Cellulose insulation

The word cellulose comes from the French word cellule, for a living cell, and glucose, which is sugar. Building insulation is low-thermal-conductivity material used to reduce building heat loss and gain, and reduce noise transmission. Cellulose insulation is plant fiber used in wall and roof cavities to insulate, draught proof and reduce free noise.

Cellulose insulation is plant fiber used in wall and roof cavities to insulate, draught proof and reduce free noise. Cellulose is among the oldest types of building insulation material. Many types of cellulosic materials have been used, including newspaper, cardboard, cotton, straw, sawdust, hemp and corncob. Monticello was insulated with a form of cellulose. Modern cellulose insulation, made with recycled newspaper using grinding and dust removing machines and adding a fire retardant, began in the 1950s and came into general use in the US during the 1970s
