At AppleBlossom Energy, we have been the Charlotte, North Carolina area’s place to turn for insulation since 2006. Here are a few types of insulation we work with and how they differ from one another:
- Cellulose insulation—Cellulose insulation is made primarily out of paper, including cardboard, office paper, and recycled newspaper. Cellulose has the lowest level of embodied energy of common insulation materials. Even though many people who hear cellulose insulation is made out of paper might think it is highly flammable, it is actually treated with natural borates, which are a type of Class I fire retardant. The borates also serve as an insect and pest repellant.
- Fiberglass batt insulation—Fiberglass batt insulation is the most common type of insulation used today, and it comes in two main forms: blown-in loose fill and pre-cut batts. In most cases, fiberglass insulation is used in attics, wall cavities, and in other open spaces to reduce noise and achieve greater thermal comfort. Fiberglass insulation is made out of short, or discontinuous, glass fibers.
- Spray foam insulation—This type of insulation is made out of two composite materials: isocyanate and polyurethane. When these materials are combined, a chemical reaction occurs that forces them to expand and harden. When spray foam insulation is applied, both the isocyanate and the polyurethane are released from the tip of a spray foam gun, which allows a protective layer of insulation to be precisely placed over the desired area.
