About Lunawood Decking

Lunawood ThermoWood® Decking combines the unmatched, authentic beauty of Nordic wood with enhanced durability and premium performance. Made in Finland from renewable Nordic Spruce and Pine, this premium decking is modified using only heat and steam. The result is a highly sustainable, completely chemical-free, and non-toxic product that is entirely safe to touch - perfect for both private homes and high-end public projects.

Thanks to its resin-free structure and low thermal conductivity, Lunawood remains exceptionally pleasant underfoot, staying cool even under the hot sun. It is engineered to perform reliably in all climates without warping or twisting over time. Left untreated, it beautifully weathers into a natural silver-grey tone without losing its decay resistance. Alternatively, you can easily maintain its rich, original brown hue with regular applications of a pigmented wood oil such as Osmo Oil.

No face-screws, no splitting wood, and no guesswork. The SecretFix installation kit is engineered to dramatically cut down your build time while automatically ensuring a perfectly uniform finish across your entire deck.

Key Facts

Origin: Proudly engineered and made in Finland from 100% renewable and sustainably managed PEFC/FSC-certified Nordic forests. 

100% Non-Toxic & Safe: Modified using exclusively high temperatures and water steam. Absolutely zero toxic chemicals, plastics, or heavy metals are used, making it completely eco-friendly and safe for children and pets. 

Unbeatable Stability: Swelling and shrinkage are virtually non-existent compared to traditional kiln-dried softwood or hardwood species. The boards retain their shape flawlessly across freezing winters and hot summers without cupping, twisting, or bowing. 

Splinter & Crack Resistant: Because the wood fibers are modified at a cellular level, Lunawood experiences drastically fewer splinters and deep structural cracks over its lifespan compared to standard pressure-treated lumber. 

Resin-Free: The high-heat modification process completely breaks down and evaporates all natural resins and saps. You will never have to worry about sticky sap bleeding through your surface oil or staining your outdoor furniture.
