Woods
Extira panels are an exterior grade, treated wood composite panel that provides a combination of moisture, rot and termite resistance not possible with MDF, plywood and wood. It offers high performance with low maintenance in a wide range of non-structural, paint-grade applications. Extira panels machines well, allowing those who work with it to easily sandblast, rout, carve, laser engrave, prime, paint and adhere other materials to it.
Extira panels have quickly gained acceptance as an excellent material for architectural millwork. Typical applications include fluting, rosettes, dentil mouldings, shutters, brick mould, column wraps, pilasters and exterior trim. It is used for door and window parts; garage doors; outdoor signs; playground equipment; subflooring; marine, landscape and nursery applications; and a host of other specialty and decorative needs. Extira panels also excel in high-moisture interior applications, such as areas around dishwashers and sinks. Today, home builders, remodelers and architects are among those who value its long-term exterior performance, durability and low maintenance.
Extira panels are composed primarily of wood and are manufactured using hardwood chips - often the byproducts of sawmilling operations. The composite panels are manufactured by CMI with its TEC sealed press, steam-injection manufacturing technology, as opposed to the open press technique used to create hardboard and MDF.
Unlike MDF, Extira panels are ideal for exterior applications, because they resist moisture, rot and termites. Compared to wood, Extira panels feature higher yields, board consistency, more stable pricing and wide availability. They are gentle to the environment and have no added formaldehyde.
Extira panels are also made from sustainable materials. No old growth wood is used to create Extira panels; they are made from wood that is of no commercial value. Additionally, Extira panels have no added urea formaldehyde. This is certified by SCS (certificate number SCS-MC-01802). Through repeated testing by the Composite Panel Association, a third-party certifier for the CARB's ATCM 93120 rule, Extira panels have demonstrated formaldehyde emissions equivalent to background levels found in the environment.
Extira panels are available in 1/2", 5/8", 3/4", 1" and 1-1/4" thicknesses, and come in three, unprimed panel dimensions of 4'x 8', 4'x 16' and 2'x 16'. Extira panels are backed by a five-year limited warranty.
Environmental Manufacturing Process at the heart of all CMI products is a commitment to an environmentally responsible manufacturing process.
Wood Sources:
No old growth timber is harvested to make CraftMaster, MiraTEC or Extira products, and all wood comes from an area within a 200-mile radius of CMI's manufacturing facility in Towanda, Pa.
Types of wood sources include sawmill chips and field chips.
The wood used in CMI's manufacturing process is of no commercial timber value and is the byproduct of other operations. Sawmill chips are residual waste from sawmilling operations. Field chips, which are the byproduct of sound logging practices, are the residuals from field chipping operations of tree tops and leftover wood.
Left unused this wood would simply rot or be sent to landfills. Removing this wood source allows mature trees to grow. Instead, it is broken down into fibers, and then exposed to intense heat and pressure as it is converted into engineered wood products.
Primer:
CraftMaster molded door designs and MiraTEC trim are primed with a low VOC primer. This is among the most environmentally preferable of all finishes available on the market.
No Added Urea Formaldehyde:
Due to their physical composition, CraftMaster molded door designs, MiraTEC trim and Extira panels are not subject to the CARB's ATCM 93120 rule. This measure enforces limits on formaldehyde emissions from most composite wood products.
If they were subject to the ATCM, all CraftMaster molded door designs, MiraTEC trim and Extira panels would meet the specification for the designation "ultra low formaldehyde emitter."
CraftMaster molded door designs, MiraTEC trim and Extira panels have demonstrated formaldehyde emissions equivalent to wood through repeated testing by the Composite Panel Association.
Wood composite products that do not contain urea resins, such as the family of CMI products, are recognized in the building products industry as meeting the strictest formaldehyde emission levels. They can also contribute to industry programs that include LEED® for Commercial Interior, LEED for New Construction and Major Renovations and NAHB - National Green Building Standard™.
