Siding that won't shear off, tear, or become damaged during high winds and severe weather requires more than just strong materials. A strong fastening system that holds siding panels secure in extremely high winds is frequently what determines a product's success in locations that commonly, experience severe weather and high winds.

Many siding manufacturers have improved and reinforced their nailing hems and locking systems to ensure their products will stand up to some of the harshest, most damaging weather conditions. For most manufacturers, an improved and stronger nailing hem has been achieved by rolling the hem to double the material. Larger locks also contribute to the overall security of a siding panel.

"The roll-over nailing hem makes the vinyl twice as thick, so a nail has to tear through a double thickness of material," says Darvin King, senior vice president of sales, marketing, and distribution for Revere Building Products.

The full-roll nailing hem and Advantage Lock system on Revere's Sovereign 16 keep it firmly attached to exterior walls in winds as high as 198 mph. The extra-long vinyl siding comes in lengths of 16 feet 6 inches, reducing the number of seams (circle 109).

Rollex Corp.'s Winchester Bay vinyl siding uses a rolled nailing hem to provide extra strength and stability; the strong nailing hem also ensures proper nailing depth. Winchester Bay is rated to withstand wind velocities of up to 129 mph, according to Gary Heitsch, Rollex's manager of marketing services (circle 110).
