The patented nail-tight flexible hem is nailed securely to the wall. Each panel is suspended by 2,800 PermaFlex Suspension Cables, which are fusion-welded into a .088-inch double thickness of siding material.
SMARTWALL Technology can make a big difference in protecting homes from property damage during severe weather, says CertainTeed. Millennium brand vinyl siding has the only “won’t blow off” warranty in the industry, it says, and has been tested to withstand 270-mph winds.
Millennium-sided homes by Castle Home Builders in Hampstead, NC, survived Hurricane Bonnie in 1998, when winds of up to 104 mph damaged buildings and cut off power to nearly a half-million people.
Hurricane Floyd ripped through the same area in 1999 with 110-mph winds. Damage costs from Floyd alone were more than $1 billion. Builders and remodelers in hurricane-prone areas boast that they haven’t lost a single panel of Millennium during the relentless storms, according to CertainTeed.
