Quality thermal insulation is designed to improve temperature regulation through installation in walls, floors, ceilings, roofs and other spaces. Without it, the increased demand to heat or cool buildings raises energy consumption, associated costs, and CO2 emissions.

ROCKWOOL solutions are designed to help maintain a steady indoor temperature. Our stone wool products lead to more energy efficient constructions and renovations. Indeed, properly installed insulation can act to reduce energy consumption by up to 70 percent1.

When fitted, stone wool insulation can create a comfortable living or working environment for those inside buildings, as well as lowering energy bills – contributing to a more sustainable way of living.

Our thermal insulation solutions can be installed in a wide variety of building applications. This includes external walls and roofs, as well as ground and separating floors.

As an added benefit, stone wool insulation also provides acoustic protection, and enhances the fire resilience of buildings.
