Thermal properties

The optimal temperature, whatever the weather outside

Maintaining a consistent indoor temperature is better for you and for the environment

It makes living and working conditions more healthy and comfortable, helping people to thrive, especially in urban environments. Temperature maintenance can dramatically reduce heating, cooling, and ventilation costs, and reduce a building’s carbon footprint. ROCKWOOL insulation is a highly flexible material, which works in all spaces as a buffer against fluctuations in temperature. 

By reducing airflow and heat flow, our products maintain their shape and density, so they perform at their peak throughout the lifetime of the building. It’s part of our commitment to building sustainable cities that promote human flourishing.

Our products derive their thermal properties from tiny pockets of air trapped within the physical structure of the stone wool. These air pockets allow the insulation to keep hot air out in hot climates and to retain warm air in cold climates.

Did you know?

Damp and mould can have a detrimental effect on the health of building fabric, the thermal performance of the building, and the respiratory health of occupants. Understanding breathability is crucial to creating healthy, durable, working buildings.

Stone wool products create healthy indoor environments for everyone

As well as maintaining optimal temperature, stone’s thermal properties mean it can protect people and properties from mould and other fungi. So architects can create buildings that not only shelter us from the weather, but also provide a safe and comfortable indoor environment that empowers us to lead healthy lives. 

Buildings, like people, need to stay healthy. Stone wool is vapour-permeable, which means it allows moisture to pass through walls and out of the building. This protects buildings against rot, mould, and humidity damage.
