Section 8520 Secondary Glazing

In reality, the Construction Specifications Institute (C.S.I.) format does not deal effectively with the various types of secondary glazing systems (commercial storm windows). As a result, many product directories and even architects have found it necessary to create their own specification number for the storm windows that they seek to identify. They are always in the 08500 Series (windows), – but the consistency stops there. They are sometimes placed under “Special Function Windows”. There is a variety of specification numbers for “Interior Storm Windows”. No category for “Exterior Storm Windows’ has been clearly identified.

We recommend that architects and specification writers make use of the various tools that are available on this web site:
