Window frames are one component of a window assembly. In naturally ventilated buildings window frames allow the window to be opened to bring in fresh air and closed tight to prevent intrusion. Steel frames were popular in the early to mid 1900's, but they are not typically used in this day and age because they are heavy and rust easily. Sometimes steel is specified where fire-protection and extra-strength assemblies are required by code.
