Airtight Services uses a variety of insulation products to air seal and insulate your home.
Cellulose
Treated with only boric acid and has passed all fire code requirements. Many other cellulose products readily available are treated with sulfates and borates. Sulfates can be corrosive, and in older homes cause electrical problems with BX wire.
