Why Are Storm Shutters Needed?
The report explains that shutters remain an important part of a hurricane-resistant home because they provide protection for glass doors and windows against windborne debris. Another important reason that shutters should be used is that they keep the building envelope intact (i.e., no window or door breakage). During a major windstorm this is vital to the structural integrity of the building. When the envelope is breached there is a sudden pressurization of the interior which can cause major structural damage (e.g., roof loss). The structural damage, if even to a minor degree will then lead to a third potential damage factor: water intrusion. Water intrusion, caused by water driven rain, will cause significant interior and contents damage. It has been found to be the most costly of all three of these types of damage from storms.
