The Best of Lunawood ThermoWood® Decking
Lunawood ThermoWood® decking blends the timeless beauty of real wood with exceptional performance in demanding outdoor conditions. Produced in Finland using only heat and steam — completely free from chemicals, it is a safe and sustainable choice for modern outdoor living.
The thermal modification process enhances the wood’s dimensional stability, helping it maintains its shape even in hot and humid conditions. It is also highly resistant to decay, making Lunawood a smart choice for long-term outdoor use with minimal maintenance.
Lunawood decking features a beautiful, splinter-free surface, offering comfort underfoot — perfect for patios and terraces. When left untreated with pigmented wood oil, the surface will naturally weather into a silver-grey tone, adding timeless character for the decking.
Flawless Results with the Right Fixing and Installation
Lunawood’s hidden fixing systems are designed to deliver a seamless and secure installation experience. By avoiding visible screws, the focus stays on the natural beauty of the wood while enhancing long-term durability of the deck.
