Spray In Cellulose
A low moisture wet product manufactured from recycled wood products (such as newspaper) that is sprayed on. Once dry, it is shaved off for a clean and smooth application. It can be used for attics, new or existing wall cavities, or sprayed over old insulation.
It is also fire and mold resistant. Like any insulation installed it will save you up to 20-50 percent on your energy bill.
