US: Carbon monoxide (CO) from external sources can easily penetrate gypsum wallboard according to a study published in the Journal of the American Medical Association by Neil B Hampson, James R Holm and Todd G Courtney of the Virginia Mason Centre for Hyperbaric Medicine. The study is believed to be the first to examine the ability of CO to diffuse through gypsum wallboard.

In the study, a plexiglas chamber divided by various configurations of gypsum wallboard was used to determine whether CO diffuses across wallboard. Wallboard of various thicknesses were used. CO test gas was infused into the chamber and then CO concentrations were measured once per minute in each chamber for 24 hours. The authors sought to determine how rapidly a concentration of CO toxic to humans would be reached in the non-infused chamber and whether diffusion would then continue. The researchers found that CO diffused across single-layer gypsum wallboard of two thicknesses, double-layer wallboard and painted double-layer wallboard.

"Gypsum's permeability to CO is due to its porosity. The ability of CO to diffuse across gypsum wallboard may explain at least some instances of CO poisoning in contiguous residences. Exempting residences without internal CO sources from the legislation mandating CO alarms may put people in multifamily dwellings at risk for unintentional CO poisoning," said the study. Carbon monoxide poisoning causes about 500 accidental deaths annually in the US.

US: The Gypsum Association has released GA-227-13, 'Recommendations for the Prevention of Ceiling Cracking', a publication outlining methods to mitigate cracking in large-span wallboard ceilings due to fluctuations in temperature and humidity.

GA-227-13 explains that ceiling cracks can appear at gypsum board joints when the span between framing members approaches or exceeds 4.5m. The centreline cracks can occur because materials such as gypsum wallboard and wood framing shrink and expand at different rates due to periodical changes in moisture content and temperature. To address the issue, the document details how resilient channels can reduce the occurrence of cracking.

"The methods for the use of resilient channels described in this document have been shown to be very effective in preventing ceiling cracks due to swings in temperature and moisture content of wood framing - particularly in long spans," said Robert Wessel senior director of technical services for the Gypsum Association. "The swings usually occur during a change in season from summer to winter or in dry areas such as desert environments."
