Commercial Window Shield [CWS] is a South Carolina-based security and solar control window film installation company. The company started in the 1980s during the energy crisis installing solar control films on large office buildings.
After the Oklahoma City federal building bombing in 1995, in which hundreds were killed or injured by flying glass, film manufacturers developed a security film that kept windows exposed to bombs and foul-weather events from shattering. CWS became a significant company in this field, winning contracts to install security film on the U.S. Capitol, FBI headquarters, the Pentagon, all House of Representative and Library of Congress buildings, Grand Central Terminal and O’Hare International Airport.
More recently, CWS has added schools, airports and convention centers as security film installation clients and has also moved into the decorative and smart film installation business.
