Construction Site Protection and Maintenance of Architectural Glass (GANA TD 03-1003)
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 document discusses why steps must be taken to avoid permanent damage to glass.

Glass for Personal Protective Barriers (NGA with GANA FB65-20)
Many businesses are installing clear personal protective barriers to physically shield employees from each other and from consumers to reduce potential exposure to the coronavirus. In many applications, the barriers will become a permanent fixture; therefore, aesthetics and cleanability are important design considerations. Barriers can be constructed of plastic sheet or glass.Glass has several advantages in physical barrier applications and may be preferred over plastic, especially for permanent and public-facing barrier installations. Compared to plastic, glass is easy-to-clean, transparent and aesthetically-pleasing.

Guidelines for Handling and Cleaning Decorative Glass (GANA DD 01-0608)
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 guidelines within this document are intended to inform and assist those who fabricate, use and maintain decorative glass products.

Heat-Treated Glass Surfaces Are Different (GANA TD 02-0402)
As the use of glass increased over recent years, issues of strength, safety and thermal performance became increasingly important design considerations. The availability of tinted and coated glasses had a dramatic impact on glass use in building projects. The vastly expanded aesthetic options, combined with the improved energy conserving and comfort capabilities of tinted and coated glasses allowed architects to use more glass, as well as larger sizes in their designs. A consequence of this trend was a corresponding increase in the use of tempered and heat-strengthened glass in order to meet both thermal and windload design requirements. The demand for tempered glass further increased with the passing of safety glazing legislation in 1977, which mandated its use in certain locations. This document discusses why industry cleaning procedures must be followed to avoid glass damage.

Installation Techniques Designed to Prolong the Life of Flat Glass Mirrors (GANA MD 03-0709)
The reflective surface of a mirror is a thin film of pure metallic silver. Although well protected by paint, the silver film remains vulnerable to corrosion if exposed to chemicals or excessive moisture. This document provides some important installation recommendations. Strict adherence to these dos and don’ts will help protect the silver from corrosion and prolong the life of the mirror.

Laminated Glass Use in Furniture (NGA with GANA FB37-12)
Glass is often used to enhance the beauty and style of furniture. It allows lighting to penetrate into the opening, provide an enhanced view of displayed objects or as a protective layer on continuously backed surfaces such as tables or as the primary loading surface in horizontal applications. Typical applications include table tops and table bases, cabinetry, and shelving. Glass can break, even if it is rated as a safety glazing and care should be taken to minimize glass-related injuries. This document discusses terms and applications for using laminated glass in furniture. This document was published in July 2012, and updated in 2019.
