Impact windows are a common type of window that helps prevent bullets from penetrating your home or building. They’re also considered hurricane proof, which means that they can withstand hurricane winds. Many people who have impact windows in their homes are aware of how well they work. You can choose from various types, such as tempered glass and laminated glass. The thickness of the glass also affects how well it protects you.
Some people refer to bullet resistant glazing as bulletproof, but this is a misnomer. Bulletproof glass is actually quite different from the more common impact windows. While they both have layers of security glass, the latter has a thicker inner layer. This extra thickness provides more protection. A thicker layer means that it can withstand more impacts, which may prevent bullet penetration.
Can Impact Windows Stop a Bullet?
Impact resistant windows are built from two separate sheets of glass, which are then joined together by a thin film of resin. Although this thin layer doesn’t stop bullets, it does stop them from shattering. For this reason, many bulletproof windows are made of laminated glass Fort Myers impact windows and doors. These materials are more durable than tempered or annealed glass, which are both very brittle and have a low resistance to impacts.
There are two types of bulletproof glass: laminated and acrylic. Acrylic is typically a solid plastic, but it can be drilled or slotted for routing. It’s a little less expensive than bullet-resistant glazing, but it doesn’t do as much. Another advantage of acrylic is that it has good visibility. If you’re looking to build an impact-resistant system that’s both stable and secure, it’s worth it to invest in a heavier, more sturdier acrylic.
Typically, a laminated glass window can be made stronger by adding an additional layer of polycarbonate. Polycarbonate is a strong material that absorbs and deflects impact. However, it can be penetrated by bullets. That’s why bulletproof windows have a thicker inner layer. One of the advantages of using polycarbonate is that it’s 80% lighter than glass.
Depending on the type of gun and the size of the bullet, the impact window will have different levels of resistance. Generally, you’ll be able to stop a single bullet from a small-bore rifle, but a large-bore rifle like the M16 could easily pass through the thicker inner layer. When a bullet is fired from the outside of a car, it will strike the brittle side of the material first, but it would be able to pierce the flexible material, which will absorb the remaining energy.
A laminated glass window can be very expensive, but it’s a good option for people who want to keep their costs down. An experienced fabricator can make a quality system with laminated glass. Most impact windows are treated with polyvinyl butyral or ethylene-vinyl acetate to prevent shattering. In addition to this treatment, many impact windows also have a PET window-glaze layer that helps to protect against rays.
Some types of impact windows have been tested to withstand Category 5 Hurricanes. During tests, they were placed in extreme conditions and then shot directly at them. Each type of impact window was tested to determine its effectiveness against various projectiles. Testing is done to ensure the safety of customers.
