Igloo Cellulose Insulation acts as an effective protective shield to reduce the transmission of heat or sound. Made from 85% recycled newspaper and biodegradable protective additives cellulose consists of loose small gray wood fiber texture smooth to the touch. Usually blown or spray applied, blown cellulose insulation easily fits in difficult to reach tiny spaces in attics, floors and walls to seal tight. It acts like a non-conductor of heat and sound waves. Efficient and very environmental-friendly, Cellulose will reduce energy consumption and generally improve interior comfort for a wide range of climatic conditions in residential and commercial applications.
