If you are looking for “green” insulation materials, cellulose is for you. Not only is it lower in cost but it is as efficient if not more than other, mineral or chemical insulation materials. The cellulose fibers are better at covering holes and gaps than other mineral materials as to the better consistency. Cellulose is also an irreplaceable sound insulator.
Cellulose is made by naturally recycling wood fibers such as newspapers so in addition to saving energy at home by insulating your walls and ceilings with cellulose you will also contribute to saving energy in a more global sense and help solve rapidly growing waste problems. Installing cellulose insulation will also save you a considerable amount of money compared to other insulation materials.
Another advantage of cellulose insulation is that it is specially treated to be more fire-resistant than other mineral insulation materials so using cellulose insulation will make the house a safer place for your family. Also it is proved to not advance the growth of mould.
As cellulose is mostly installed by blowing it into the walls you will also need special equipment for that like a cellulose insulation blower and preferably a professional to help you with the installation.
