Impact Glass Windows

Impact Glass Windows

Unlike traditional windows that are constructed with normal glass, impact glass windows are made with impact-resistant glass. The best thing about this glass is that it is treated with ethylene-vinyl acetate (EVA) or polyvinyl butyral (PVB) layer. Here it’s important to state that impact-resistant glass will possibly smash by a strong impact if hit by flying objects. However, the broken glass will remain attached to its window frame and inner membrane. If a high-speed storm hits the impact glass window, it cracks in a spider-web pattern instead of sending out shattered glass pieces.

Some people install ordinary windows in their home and later add an extra layer of hurricane shutter or storm panel. But they fail to protect their windows from breakage as ordinary windows cannot provide the same protection level as that of impact glass windows. It must be kept in mind that genuine impact-resistant windows are costly, but they are a good investment if you are living in an area that is prone to strong winds.

The frame of hurricane-resistant windows can use steel, aluminum, wood, or vinyl. Steel or aluminum frames are the strongest and costly, and also require some maintenance. Wood frames provide good insulation but they require regular painting that ultimately increases maintenance cost. Furthermore, wood-framed windows become vulnerable to warping with time. Vinyl frames are an economical option and offer good insulation value but their materials are difficult to recycle.

Different glass options are available for Impact Glass Windows and you can identify different types of glazing methods that are used to join glass panes with the inner layer.

 

  • Most of the impact-resistant windows contain a film of EVA or PVB, which is inserted between two glass panes. EVA or PVB layer has great shock-absorbing properties. The thickness of EVA or PVB film usually ranges between 0.015 and 0.090 inches. The increase in thickness will both increase the strength and the price of impact glass windows.

 

  • In some impact-resistant windows, a layer of polyethylene terephthalate (PET) is combined with PVB to provide a strong glazing option. However, their price is very costly due to the complex manufacturing process. These windows contain a PET film that is sandwiched between two PVB-treated glass layers.

 

  • SentryGlas Plus (SGP) is another option. In this technology, an inner layer of proprietary inoplast material is sandwiched between two glass layers. SGP is stronger, lightweight, and less prone to yellowing. The layer of SGP is approximately 0.90 inches thick. These types of windows are commonly used for commercial buildings. However, they can also be installed in a residential property. These windows are the most expensive impact glass windows.

 

  • Glass can also be treated with liquid glass resins by a procedure that utilizes ultraviolet light to cure and congeal it. In some windows, a polyethylene terephthalate layer is also enclosed to enhance the strength of glass. These types of windows are quite famous in Florida.
