Nova Ambara™, aka Thermally Modified Ayous, resembles a clear grade Aye & Btr Western Red Cedar in appearance. Ayous has an even cream color in its natural form but Nova's unique thermal modification process changes this to a caramel brown or tan color that is very appealing and lends itself well for a clear or walnut color stain. The thermal modification creates a grade that is extremely stable and durable - this is what makes Ambara the best choice in thermally modified wood. Ambara™ compares favorably with Western Red Cedar for use as trim boards, siding, cladding, pergolas and more. Ambara™ is a softer, light weight species making it ideal for installation on walls and ceilings. It can be nailed or screwed, and clips can be applied to create a complete hidden fastening look.
