Decorative glass products have become important components of the architectural landscape. They contribute to the architecture and design requirements of interior and exterior applications for residential, commercial and industrial projects. In order to preserve the quality and integrity of decorative glass products and to ensure their long-term performance, fabricators, glazing contractors, related sub-contractors (e.g. millwork contractors) and building owners should follow appropriate procedures during handling, fabrication, installation, and cleaning. The Technical Services Division of the National Glass Association (NGA) has produced this Glass Technical Paper solely for informational purposes. This Paper was developed by dedicated member volunteers and subject matter experts. The original version of this document was published in 2008.
