Inside ASTM’s Window Testing Protocol

ASTM stands for the American Society for Testing and Materials. Despite the name, ASTM operates internationally with offices in the United States, Europe, Asia, and South America. The organization develops and publishes technical standards for a range of industries, from aeronautics to healthcare. One of the earliest industries ASTM developed standards for was the construction sector. At Renewal by Andersen, we rigorously apply ASTM’s window testing standards and meet or exceed industry standards for all of our products.

ASTM’s Window Testing Protocol

ASTM has developed a number of window testing protocols to ensure that windows are up to industry standards. These include tests to determine the force needed to open and close different window styles, tests for water and air infiltration, and tests to determine the breakaway force. These and other tests are performed under controlled conditions in a laboratory following the same instructions used by our certified master installers.

Our Test Results

We are committed to excellence in craftsmanship, a promise we make that lasts well past the installation of our windows in your home. For example, we continue to field test based on ASTM’s E2068 protocol for determining operating force. Even after 20 years of regular use, our double hung windows perform great. Because we manufacture our own windows using our revolutionary Fibrex material, customers can rest assured that both the manufacture and installation were done by a company with over a century of experience exceeding industry standards. 

Thanks to ASTM’s window testing protocols, manufacturers can discern performance baselines. Customers know they’re purchasing a product that has been specifically manufactured to meet or exceed industry standards.
