There are several different types of wall insulation, including:
1. Fiberglass insulation - made of tiny glass fibers and is one of the most common types of insulation for walls.
2. Cellulose insulation - made from recycled paper products and is blown into the wall cavities.
3. Spray foam insulation - made of polyurethane and is sprayed into the walls. It expands to fill the cavity and creates a barrier against air and moisture.
4. Mineral wool insulation - made from rock or slag and is a good option for fire resistance.
5. Radiant barrier insulation - reflects heat and is best used in hotter climates.
6. Insulated concrete forms (ICFs) - made of reinforced concrete and insulating foam and provide excellent insulation for walls.
7. Rigid foam insulation - made of polystyrene, polyisocyanurate, or polyurethane and is often used in exterior walls or as a continuous insulation system.
