Environmental Information
Guardian works closely with the Lawrence Berkeley National Laboratory (LBNL) on the development of THERM – a state-of-the-art, Microsoft Windows-based computer program for use by building component manufacturers, engineers, educators, students, architects and others interested in heat transfer. Using THERM, users can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, doors, appliances and other products where thermal bridges are of concern. THERM's heat-transfer analysis allows you to evaluate a product’s energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity. THERM is a module of the WINDOW+5 program, which is the next generation of the WINDOW software series. THERM's results can be used with WINDOW's center-of-glass optical and thermal models to determine total window product U-factors and Solar Heat Gain Coefficients. These values can be used, in turn, with the RESFEN program, which calculates total annual energy requirements in typical residences throughout the United States.

All Guardian Automotive plants comply with the End-of-Life Vehicle Directive. This includes identifying and reporting restricted and reportable substances found in the materials used for Guardian vehicle components. This information, entered into the International Material Data System (IMDS), will be used at end-of-vehicle life for recycling purposes. Additionally, end-of-vehicle life efforts have led to the reduction and/or elimination of hazardous substances such as lead, mercury, cadmium and hexavalent chromium in Guardian’s automotive components. Currently, 16 international automobile manufacturers use the information found in the IMDS database.
