The Steel Window Institute (SWI) announced it reviewed and updated its steel windows and doors specifications and detention specifications. The specifications, which incorporate ASTM standards, have information to help define minimum performance requirements of steel windows and doors. To download the specification documents, visit

“The SWI specifications provide clear instructions in an easy-to-use format on the intent, performance, and construction of steel windows and doors,” said Ryan Carlson, chair of SWI’s Technical Committee. “They also provide reference to the quality and standards which should be applied to the material and product, assuring architects that the product they purchased is being delivered.”

The specifications are broken into five sections including hot rolled, cold rolled and fire rated. The detention specifications cover various types of security windows such as steel maximum/moderate and stainless-steel options.
With the materials and manufacturers’ products defined, the ASTM standards reference the performance for air infiltration, water penetration, and, in the case of non-weather strip sections, structural requirements that steel windows and doors must meet or exceed. The specifications also include sections on product inspection, installation and cleaning.
