Unhealthy indoor air usually results from chemical or biological emissions from the construction materials of a building. The result is building related illnesses (BRI) with symptoms such as asthma, skin and eye irritation, fatigue etc. A new generation of chemical-free emissions barriers has been developed and proven to be successful in stopping emissions such as mold products, aldehydes, alcohols, chlorophenols, chloroanisoles, PAH, odorous and non-odorous VOC etc, without affecting the building structure. Indoor surfaces from where the emissions are being spread (floor, ceiling, walls) are covered with the barrier and the emissions are thus prevented from reaching the indoor air. We will describe how a surface emissions trap (cTrap), an adsorption cloth developed from research at Lund University, can be applied in unhealthy buildings. The result is an immediate disappearance of measurable and perceived emissions including any odor. In summary, an emissions barrier may offer an efficient, economic, quick, and environment-friendly way of ensuring a healthy indoor air and avoiding BRI.
ABOUT THE PRESENTERS:
Lennart Larsson holds a PhD in analytical chemistry and is currently professor emeritus in microbial metabolomics at Lund University, Sweden. During the past 25 years his research has focused on indoor air quality especially in relation to building dampness, and in 2010 he launched a new product, the surface emissions trap (cTrap), developed to control spread of harmful microbial and chemical emissions from building materials into the indoor air.
Johan Mattsson holds an MSc in economics and has worked with business development e.g. at Lund University Sweden. He is CEO of cTrap Ltd, the cTrap being a unique emissions barrier currently used in restoration of buildings in several countries in Europe. See www.ctrap.com
