Thermal insulation

Die Annotation des Normtextes ASTM C1497-24 :

This specification covers the composition and physical properties of spray-applied cellulosic fiber stabilized thermal insulation applied to open or closed ceiling spaces, regardless of slope. The basic material shall be recycled cellulosic fiber made from selected paper or paperboard stock. Stabilized cellulosic fiber thermal insulation is produced by the addition of adhesive(s) to loose-fill cellulosic fiber insulation. Additives are introduced to provide properties such as flame resistance, processing and handling characteristics. An adhesive is added to the insulation product to resist long-term settling of the insulation after installation and curing. Different test methods shall be performed in order to determine the following properties of thermal insulation: density, corrosiveness, critical radiant flux, fungi resistance, water vapor sorption, odor emission, smoldering combustion, thermal resistance, flame resistance permanency, shrinkage, and settling.
