Orlando, Fla. — Vinyl remains the most common cladding used to construct single-family houses, and both siding and decking manufacturers are giving homeowners new reasons to stick with the exterior wall material.
PlyGem expanded bold color options for the Mastic-brand vinyl siding line it unveiled in 2016 with a protective layer called SolarDefense. The proprietary formula uses a reflective technology to guard against fading and heat distortion, according to the Cary, N.C.-based building products manufacturer.
In addition, Azek Building Products promoted the use of Azek capped PVC decking as a cladding rain screen at the 2018 International Builders' Show, held Jan. 9-11 in Orlando.
Azek Building Products, a subsidiary of Azek Co., which is based in Skokie, Ill., says the new application has a wood-look curb appeal that needs no painting and sealing and won't mold, rot, stain or scratch.
"There's a very strong exterior design trend of architects and homeowners incorporating wood planks as accent walls on homes to add a warm visual," said Patrick Barnds, general manager of decking at Azek Building Products. "It's really a natural progression for us to make our premium decking available as cladding."
Formerly known as CPG International LLC, Azek Co. is the 10th-largest pipe, profile and tubing (PPT) extruder in North America with estimated sales of $360 million, according to Plastics News' ranking.
Azek says it is the first "leading" alternative decking maker to obtain a code compliance research report for using its products for residential cladding. Azek's decking lines called Vintage, Arbor and Harvest, which have more than a dozen colors combined, all meet requirements for cladding applications.
PlyGem has been investing in new technologies related to the trend toward darker colors in siding, James Brouillard, Ply Gem's product marketing director, said at the IBS. With estimated sales of $1.5 billion, PlyGem is the second-largest PPT extruder, the Plastics News' ranking shows.
Brouillard described SolarDefense as three layers of protection against the sun.
"We have a substrate that withstands high heat," he said. "Then, we have the capstock and then a third layer — a film that goes over it — that increases reflectivity and also helps control the heat. All these things combined give you a stronger siding and a siding that reflects more light. For us, it has been so successful that in just a few months we will launch the next generation of this product in a new profile."
