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 30-year limited warranty. 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 mildewicide. The product has no added urea formaldehyde.
CraftMaster molded door designs, MiraTEC trim and Extira panels have no added urea formaldehyde. This is certified by Scientific Certification Systems under certificate number SCS-MC-01802. They are manufactured with environmentally preferable phenolic resins. In addition, CraftMaster Green Doors contain no added urea formaldehyde.
