Thermo Ash Decking (15 sq ft Bundle)

The Peak of Performance: Thermally Modified Ash Decking

Thermo Ash represents the perfect intersection of nature and advanced engineering for premium outdoor living spaces. Through a specialized heat and steam process, traditionally light North American Ash is transformed into a rich, chocolate-brown decking board with Class 1 Durability—the highest rating possible for exterior longevity.

Aesthetic: "Crème Brûlée" Richness Unlike surface stains, thermal modification deepens the color entirely through the core of the wood. The bold, expressive grain brings a sophisticated, modern edge to custom decks, patios, and boardwalks. If left untreated, your deck will gracefully transition to a striking platinum-silver patina over time.

Why Choose Thermo Ash for Your Decking Project?

• 20-Year Manufacturer Warranty

  Backed by a 20-year residential warranty against rot and decay, giving you lasting confidence in your investment.

• Unrivaled Stability: The thermal process fundamentally changes the wood's cellular structure, eliminating its ability to absorb moisture. This means virtually zero warping, shrinking, or swelling—delivering perfectly flat, tight-seam deck boards year after year.

• Sustainable & Chemical-Free: Sourced from responsibly managed temperate forests, Thermo Ash delivers the elite performance of tropical hardwood decking without a single chemical treatment.

• Optimized for Bare Feet: Highly resistant to rot and decay, it stands up flawlessly to the elements. The modification process also makes the decking less prone to splintering and heat retention, keeping it remarkably smooth and comfortable underfoot.
