Thermory in Exterior Design: Decking

Thermowood decking is valued across the world for its great looks, durability, and low maintenance. Not to mention the chemical-free production process that only uses heat and steam to enhance the performance of natural wood. 

What’s so great about thermowood decking? 

Deckings, especially in public spaces, get a lot of foot traffic. That means it has to be durable. There are not many natural materials that offer the kind of expected lifespan as thermally modified wood does.  

Thermal modification is a chemical-free process that uses only heat and steam to modify wood. During this process, the wood’s moisture absorption lowers. Therefore, the boards twist, cup, and bend less than untreated wood in outdoor use, with less shrinkage and expansion. This dimensional stability allows for even the most intricate decking patterns to stay straight and beautiful. 

Beyond durability, thermowood decking is remarkably low maintenance. Besides regular cleaning, it doesn’t require much. While oiling or coating can preserve the rich brown color, it’s entirely optional. The wood naturally weathers to a beautiful silver-grey without losing its structural integrity.

Residential home decking

When choosing materials for the home, people often look for natural and sustainable materials. Thermal modification uses only heat and steam to enhance the wood, no chemicals needed. 

The surface of thermowood is very smooth and hidden fixing ensures that there are no visible screw holes, making the decking barefoot safe and pleasant to walk on.  

For residential projects, many opt for thermally modified pine as it is beautiful, durable, and reasonably priced.

Rooftop terraces

Rooftop terraces are becoming increasingly popular as people seek out their own patch of greenery in the urban landscape. Often, these spaces are fully exposed to sun, wind, and rain, demanding resilient materials. Thermowood decking, particularly thermally modified ash, is a perfect fit. It’s lightweight, easy to cut on-site, and quick to install. The same material can be used across decking, planters, windscreens, and benches for a cohesive look.

Public buildings’ decking

In public spaces, durability is a must. Compared to other natural materials, thermowood decking offers a long lifespan with minimal maintenance. Creating inviting outdoor spaces with warm ambiance (as wood does), brings human scale to otherwise large spaces.  

Additionally, hidden fixing provides a sleek, clean look suitable for many architectural styles.

Pool decking

Few natural materials are as well-suited to pool areas as thermowood. It doesn’t overheat under the sun, and its smooth surface feels comfortable underfoot. The wood’s natural resistance to moisture and its ability to maintain shape make it an ideal choice for pool surrounds.

Small balconies

Installing wood decking on small balconies is easy with modular wood decking tiles. With no substructure, tools or even screws required, decking modules can be quickly and easily connected with the help of weatherproof plastic supports.

Public walkways and parks

Walkways, piers, and terraces in parks need to handle heavy use and unpredictable weather. Thermally modified wood has excellent durability, ash being in durability class 1 (25+ years’ protection against wood decay) and pine in class 2 (15+ years’ protection against wood decay). 

Thermowood weathers to silver grey color quite fast when exposed to sun, but that doesn’t affect its durability. Many architects embrace the natural weathering as part of design.
