications of products in this treatment class. The tangential swelling and shrinkage due to moisture are low.

Average tangential swelling and shrinkage 5-6%
EN 113 standard classification Durable (class 2)
