Window film provides cost-effective storm security protection

With climatologists predicting above-average numbers of severe storms this summer, the non-profit International Window Film Association (IWFA) recommends the installation of window films for added glass safety and added benefits. depending on the product installed.
Window films permanently adhere to glass surfaces and are typically made of multiple layers of polyester strands with various engineered coatings added to improve their performance in solar heat rejection, glare reduction and 99% glare blocking. harmful ultraviolet (UV) rays.
Security window films can have similar characteristics, but they can be the thickness of two driver’s licenses stacked together or much thinner. In addition to the strong adhesive used to attach the film to the glass, a wet glazing system designed to lock the edges of the film to the sides of the window frame itself may also need to be added.
“What the film does is make glass less dangerous by helping to hold broken glass together, which can provide a barrier against wind and rain,” says IWFA Executive Director Darrell Smith. “If the wind persists for a long time after the glass has been broken, the repeated changes in wind pressure on the window system may cause the broken pieces of glass to eventually cause a tear in the film even if fragments are still held together on the window film.”
Glass can be dangerous because strong winds and debris flying through the air can cause it to shatter and release shards that can fly across a room and cause life-threatening injuries. Safety window films (to a lesser extent window films in general) make window systems more flexible and can hold broken glass shards in place when they remain stuck to the film. Similarly, during an intense hailstorm, large ice pellets can cause significant damage to unprotected glass.
“Window films are not designed or approved to be a hurricane protection product that meets the requirements of the State of Florida, but they are a cost-effective layer of security and can provide a barrier of protection during periods severe weather,” Smith added.
