Emissions from thermal insulations—part 2: evaluation of emissions from organic and inorganic insulations

Influence of eco-materials on indoor air quality

“…9 VOCs found in an indoor environment can originate from a wide range of sources such as outdoor (traffic, industries), human activities (cleaning, cooking), furniture and building materials. 4,[10][11][12] Emissions from building materials are classified as primary or secondary. Primary emissions include the physical release of non-bound VOCs, which are present in a new product (e.g.…”

Microbial quality of linseed and fibre hemp plants during growing and harvest seasons

“…for thermal insulations. During the growing season of 2001 the mould content in fi bre plants analyzed was higher than this limit value, but during the manufacturing of the insulators the raw materials will be heated and fi nished insulators contain various anti-mould agents, which reduce their tendency to mouldiness (Koivula et al 2005). Further research is needed to provide more information on the distribution of the microbes in different parts of the plant and in the separated fractions.…”

“…In a study of Kymäläinen et al (unpublished results), mechanically separated fi bre contained less microbes than the dried stalk. The microbiological quality of hemp and linseed insulation materials is published in a separate investigation (Koivula et al 2005). The present study provides a basic understanding of the microbial quality of stems during the growing and harvest seasons.…”

Antimicrobial natural fibres

“…Airborne microorganisms are very hazardous, especially in post-operative infections (Kolmos et al ., 1997). Bedmaking generates dust and airborne microorganisms (Shiomori et al ., 2002), and microbes are emitted from thermal insulation as well (Koivula et al ., 2005).…”
