Benefits

Weather-Resistant

Modified through a high-heat, chemical-free process, Ayous gains exceptional resistance to moisture, decay, and temperature swings.

Low Maintenance

Its improved dimensional stability means fewer splits, checks, or warps—delivering lasting performance with minimal upkeep.

Sustainably Sourced

Thermal modification uses fast-growing, responsibly harvested softwoods like Ayous, as well as zero chemicals, reducing pressure on endangered hardwoods.

Design-Forward

With a smooth, refined grain and warm, modern tone, Ayous brings a sleek, contemporary feel to exterior cladding and soffits.

Easy to Install

Lighter than tropical hardwoods and easy to cut or fasten, thermally modified Ayous is ideal for streamlined installs and custom detailing.

Fade and Stain Resistant

The thermal process darkens the wood through and through—giving it a rich tone that holds better over time and takes finishes evenly.

The best place to get Brazilian hardwood that I’ve found anywhere in California or online. The customer service is very good, the reps are attentive to you upon arrival and they are very knowledgeable. The quality of wood is superb and the pricing is cheaper than I can find anywhere else.

Absolutely the best place in socal for all of your tropical hardwood needs. Just built a small deck with 5/4 x 6 cumaru sourced from BL. Their prices can’t be beat locally. The selection is also great. They have all the major hardwood species.

Had a great experience with George the sales rep. He was very knowledgeable and honest. We ended up buying some thermally modified ayous panels for an outdoor media wall. So far so good. It looks great and hopefully will last for decades. (I sealed it with Cutek Extreme so hopefully that prolongs the lifespan). Thank you George!! Everyone has told us how much they really like the cladding used for our media wall and we appreciate your help with our project.
