US: The Gypsum Association (GA), which represents the North American manufacturers of gypsum wallboard, has released an industry-wide environmental product declaration (EPD) for glass mat gypsum panels. The EPD provides environmental performance information addressing energy consumption, water consumption, global warming, waste, air emissions and other metrics related to production.
"The development and release of this ISO 14025 conformance, Type III, cradle-to-shipping gate EPD, demonstrates that our member companies are committed to transparency as a means of improving the environment and increasing the sustainability of building products," said Stephen Meima, LEED Green Associate, executive director of the Gypsum Association.
The international standards organisation, ASTM, served as program operator for the EPD. The GA commissioned the Athena Sustainable Materials Institute (ASMI) to perform the Life Cycle Assessment (LCA) that informs the EPD and to produce the EPD Project Report.
Glass mat gypsum panels are specialised performance products consisting of a no-combustible moisture resistant core encased in fibreglass facers on front and back surfaces and long edges. Also known as 'exterior gypsum sheathing,' this product provides extended weather protection, mould and moisture resistance, and fire resistance when specified as a component of a building's exterior envelope. Glass mat gypsum panels are compatible with a wide variety of exterior claddings including wood, masonry, metal, vinyl and stucco. Glass mat panels are increasingly used in the rapidly expanding multifamily residential sector.
