Postcard #1: Architectural glass products must be properly cleaned during construction activities and as a part of routine maintenance in order to maintain visual and aesthetic clarity. Since glass products can be permanently damaged if improperly cleaned, glass producers and fabricators recommend strict compliance with the suggested procedures outlined in this postcard for properly cleaning glass surfaces.

Postcard #2: During glass manufacturing, fabrication and installation, products are carefully handled to prevent surface and edge damage. Materials are packaged to provide protection during shipment and delivery. Once finished materials are placed on a construction site, they become exposed to a variety of conditions and influences that can adversely affect product aesthetics and functionality. Irreparable glass damage can occur from improper storage and handling, exposure to chemicals and leaching agents, prolonged exposure to moisture, mechanical attack and breakage, damage related to adjacent construction activities and improper cleaning methods. This postcard discusses the steps that should be taken to avoid permanent damage to glass.

This package of two postcards provides information derived from two of NGA’s Glass Technical Papers: FB01-00 Proper Procedures for Cleaning Architectural Glass Products and FB03-03 Construction Site Protection and Maintenance of Architectural Glass.

The Technical Services Division of the National Glass Association (NGA) has produced these postcards solely for informational purposes. These postcards were developed by dedicated member volunteers and subject matter experts. This is the original version of this product. It was approved and published in February 2024.
