Impact glass is designed to resist impact-based damage, which is why it first became popular as a car windshield. Such impact glass is constructed to sustain heavy wind gusts of up to 200 mph and its miscellaneous debris. For this reason it’s becoming highly favorable for homeowners in hurricane zones.
Impact windows are designed with three layers. The outer layers are constructed of glass while the inner layer consists of polyvinyl butyral (PVB). When all three of these layers are fused together via heat and pressure, or lamination, these layers become stronger and more durable. The result is an impact window.
Does impact glass break?
So, does impact glass break? The short answer is yes, impact glass can break.
However, as these glass panes receive and impact, the inner layer of PVB keeps the structure from breaking down. The inner later keeps the window standing even though the glass shatters, much like a car windshield.
There are varying types of impact window glass available. Depending on where you live, housing code compliance may have different requirements, such as thickness and window design.
If you live in a hurricane region, you may want to consider impact windows to keep your home safe and remain housing code compliant.
