Thermo Ash Cladding | T&G V-Joint/Nickel Gap Reversible (15 sq ft Bundle)

The Peak of Performance: Thermally Modified Ash

Thermo Ash represents the perfect intersection of nature and technology. Through a specialized heat and steam process (thermal modification), the sugars in the wood are caramelized, transforming traditionally light North American Ash into a deep, chocolate-brown hardwood with Class 1 Durability—the highest rating possible for wood longevity.

Key Aesthetic: "Crème Brûlée" Richness

Unlike surface stains, the thermal modification darkens the wood entirely through the core. It features a bold, expressive grain that brings a sophisticated, modern edge to any architectural project. If left untreated, it gracefully weathers to a stunning platinum-silver patina.

Why Choose Thermo Ash?

• Unrivaled Stability: The thermal process removes the wood's ability to absorb moisture. This means virtually zero warping, shrinking, or swelling, making it the most stable material for tight-seam architectural cladding.

• Sustainable & Chemical-Free: Sourced from sustainably managed temperate forests, Thermo Ash offers the performance of tropical "Ironwoods" but is processed without a single chemical.

• Optimal for Walls & Ceilings: It is significantly lighter than tropical hardwoods, reducing structural load and making it easier to handle for overhead soffits and vertical installations.
