ASH TIMBER DECKING
Ash Decking – A Premium Year-Round Addition to Your Garden
Thermo-treated ash decking is crafted through a specialised process that involves heating and steaming the wood to enhance its natural properties. This treatment increases the wood’s durability, stability, and resistance to environmental factors, making it an ideal choice for outdoor applications and year-long use with minimal intervention. It also features a rich, dark finish with beautiful grain details, providing an elegant and timeless look for your garden at any time of year.

Why Does Ash Make a Good Thermowood?
Ash is an ideal material for making Thermowood decking for several reasons:
- Durability: Ash is already an inherently durable, dense, and naturally resilient hardwood, which is only enhanced after thermal modification.
- Aesthetic Appeal: Ash retains its attractive appearance even after thermal modification, making it suitable for both functional and aesthetic applications in cladding and decking.
- Thermal Stability: Ash wood exhibits good thermal stability, meaning it can withstand the high temperatures required for the Thermowood treatment without compromising its structural properties. This stability ensures consistent and predictable results during the modification process
- Environmental Benefits: Ash wood is considered a sustainable choice for Thermowood production due to its availability and renewable nature. The process itself is environmentally friendly as it requires no chemical additives, aligning with eco-conscious building practices.
How Ash Decking Benefits Your Home

Withstanding Unpredictable UK Weather
The UK’s wet climate can cause untreated wood to warp, decay, and deteriorate quickly. Our thermo-treated ash decking undergoes a thorough heat and steam process that significantly enhances its durability and stability. This treatment makes the wood highly resistant to moisture, preventing warping and decay.

Hassle-Free Enjoyment of Your New Deck
Thermo-treated ash decking is the ideal solution when looking for low-maintenance outdoor spaces. The treatment process not only strengthens the wood but also removes resin, reducing the likelihood of splitting and cracking. This means you spend less time on upkeep and more time enjoying your deck.

An Eco-Friendly Choice for Homeowners
As environmental concerns continue to grow, more homeowners are seeking sustainable building materials. Our ash decking is sourced from well-managed forests, ensuring that the wood is harvested responsibly. The treatment process to make Thermowood is also chemical-free, making it an eco-friendly choice for your home. By choosing our ash decking, you are not only investing in a high-quality product but also contributing to a more sustainable future.

Beautifying Your Outdoor Space
A visually appealing deck can significantly enhance the overall look of your outdoor space. Our thermo-treated ash decking boasts a dark, rich finish and outstanding grain detail, offering an elegant appearance that complements a variety of architectural styles. Whether you prefer a modern or traditional aesthetic, ash decking provides a timeless beauty that enhances the charm and value of your home.

Simple Installation
Installation ease is key to quicker enjoyment of your new decking. Thermo-treated ash is about half the weight of heavier hardwoods like Ipe, making it easier to handle and install. This lightweight nature is particularly beneficial for rooftop terraces and elevated structures, where heavier materials might pose challenges. Our ash decking offers a practical solution that simplifies the installation process without compromising on strength or durability.
