Wind valves will help increase hurricane resistance on Florida schools
Wind valves that harness the force of swirling winds to keep the roof in place during storms will be used to help seven Florida school roofs withstand hurricane-force winds. The schools in Seminole County, Fla., will be renovated under roof-replacement contracts worth more than $2 million. The resilience of a wind-vented roof has already been proven at the Miami International Airport. The valves can only be used on flat or low-slope roofs.
