NGA: “Decorative Glass GTP” and “Thermal Bridging Design Guide”

Available for immediate download from the online NGA store

NGA has published two new resources – Types of Decorative Glass Glass Technical Paper (GTP) and Thermal Bridging Considerations at Interface Conditions Design Guide.

Task groups comprised of member volunteers within the Fabricating and Installing Committees worked to develop these brand-new resources that standardize industry jargon and set a knowledge base for conversations.

Types of Decorative Glass
The Types of Decorative Glass GTP defines the most common methods of decorating glass in the industry today. Given its versatile nature, decorative glass can be incorporated into a variety of design intents that can also achieve exceptional mechanical and chemical durability, not to mention its ability to capture, reflect, absorb and manipulate light.

“This five-page resource is a glossary of terms to aid in selecting and specifying decorative glass into a project,” said Urmilla Sowell, NGA technical and advocacy director. “It will help you understand the types of decorative glass, edge and surface treatments, and films and coatings.”

Thermal Bridging Considerations at Interface Conditions
The Thermal Bridging Considerations at Interface Conditions Design Guide discusses thermal bridging as it pertains to the thermal performance of fenestration systems and their interface with the surrounding conditions. Attention to these details can affect the overall thermal performance of a building envelope but are often not part of the glazing subcontractor’s scope of work.

“Getting the glass, the thermal barrier in any glazing system, aligned with the insulation material or layers in the adjacent construction to improve overall building envelope performance is what NGA’s Thermal Bridging task group sought to address,” said Chuck Knickerbocker, task group chair, Technical Glass Products. “We recognize this is going to require a refocus from the design community, general contractors, installing trades and suppliers alike. Like other challenges related to the thermal performance of the building envelope, it’s one we as a design and construction industry ought to take on, and this paper starts to lay out how we in the glazing trade envision this process evolving.”

Visit the NGA Store to purchase and download the Types of Decorative Glass GTP, available for free for NGA members and USD 4.95 for non-members, and the Thermal Bridging Considerations at Interface Conditions Design Guide, available for USD 24.95 for NGA members and USD 49.95 for non-members.
