TruExterior – The Next Big Breakthrough In Building Materials

The unique poly-ash technology used in all TruExterior Siding & Trim products was developed in our Innovation Factory. In the late 2000s, Boral engineers discovered a proprietary blend of polymers and fly ash that yielded outstanding results in durability, dimensional stability, moisture resistance and workability. It’s a game changer in raw materials that created a new product category in the exterior cladding market.
