Will your windows survive a 34 mph projectile?
In short: General contractor Tom Silva demonstrates the varying effectiveness of different window protection methods, from plywood to impact-resistant glass, to help you prepare for storm-driven debris.
The video evaluates several defense layers against flying objects. Although 5/8-inch-thick plywood resists a 2x4 moving at 34 miles per hour, OSB of the same thickness fails to do so. Other options include resin-treated ballistic nylon, which prevents debris from entering the home but does not prevent the glass from breaking, and metal storm shutters, which may bend inward and crack the window if struck in the correct spot. Finally, impact-resistant glass is shown to shatter upon impact without breaking apart or allowing the window to crack open.
