Cellulose is among the oldest types of building insulation material used. We have always needed to keep cool in hot conditions and warm in cool conditions. Many types of cellulosic materials have been used, including newspaper, cardboard, cotton, straw, sawdust, hemp and corncob. Modern cellulose insulation is made with recycled newspaper, which has a very high content of cellulose present in the paper, using grinding and dust removing machines and adding a fire retardant, began in the late 1940s and is today widely in use worldwide.. Mainly used for Ceiling Insulation..
Every time there is an energy crisis, people move from a wasteful lifestyle to one of conservation. With the energy crisis in South Africa, the government moved to make ceiling insulation compulsory in all new buildings in South Africa. SANS 10400 XA was published in 2011 and "Energy Efficient Buildings" and the technology behind it has become the buzz word.
Cellulose insulation is produced locally by manufacturers who operate state of the art manufacturing facilities and offer an environmental alternative to other more expensive products with a high embodied energy. Ceiling Insulation in South Africa is regulated through the national building regulations and must perform to certain standards to be accepted. Quality includes fire resistant standards, R-Value of the product and various other performance qualities and is being promoted by TIASA (Thermal Insulation Association of South Africa) in association with the SABS and other governing bodies.
Too many manufacturers made outlandish claims about the performance of their insulation and the "R-value Rule," was established placing clear limitations on the claims that manufacturers and marketing companies can make about their product. The effect of regulations has put most of the fly by night producers of cellulose insulation out of business and has left the market with only reputable manufacturers and has assured a quality product to the end user.
Currently cellulose insulation has increased steadily in popularity worldwide. Part of the reason for this popularity are studies that suggest that cellulose may actually protect a building from damage in a fire better than fiberglass because cellulose is denser than fiberglass and doesn't allow the oxygen necessary to burn structural members. Several National Research Council Canada studies have backed these claims. Another major reason for the popularity of cellulose might be because of the increased interest in green building. Cellulose has the highest recycled content of any insulation material and also has less embodied energy than fiberglass and other furnace produced mineral insulations.
