Building Reinforced Concrete Storm-Ready Homes in Florida
Bob works with Scott and Aaron Renfroe to install impact-resistant windows and sliding doors.
Clip Summary
Aaron Renfroe from Great Southern Windows installs the PGT WinGuard windows as Bob looks on. He first applies a thick bead of polyurethane caulk to the flange on the window frame. Bob points out the cast concrete lip on the window buck that will provide a solid surface behind the frame to prevent blow-ins. The caulked edge of the frames lays up against the concrete lip to make a very tight seal. These heavy windows are held in place with long masonry screws, called Tap Cons. Since Hurricane Andrew, stringent codes have required longer screws that are drilled right into the block or concrete.
