We’ll examine the benefits of both impact windows and hurricane shutters, and provide you with the information you need to make an informed decision on how best to protect your home during hurricane season.
What Are Impact Windows?
Definition of impact windows
Impact windows, also known as hurricane windows, are specially designed windows that are built to withstand the impact of strong winds, hurricanes, and other extreme weather conditions. These windows are constructed using multiple layers of glass and a durable interlayer material, such as polyvinyl butyral (PVB), which keeps the glass intact even if it breaks under pressure. The frames of impact windows are typically made from strong materials like aluminum or vinyl, further enhancing their ability to withstand powerful forces.
How impact windows protect against hurricanes
The main purpose of impact windows is to provide protection against hurricanes and other severe weather events. During a hurricane, strong winds can create high-pressure zones near the windows and doors of a building. Regular windows are susceptible to shattering under these extreme pressures, which can lead to catastrophic damage to both the property and its occupants.
However, impact windows are specifically designed to withstand these forces. The multiple layers of glass and the interlayer material in impact windows provide a barrier against high-pressure winds. Even if the glass cracks or breaks, it will remain intact and securely held together by the interlayer, preventing the destructive force of the hurricane from entering the building.
In addition, the durable frames of impact windows are bolted securely to the structure of the building, further reinforcing their ability to resist high winds and impact from flying debris. This structural integrity helps to ensure the windows remain in place, preventing the hurricane from creating breaches in the building envelope and reducing the risk of significant damage.
