Building products maker CertainTeed Corp. launched a national rollout for a polyurethane composite siding that it calls "revolutionary" and claims can offer unmatched moisture resistance in a wide plank that resembles cedar.
Named Icon, the siding is manufactured in Jackson, Mich., with a proprietary formula of glass fibers and a fly ash mix of quartz and iron mineral dusts. The result is a premium product, according to Kelly Warren, marketing manager for CertainTeed Siding.
"Our engineers created a revolutionary, unique premium cladding," Warren said in a phone interview. "Homeowners like the rich texture, wide flat face and shadow lines. Builders like that its lightweight and easy to install."
Icon siding comes in extended 16-foot-long panels but is light enough that one person can carry up to five panels at a time and install them in a few steps.
CertainTeed began a slow roll-out of Icon in the Midwest in 2016 but it is now available nationwide and will be featured at the 2018 International Builders Show in January.
Founded in 1904 and based in Malvern, Pa., CertainTeed also produces roofing, fences, decking, railing, trim, insulation, dry wall and ceilings. The company and its affiliates saw sales of about $3.4 billion in 2016.
In the most recent Plastics News' ranking, CertainTeed was No. 5 among pipe, profile and tubing extruders in North America with estimated related annual sales of $640 million.
While Icon production has an extrusion component, Warren said the siding is manufactured with a "belt process."
Icon siding comes with a 30-year warranty and is being positioned as a high-performing alternative to fiber cement and composite wood. Warren said it is typically higher priced than both.
"This is our first true composite siding. This is something completely different," Warren said. "Because it's a polyurethane thermoset product, you don't get moisture absorption like you do with a wood composite or fiber cement. That performance feature is unique to a plastic composite product and it lends itself to a host of benefits."
Among those benefits, Warren said Icon won't delaminate or contract and expand on the wall, which means it doesn't need flashing to prevent water from getting behind the siding and compromising the house wrap or exterior wall structure. Icon can also be installed without caulking.
"If you look at the way fiber cement and wood composites have been positioned, they've always been mid- or upper-tier products," Warren said. "But, you've got moisture absorption and expansion and contraction on the wall."
Polymer composites are next-generation products, Warren added. She said CertainTeed expects strong sales for Icon at the expense of wood composites and fiber cement.
