Thermally Modified Wood Decking vs. Composite and PVC: What’s the Best Choice for Your Project?
Thermally Modified Southern Yellow Pine
The decking industry has seen an explosion of options over the last 15 years, with materials ranging from pressure-treated lumber and tropical hardwoods to modern composite and PVC alternatives. While each decking material has its own set of benefits, thermally modified wood has emerged as a compelling option for those who appreciate the warmth of real wood while demanding enhanced durability.
At Intectural, we are proud to be the distribution partner for Arbor Wood Co., a leading manufacturer of thermally modified wood. But how does this natural material compare to industry giants like composite and PVC decking? Let’s break it down.
Durability & Maintenance
Thermally Modified Wood – Through the thermal modification process, wood becomes highly resistant to rot, decay, and insect damage. While it’s more durable than untreated wood, periodic maintenance such as sealing or oiling may be needed to preserve its appearance.
Composite Decking – Known for low maintenance, composite decking resists rot, decay, and insect damage. However, exposure to extreme temperatures and UV radiation may cause some fading or warping over time, without the option to refinish.
PVC Decking – Highly moisture-resistant and impervious to mold, mildew, and insect damage. PVC decking holds up well in humid or waterfront environments but can become brittle in cold temperatures and may feel hot underfoot in direct sunlight.
Sustainability & Environmental Impact
Thermally Modified Wood – Sourced from sustainably managed forests, thermally modified wood is treated using only heat and steam, eliminating the need for harsh chemicals. This makes it an eco-conscious choice for those looking for a natural, renewable decking solution.
Composite Decking – Many brands use recycled wood fibers and plastics, but the manufacturing process can be energy-intensive, and at the end of its lifespan, composite decking often ends up in landfills.
PVC Decking – Made primarily from virgin plastic, PVC is the least sustainable option. Its production relies on fossil fuels and is non-biodegradable, meaning it may persist in the environment for centuries.
Aesthetic Appeal
Thermally Modified Wood – The heat modification process deepens the wood’s color, giving it a rich, exotic hardwood-like appearance. It maintains the warmth and authenticity of natural wood while offering a unique, high-end look.
Composite Decking – Designed to mimic wood, composite boards contain wood fibers and plastic. While some products achieve a realistic wood grain, they often lack the depth and authenticity of real timber.
PVC Decking – Typically uniform in color and texture, PVC decking offers a modern, sleek aesthetic. It’s a good choice for those who prefer a contemporary look, though it may lack the natural charm of real wood.
Cost Considerations
Thermally Modified Wood – With options available for most price points, thermally modified wood is a versatile choice that can fit various budgets. It is also readily available, making it an accessible option for homeowners and builders looking for a high-quality decking solution.
Composite & PVC Decking – Pricing varies significantly depending on brand, manufacturing process, species, and warranty options. It’s best to compare local pricing and consult a decking expert to determine the best fit for your budget and project requirements.
The Bottom Line: Which Decking Material is Right for You?
When selecting a decking material, consider the balance of aesthetics, durability, maintenance, and sustainability.
If you want the authentic beauty of real wood with enhanced durability, thermally modified wood is an excellent choice.
If sustainability is important, thermally modified wood offers an environmentally responsible alternative to synthetic options.
At Intectural, we believe that beauty, sustainability, and performance should go hand in hand. As the distribution partner for Arbor Wood Co., we offer premium thermally modified wood decking that delivers on both aesthetics and longevity.
