US: A study conducted by researchers at the Massachusetts Institute of Technology (MIT) has found that spray foam insulation applied to walls prior to the entry into effect of the Montréal Protocol banning chloroflourocarbons CFCs) is acting as a ‘CFC bank’ from which environmentally degrading chemicals continue to leach into the atmosphere.

MIT Lee and Geraldine Martin Professor of Environmental Studies Susan Soloman recommended that all such banks be ‘recovered and destroyed.’ “Before demolishing a building, you can take careful measures to recover the insulation foam and bury it in a landfill,” she said.

US: National Gypsum Company has published SoundBook 2.0, an updated version of its manual for technical information and architectural drawings of sound-rated assemblies for architects and contractors seeking to achieve required sound transmission class (STC) ratings on their projects. The publication includes details and drawings of 310 sound-rated assemblies for steel and wood stud construction, as well as for floor-ceiling applications. The book also features acoustical terms, concepts and proper installation methods for optimal sound control. The original SoundBook was published in 2015.

“Acoustical performance is one of the most popular topics covered by our Construction Services Team,” said John Bianchi, gypsum product manager for National Gypsum. National Gypsum’s goal in publishing SoundBook 2.0 is to provide architects, contractors and others involved in specifying products current information and illustrations on sound-rated wall, ceiling and floor assemblies.

National Gypsum has released several new acoustical gypsum products as part of the company’s SoundBreak XP family of products since the initial rollout of its SoundBreak XP Wall Board, including SoundBreak XP Retrofit Board, designed for use as an extra noise reducing layer over existing wallboard, and its most recent innovation, SoundBreak XP Ceiling Board, a board for floor-ceiling applications.
