Lunawood Decking

Lunawood ThermoWood is genuine Nordic wood, pine and spruce from Finland, transformed through a patented thermal modification process using only heat and steam at 180-230 °C. No chemicals, resins, or toxic preservatives are added. The 40-hour treatment changes the wood cell structure, greatly improving dimensional stability, rot resistance, and long-term outdoor performance.

Lunawood is built for northern climates. It is made from trees that grew for nearly 80 years in Finnish forests, one of Europe's toughest environments. The thermal process greatly reduces the wood's moisture content, minimizing swelling, shrinking, and warping during Quebec freeze-thaw cycles.

Lunawood stands apart from other wood decking options because it is real wood with authentic grain, texture, and scent, not a composite imitating wood. The thermal process is completely natural, using only heat and steam, with no chemicals or toxic preservatives. It improves resistance to rot, insects, and weather while keeping the warm character of natural wood.

Pressure treated wood uses chemicals (often alkaline copper quaternary) to protect against rot. Lunawood achieves the same result—and better—using only heat. No chemicals leach into the soil or rainwater, making it a truly environmentally friendly choice. ThermoWood's dimensional stability is also significantly superior: it warps, swells, and shrinks much less than treated wood. The downside is a higher initial cost, but the 30-year lifespan, reduced maintenance, and absence of chemicals more than make up for it in the long run.

If you like the natural silver-grey look of aged timber, Lunawood requires no surface treatment—it will develop that patina on its own within a few months of outdoor exposure. If you prefer to keep the original warm brown tone, annual treatment with a pigmented UV oil is recommended. Regular cleaning with soapy water or a pressure washer (low pressure) helps maintain the appearance in both cases. Fine surface cracks are normal and do not affect the structural performance of the wood.
