We’ve started cladding the exterior with Weathertex Weathergroove, a product made by pulping down hardwood and then compressing it under extreme pressure (just like a diamond!). This creates a stable, solid product that’s formed into sheets with a good range of profiles and surface textures. I like it because it’s 97% natural hardwood, contains no resins, binders or added formaldehydes, so despite the bit of sawdust on her nose, site dog can breath easy! http://weathertex.com.au/product/weathergroove-smooth-150/
