Thermo-Treated Timber Decking

The Perfect Thermo-Treated Timber Decking Solution for British Weather

You’re probably no stranger to traditional decking materials warping, cracking, or rotting due to the UK’s unpredictable weather. This not only affects the look of our outdoor spaces but also makes us victim to frequent repair costs. Thankfully, we have developed a superior solution with our thermo-treated timber decking. 

Our high-temperature treatment process enhances hardwood’s natural durability and resistance, making it the perfect choice for a wet and variable climate. Enjoy a beautiful, long-lasting deck with minimal maintenance this year.

Problems Your Current Decking Could Be Causing

Warping, typical in traditional decking, occurs when moisture penetrates hardwood, causing it to expand and contract unevenly. Cracking follows as the wood dries out and contracts, leading to unsightly gaps and weakened boards. Rotting is another common issue, especially in areas with persistent dampness, resulting in decay and the need for frequent replacements.

The Round Wood Difference

The high-temperature treatment involved in creating our thermo-treated timber decking boards reaches temperatures of up to 200 degrees and up. This alters the wood’s cellular structure, removing organic compounds within the timber that are typically susceptible to moisture and decay. By doing so, it significantly reduces the wood’s ability to absorb water, making it far more resistant to the elements.
