MiraTEC Treated Exterior Composite Trim Boards

MiraTEC Treated Exterior Composite Trim Boards are engineered using the patented TEC™ process to deliver a solid, one-piece board with authentic woodgrain texture and uniform density, offering superior dimensional stability compared to hardboard alternatives. These boards resist moisture, rot, and termite damage—tested per ASTM D1037 and AWPA E7/E16 standards—to outlast competing products under harsh conditions. Backed by a 50-year limited warranty covering hail, delamination, fungal decay, termite damage, and excessive warping, they ensure long-term performance and peace of mind. Available in reversible 5/8″, 3/4″, and 1″ thicknesses, each board features a factory-applied light tan primer on one face and a cedar-textured or smooth finish on the reverse for versatile design options. Made from sustainable, post-industrial wood byproducts with no added urea-formaldehyde, MiraTEC is CARB-compliant and qualifies for LEED credits. Ideal for fascia, soffit, board-and-batten siding, window and door casings, and custom shutters, these trim boards handle like real wood while maintaining structural integrity through seasonal moisture cycles.
