Weathertex lightweight, natural timber exterior wall cladding systems are manufactured in NSW using an exclusive process found nowhere else in the world, so these weatherboards and architectural panels occupy a unique position in the marketplace. Hardwood timber is chipped, pulped and pressed with 3% natural wax to produce manufactured timber products that are altogether natural – no chemical additives.

Weathertex is made from PEFC certified state forest or private hardwoods from controlled sources, and leaves a better than zero carbon footprint on the environment. Having gone through a rigorous evaluation process to determine their “green performance”, Weathertex offer the very first manufactured product to receive Platinum GreenTag™ certification worldwide. Weathertex Selflok Ecogroove can be used both internally and as an external wall cladding in bushfire attack levels up to and including BAL 19 construction.
