Although the Atlantic Hurricane season is drawing to a close, and hopefully without a big finish, it's probably a good time to increase your knowledge about the importance of specifying ventilation products that can meet the challenges of future hurricanes and high winds. Louvers that are not able to withstand high wind loads, the impact of flying objects or wind driven rain can cause a lot of damage inside a building and be very costly to replace. That's why Greenheck offers nine individual louver products that have earned the Miami-Dade Notice of Acceptance and 14 louver models that have been Florida Product Approved.

In addition, all Greenheck Florida Building Code Approved and/or Miami-Dade Qualified louvers are AMCA 540 Listed and several Greenheck louvers are AMCA 550 Listed. Greenheck encourages design professionals to specify "AMCA 540 Listed" or "AMCA 550 Listed" when applicable rather than simply stating "meeting the requirements of AMCA 540 or complying with AMCA 550."
