Hurricane-Resistant Building Package Speeds Construction,
Attracts Homebuyers

This project included the following PATH-profiled technologies:

"That's an important designation, not just because it assures people that our homes are everything we say they are, but there's also a financial benefit to the homebuyer," Romig says. "In Florida, you get an insurance discount if it's a Fortified Home. Those discounts can range up to 70 percent for wind insurance. IBHS is also putting together a program with additional breaks on mortgages."

With R-16 insulation on exterior walls, R-30 roof insulation, and double pane, low-e glass throughout their homes, Tarpon Coast has also earned ENERGY STAR and FPL BuildSmart Certifications.

"Besides hurricane-resistance, these quality methods also translate into a tighter, more energy efficient home," says Romig.


"We use a building system. It's nothing that another builder couldn't do, but it's a combination of approaches that, when taken together, create an incredibly strong structure."

"First, we start out with precast concrete walls. When the manufacturer pours the walls, the concrete is guaranteed to test a minimum 5,000 pounds per square inch (psi). In comparison, the typical foundation slab is poured using 3,000 to 3,200 psi concrete. The walls themselves have been large-projectile wind tested to 235 mph. Basically, large 2x4s just bounce off them. At 5,000 psi, concrete is impermeable. So once that wall system goes up--even if you don't put an ounce of paint on it--you still won't get any water penetration through the walls. It eliminated the whole issue of mold build-up that we had after Charley."

"To top that incredibly strong wall system, the roof system consists of 5/8th-inch plywood that is both glued and connected with ring-shank nails in the strongest pattern possible. Then the roof itself is strapped to the wall system with hurricane ties to meet the 150-mph wind-zone requirement. Since the wall system is expansion-bolted to the foundation, in the end, you wind up with a single unit."
