Insulation can help to increase overall energy efficiency, improve occupant comfort, manage risks of mold and mildew, and even minimize the spread of fire. When designing exterior wall assemblies, the type and placement of insulation is critical. To address thermal performance, wall systems almost always feature insulation – once predominantly in the form of batts friction fit between framing members. However, batts alone have been demonstrated not to provide enough thermal resistivity for the wall.

Continuous insulation in conjunction with batt insulation in the stud cavity is now a building code requirement across the country to optimize thermal performance. Mineral wool continuous insulation is an inorganic, noncombustible solution to building energy efficient wall assemblies that protect occupants from exterior temperatures, moisture, noise, and even fire.
