Ambara

  • Description: Ambara™, our thermally modified Ayous has an even caramel color due to the thermal modification process. Naturally durable and incredibly stable, thermally modified Ayous is a fantastic choice for siding, rainscreen, trim boards, pergolas and more.
  • More Info: Nova Ambara™, aka Thermally Modified Ayous, resembles a clear grade Aye & Btr Western Red Cedar in apearance. 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 apealing and lends itself well for a clear or walnut color stain. The thermal modification creates a qood 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 for hidden fasteners can be applied to create a complete hidden fastening look.
