THV Compozit Thermal Line Window Systems THV Compozit Window Systems FrameTHV Compozit Window Systems meet or exceed AAMA performance standards in all areas.The American Architectural Manufacturers Association is a collection of scientific, production, and business people whose primary goal is to promote quality, confidence and knowledge throughout the construction industry. It issues standards for a variety of products and materials and performs quality audits of manufacturers to ensure standards are met . The AAMA has set rigorous standards for product certification in four areas:Dimensional StabilityMeasures the ability of a window part to maintain its shape over changing temperature ranges. When temperatures exceed the part's strength, a one time shrinkage can occur, affecting the operating performance of a window. Impact ResistanceRefers to how well a product can resist damage such as cracking or breaking during shipping, storage and installation. WeatherabilityThere are two aspects of weatherability. The first regards color and how well a material can hold its initial color and not fade over time. The second, impact retention relates to a material's ability to withstand environmental and temperature extremes over time. Heat ResistanceTests the materials ability to withstand extreme heat without blistering, cracking or delamination. |
