What are impact windows?

Definition

Impact windows, also known as hurricane windows or storm windows, are specially designed windows that are built to withstand the impact of high-speed winds, flying debris, and extreme weather conditions, such as hurricanes and tropical storms. These windows are made of strong and durable materials that are capable of resisting the force of strong winds and protecting the interior of a building from damage.

Features

The key feature of impact windows is their ability to resist the impact of flying debris. This is achieved through the use of laminated or tempered glass and reinforced frames. The glass used in impact windows is made up of multiple layers of glass and a special interlayer, typically made of ethylene-vinyl acetate (EVA) or polyvinyl butyral (PVB), which holds the glass together even when it is shattered. The frames of impact windows are usually made of aluminum, vinyl, or fiberglass, which are strong and resistant to corrosion.

Materials

There are various materials used in the construction of impact windows, including glass and frames. The glass used in impact windows is typically laminated or tempered glass. Laminated glass consists of two or more layers of glass with a layer of plastic interlayer sandwiched between them. This interlayer helps hold the glass together when it shatters, providing additional strength and safety. Tempered glass, on the other hand, is heat-treated to increase its strength and durability. The frames of impact windows are commonly made of aluminum, vinyl, or fiberglass, all of which are known for their strength and resistance to weathering.
