Abstract
This article deals with thermal degradation of cellulose insulation. The sample of commercially available loose-fill cellulose insulation was tested in electrically heated hot air furnace modified for thermogravimetric analysis. Weight loss, weight loss rate and CO/CO2 ratio was measured, while the sample was heated from room temperature to 530°C. Particular phases of the thermal degradation process of cellulose insulation were identified and explained. The most rapid changes caused by thermal decomposition of loose-fill cellulose insulation were reported in temperature range 270°C – 380°C. The weight loss rate reached its maximum in 308°C, which was equal to 0,198g.min-1. Two temperature ranges in which the yield of CO was higher than the yield of CO2 were detected.
