Polycarbonate Security Glass
Polycarbonate security glass is optimal for exterior windows because of its resistance to forced entry. However, it has poor light transmission. A sheet of polycarbonate will withstand repeated strikes from a sledgehammer where its acrylic counterpart cannot. Polycarbonate can be coated with an abrasion resistant layer which affords it increased protection from solvents, weather, and UV light.
Level 1 polycarbonate security glass is able to withstand shots from small caliber handguns, most commonly used in armed robberies. Most small businesses use Level 1 bullet resistant glazing as a crime deterrent. This material is commonly found in places like Gas Stations, Retail Stores and Pharmacies.
Level 2 security glass is able to withstand shots from larger caliber handguns, and is made for buildings with increased security concerns. Businesses that use Level 2 bullet resistant acrylic include Banks, Financial Institutions and other businesses with increased security concerns.
Level 3 security glass is able to withstand shots from larger caliber handguns like a .44 Magnum and is recommend for larger buildings that have a higher threat level and a greater number of employees or occupants. This level is suitable for environments where threats are potentially more severe and there is a greater level of occupant endangerment, including schools, police stations and government facilities.
