Gypsum industry news
US: CertainTeed has gained six additional Environmental Product Declarations (EPD), bringing its total number of gypsum wallboard EPDs to 12. The building materials producer started launching product specific EPDs in the drywall category in late 20115.
"CertainTeed is proud to have pioneered EPD verifications both within our drywall products and extending across CertainTeed insulation and ceilings categories. Since the beginning, we've delivered on our commitment to provide better product transparency so that our customers can make informed decisions on environmental sustainability implications at the initial stages of project development," said Dave Engelhardt, president of CertainTeed Gypsum.
CertainTeed Gypsum offers 12 product-specific Type III EPDs that include seven plants in four different product categories. The company says it is the only manufacturer to offer 'Cradle-to-Grave' EPD transparency that takes the entire development process into account. The EPDs from CertainTeed Gypsum are third-party verified by UL Environment and include information on global warming potential, embodied energy and other impacts that occur as a result of manufacturing.
The six new EPDs are available for four product groups including AirRenew, M2Tech, Easi-Lite and CertainTeed Type X. AirRenew is produced at the Moundsville plant in West Virginia and the other products are manufactured at the Montreal plant in Quebec, Canada.
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.
UK: Saint-Gobain's British Gypsum is making it easier for specifiers and architects to identify environmental performance with the launch of seven new Environmental Product Declarations (EPD) that cover nine products.
As part of its aim to give environmental transparency and make it easier for specifiers to gather evidence for building certification schemes, such as BREEAM, LEED and SKA, British Gypsum has introduced additional EPD to its Thistle plaster range. These include declarations for Thistle BoardFinish, MultiFinish, BondingCoat, Browning, Universal OneCoat, DuraFinish, SprayFinish, ToughCoat and HardWall.
The EPDs were externally verified for the Thistle plaster products following a robust Life Cycle Assessment (LCA), which calculated the environmental impact of each product throughout its lifecycle. The LCA considers a range of factors, including the effect of raw materials, manufacturing process, installation, performance in use and recycling capabilities.
"As our EPDs are based on clearly-defined EU-wide rules and regulations, our customers can be confident in the knowledge that they are receiving reliable indicators, allowing them to make an informed decision when planning or delivering a project," said Heidi Barnard, sustainability leader at British Gypsum. "We're currently the only UK plaster manufacturer to offer EPDs, but we recognise the importance of giving our customers greater transparency, especially in our industry, where sustainable practices are becoming more rigorous on an almost daily basis."
