Performance
Made from the patented TEC™ process, MiraTEC^® Treated Exterior Composite trim combines the eye-catching beauty of cedar with the long-lasting performance of an engineered product. Because it is not hardboard, MiraTEC trim will not delaminate, is moisture, rot and termite resistant, and is backed by a 50-year limited warranty.

Moisture resistant: As measured by ASTM D1037 for water absorption and thickness swelling. Rot resistant: Tested per AWPA E16 Field Test for Evaluation of Wood Preservatives to be Used Out of Group Contact: Horizontal Lap-Joint Method. Termite resistant: As measured by AWPA E7 Standard Method of Evaluating Wood Preservatives by Field Tests with Stakes.

Innovation
Treated with zinc borate; moisture, rot and termite resistant MiraTEC trim excels in all four seasons. Because MiraTEC trim is specially treated, it's more cost-effective over time than redwood, cedar, fir or poplar. MiraTEC trim lasts longer and holds paint better. It is factory-primed on four sides with a low VOC primer with a mildewcide.

Thanks to CMI's patented TEC manufacturing process, MiraTEC trim is uniformly thick and dense, with no voids or knots. Any way you use it, MiraTEC trim provides maximum yield, eliminates waste, and offers a plentiful product supply and stable pricing.

Beauty
MiraTEC trim looks just like real wood — only better. Combining beauty with the best in technology and performance, MiraTEC trim helps you achieve a distinctive look for the long term.

MiraTEC trim provides the perfect accent to any exterior cladding – cement fiber, vinyl, brick, OSB, hardboard, wood or stucco. You have the option of a smooth side and a textured side for maximum versatility. It’s factory primed with a mildew-resistant primer on four sides for easy painting. MiraTEC trim presents wonderful possibilities for dentil trim, gables, corner posts, porch trim, fascias, windows, doors, column wraps, decorative trim and other non-structural architectural elements.
