High Impact Windows

High Impact Windows from TISW Corp. are precision-engineered to withstand hurricane-force winds and are thoroughly tested to ensure compliance with the strict building codes in coastal areas. The windows are tested by the American Architectural Manufacturers Association (AAMA) at their independent, accredited laboratories. Our windows are subjected to high velocity winds and rigorous water resistance testing to make sure the windows meet our high quality standards. All windows are tested to ASTM E547 for water resistance and to ASTM E238 for air infiltration, and must meet or exceed these performance standards.
