Transform Your Outdoor Living Space with Thermally Modified Wood

Is your decking losing its allure? Your soffit showing signs of wear? Maybe your panelling seems outdated? Thermally modified wood could be the game-changer you’ve been searching for. Picture a wood finish that’s both luxurious and durable. While traditional wood may succumb to nature’s elements, leading to premature wear or lackluster aesthetics, thermally modified wood endures. Discover the transformative capabilities of thermally modified wood. It’s reshaping the approach to decking, soffit, and panelling designs.

We are proud distributors of registered THERMOWOOD manufactured by Thermalwood, Lunawood, and Scottywood.

What Is Thermally Modified Wood?

The wood undergoes a thermal modification process that collapses its cells, removes extractives, and increases density. Turning the wood into a stronger, more reliable version of itself. Making it virtually impervious to warping, rotting, humidity fluctuations, and splintering. Since the procedure doesn’t involve any nasty chemicals, the resulting wood is completely natural and environmentally friendly.

Hardy and dimensionally stable, it’s a dream to work with for both exterior and interior decking, soffit, cladding, and panelling. Promising minimal maintenance over an incredible lifespan.

Why Thermally Modified Wood is a Game Changer

Thermal modification bestows a rich, deep allure upon the wood, which can be maintained with an oil-based UV-protectant stain. If left unprotected from UV exposure, the wood naturally ages into a beautiful silver/gray patina — rivaling that of exotic and tropical hardwoods.

DIMENSIONALLY STABLE — Enhanced density and durability for a harder wood with greater longevity.

DECREASED TENSION — Reduced moisture absorption makes it less prone to warping, cupping, or twisting.

REDUCED EXPANSION — Excels in fluctuating humidity environments with minimal expansion.

ROT RESISTANT — Resistant to insects, wood rot, and fungal growth.

PAINT DURABILITY — Improved paint durability, less flaking and peeling.

ENHANCED INSULATION — Keeping decks cool in summer thanks to lower thermal conductivity.

LOW MAINTENANCE — Buttery-smooth finish that’s splinter free, lightweight, and easy to work with.

Sustainable & Eco-Friendly

The thermal modification process doesn’t use any toxic chemicals. Ensuring the wood won’t contaminate the soil and environment. Compared to unmodified wood, thermally modified wood has also been shown to emit significantly fewer terpenes, camphene, and other compounds.

Boasting enhanced stability and durability this prolongs its life and minimizes the long-term maintenance required to keep the wood in prime condition.
