Insulating a floor is necessary for many reasons, from improving energy efficiency to reducing unwanted noise levels.
Rockwool's RockFloor range has high compressive strength, absorbs sub-floor imperfections and is suitable for various installation methods. There are two RockFloor solutions: Thermal and Acoustic.
Thermal RockFloor achieves a thermal conductivity of 0.038 W/mK and minimises thermal bridging on ground floors. Acoustic RockFloor achieves a slightly higher thermal conductivity of 0.040 W/mK and reduces unwanted noise between intermediate and separating floors.
