Interior-insulated mass walls: the stone wool advantage
Mass walls provide thermal benefits through their mass, but modern energy codes require additional insulation to meet today's exterior wall performance targets.
Interior-insulated mass walls provide a strategic solution when you want to preserve a building's facade or face limited exterior wall access. This approach places continuous insulation on the interior side of concrete, brick, or CMU walls to enhance thermal performance while maintaining the exterior facade of heritage and historic buildings, and in new mass wall construction.
ROCKWOOL noncombustible stone wool insulation delivers multiple performance benefits in this application: exceptional thermal efficiency, superior moisture management, and fire resistance.
Stone wool insulation absorbs sound, maintains its R-value over time, and allows vapor movement in and out of the assembly. Made primarily from volcanic rock, stone wool supports sustainability goals through increased energy efficiency.
