Parameters influencing the emissions of volatile organic compounds from OSB
Several international initiatives have been launched in order to evaluate and reduce VOC emissions from building products. The measurement is usually carried out by sampling of test chamber air. Organic emissions of oriented strand boards (OSB) made of Pinus sylvestris L. are composed of terpenes and aldehydes. Autoxidation of unsaturated lipids inside the wood form the latter. - Process parameters such as surface structure and panel thickness have great impact on the initial emission level as well as on the development of emissions over time. Especially, the characteristics of aldehyde emissions are affected, whereas the effect on long term emissions is Limited. A major factor on the level and composition of emissions is the wood species employed.
