Global Window Films and Paint Protection Films are manufactured by Garware Hi-Tech Films Limited, which traces its roots back to 1933 as a trader of imported vehicles. In 1981, Garware shifted its focus to polyester film manufacturing, including automotive and architectural window films as well as paint protection film. Garware has the unique distinction of being one of only a handful of film manufacturers that is vertically integrated thanks to its ability to extrude its own polyester. That means Garware can maintain control of all raw ingredients to ensure the highest quality possible.
