DURATION® manufacturers all of its products from Westlake's TruExterior Trim and Siding materials. TruExterior is an entirely new category of building materials made with poly-ash, which addresses both the moisture- and movement-related issues commonly experienced with other exterior materials on the market. DURATION is the industry leader in moulding, millwork, beveled siding, and custom siding machined from poly-ash.
Because DURATION® mouldings are both moisture and termite resistant, they are particularly ideal for ground contact. DURATION® can be cut, routed and milled easily and will not rot, crack or split.
DURATION® products can be painted any color and don’t even need end-sealing or special adhesives. And because they are composed of over 70% recycled material, they are earth-friendly and green
