Impact-resistant glass is the last type of protection for windows and doors of steel buildings. This practically eliminates the need for hurricane shutters. Installing impact-resistant glass is actually more expensive especially for old steel buildings.

The idea of using shatter-resistant glass for windows and doors of buildings and residences was inspired by the use of laminated glass by the automotive industry. Impact-resistant glass doors and windows offer permanent protection from storms. However, they must be installed by professionals.

There are two common types of impact-resistant glass for windows and doors. The first kind is laminated glass consisting of a shatter-proof membrane sandwiched between two sheets of glass. Upon impact, the glass may shatter but not scatter. The inner membrane will hold the two sheets of glass firmly together. Thus, the barrier is not broken.

Laminated glass windows and doors are designed to handle wind-borne debris and repeated impact from unwanted intruders. The thickness of the interior lamination ranges from .015 inch to .090 inch. The inner film even comes in a variety of color tints to choose from.

The second type of impact-resistant glass for steel buildings uses shatter-resistant film placed over the glass to keep the shards in place if broken. Since these films are just applied to the glazing, they may not function as a complete system and may not offer the protection required.

Impact-resistant glass installed in steel buildings, not only provide safety and protection from damages caused by storms but also security from intruders. In addition, it also offers increased sound and sunlight control. The strength and quality of the glass actually reduces the amount of exterior noise and ultraviolet rays of the sun, which can make their way into the building. The color tint also helps to reduce or eliminate sun fade and ultraviolet damage for interiors of steel buildings.
