Impact Glass Windows

Impact Glass Windows

Windows that are categorized as storm-proof or hurricane-resistant are manufactured with impact-resistant glass, which is treated with PVB (polyvinyl butyral) or EVA (ethylene-vinyl acetate). This impact glass is capable of remaining stick to the window frame if a high-speed wind or hurricane hits it. In this way, whenever a storm or hurricane hits the impact glass windows, the inner impact glass breaks and crack windows in a spider-web, fine pattern instead of scattering out the glass pieces. So, the homeowners can protect their family and belongings from a huge monetary or physical damage.

Unlike the ordinary windows, impact glass windows are a bit expensive but it is worth using them because of several benefits. An impact-resistant window can use steel, aluminum, wood, or vinyl for the frame. Steel or aluminum frames are among the strongest ones, but they also require maintenance for long term usage. Vinyl frames are an affordable solution and have a good insulation value, but their recycling can be tough. Lastly, wood frames also have good insulation value, but they must be painted regularly that ultimately increases the maintenance cost. Also, wood-framed windows become prone to warping over time.

Several options are available for impact glass windows and you can find different glazing types. Manufacturers can use different glazing types to join interlayer with glass panes.

  • A film of EVA or PVB incorporated between 2 glass layers is the commonly used type of impact glass windows. EVA or PVB is capable of absorbing impact upon struck. These two types of films have a different thickness that ranges from 0.015 to 0.090 inches. The more the thickness of the film, the more will be the price as well as the strength.
  • Some manufacturers also use PET (polyethylene terephthalate) in combination with PVB to provide a strong glazing option. However, their manufacturing process is quite challenging that is why their price is costly. This type of window often consists of 2 layers of PVB with one film of PET in between them.
  • SGP (Sentry Glass Plus) technology is also used in the making of impact glass windows. In this technology, a middle layer of inoplast material is used between the panes of glass. SGP is light in weight but stronger and less prone to yellowing with time as compared to other hurricane-resistant windows. These windows are mostly used for commercial purpose, but can also be ordered for home or apartments.
  • Liquid glass resins are sometimes applied permanently to glass by a procedure that utilizes UV light as the catalyst to harden and cure it. Liquid glass resins windows are quite famous in Florida.
  • Plastic/glass hybrid windows incorporate a thin film of polycarbonate Lexan between 2 glass panes and fasten the materials together. It provides a stronger glass, but it is not suitable for warm climates as polycarbonate expands more as compared to glass.
