How to prevent glass from breaking?
Even the highest design pressure does nothing to prevent glass from breaking due to impact as objects fly around in high winds. To prevent breakage from impacts, look for impact-resistant glass, which is specially designed to hold up to impacts from flying debris. Impact-resistant glass can withstand the impact of a missile traveling at 34 miles per hour, according to CNN. If your windows are not impact-resistant, cover them with plywood or storm shutters to reduce the risk of breakage during high winds.
