CHICAGO -- CraftMaster Manufacturing Inc. (CMI) announced today it has increased the warranty period for its MiraTEC® Treated Exterior Composite trim from 30 years to 50 years, as a result of independent weatherability testing. The new 50-year warranty takes effect immediately and continues to cover hail damage, delamination, decomposition due to fungal growth, splitting and cracking, excessive swelling and buckling, as well as damage from termites. No fiber cement, OSB, or fiber substrate/hardboard trim product available offers this level of protection.
Unlike warranties offered by competitive products, the new MiraTEC warranty does not require registration with the manufacturer (CMI), and it is valid for the original purchaser plus two other homeowners of the structure to which the trim was applied.
Since its introduction to the residential and commercial building markets in 1999, MiraTEC has become a trusted alternative to hardboard products for exterior trim applications by new home builders, remodelers and do-it-yourselfers. In addition to its track record of success and longevity, MiraTEC recently outperformed all brands of hardboard trim in a Weatherability test conducted by an accredited third-party testing agency.
Performed in accordance with ANSI A135.6 (2006), the Weatherability test subjected MiraTEC and three other trim samples to six cycles of water soaking, heat/freeze and humidity changes to assess their ability to withstand exposure to the elements. The test calculates the residual or remaining thickness swell of the trim products to measure water absorption.
The extensive testing revealed MiraTEC trim exhibited the lowest percentage of residual swelling of all exterior trim samples. MiraTEC performed more than nine times better in long-term performance (see chart below) than one hardboard trim sample, over six times better than another and nearly three times better than the third sample tested.
"A strong warranty is a critical factor in the selection of exterior trim products, and the new 50-year warranty for MiraTEC trim provides builders, remodelers and homeowners with peace of mind that their purchase decision is backed by a comprehensive performance guarantee," said Bob Merrill, CMI president and CEO. "Swelling of exterior trim is a chief concern for builders and remodelers. As this test clearly shows, hardboard trim products have a greater tendency to swell when exposed to the elements, compared to MiraTEC."
MiraTEC is an engineered wood trim that is manufactured as one solid piece with uniform density and thickness; it is not two separate pieces laminated together like hardboard trim products. MiraTEC features a reversible, wood grain texture on one side and a contemporary, smooth finish on the other, which offers great design possibilities for decorative trim, gables, board and batten applications, dentil trim, corner posts, porch trim, roofline fascia, window and door trim, and similar architectural components. It also provides the perfect accent to any exterior cladding.
MiraTEC trim is created using CMI's patented and proprietary TEC manufacturing process that was developed specifically to make trim. This sealed press, steam-injected process creates a trim board that is one solid piece. During manufacturing, wood fibers and other ingredients are bonded under heat and pressure, combined with phenolic resins for moisture resistance, and treated with zinc borate, an EPA-registered wood preservative, for added protection against rot and termite damage. MiraTEC trim has no knots or voids like wood, so it eliminates waste. Plus, it accepts paint beautifully and is not prone to thermal expansion.
