History of TruExterior
- Founded: 2013
- Founders: Boral
- Acquired by Westlake Corporation: 2021
TruExterior was developed inside Boral's North American building products operation as a higher-performance alternative to fiber cement siding. The core innovation was its poly-ash formulation: a composite blend of polymers and fly ash, the recycled byproduct of coal combustion, producing boards that resist moisture absorption, rot, swelling, and termites while remaining workable with standard carpentry tools.
The brand established itself in the 2010s as the premium composite option in the siding aisle, positioned against fiber cement leaders James Hardie and LP SmartSide and against wood and PVC trim products. Its moisture resistance made it particularly strong in wet climates and ground-contact-adjacent applications where fiber cement warranties exclude coverage.
When Westlake acquired Boral's North American building products businesses in October 2021, TruExterior became part of a portfolio with complementary strengths: DaVinci in roofing, Cultured Stone and Eldorado Stone in stone veneer, and Royal's vinyl siding lines. The combined business was rebranded Westlake Royal Building Products.

TruExterior Ownership: Pros & Cons
Advantages
