Thermal Insulation controls the movement of hot and cold air between spaces, whether between the inside and outside of a building, or between rooms or levels inside. There are many insulation products with diverse characteristics available depending on specific project needs. The following sections give overviews of the most common insulation types and their applications.

While insulation is most commonly thought of as a thermal barrier for use in exterior walls , interior spaces can also benefit from insulation's sound control properties. The correct products can greatly reduce noise between adjacent rooms and levels, increasing building occupant comfort and productivity. The pages under the heading
