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 reduces the 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.

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.

Key benefits

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

Our products

  • help in the reduction of heat loss and CO2 emissions while saving on your energy bill
  • work as a buffer in the construction, delaying and reducing peak temperatures  
  • are part of the key solution to deliver 50–90% potential energy savings in new and existing buildings
  • have tiny pockets of air in the structure of the stone wool to keep hot air out in warm climates and retain hot air in cold climates
  • maintain their density so they perform at their peak throughout the lifetime of the building


The ROCKWOOL Group’s expertise is perfectly suited to tackle many of today’s biggest sustainability and development challenges, from energy consumption and noise pollution to fire resilience, water scarcity and flooding. Our product range reflects the diversity of the world’s needs, while supporting our stakeholders in reducing their own carbon footprint.


With the urban population growing every day, we need to find ways to house everyone in our cities in a way that helps them thrive. We are the leading provider of fire resilient stone wool products. We provide products and solutions for all major application areas for both residential and non-residential buildings.


Our wellbeing goes hand-in-hand with the comfort of the environment where we work, live, learn, play or even – in the case of a hospital – recover, why stone wool solutions is crucial in non-residential areas and in protecting modern life.


Industrial and technical insulation are used to insulate pipes, ducts, columns, tanks, vessels and boilers in industrial plants and power stations. Another important segment is the marine and offshore market where the noncombustible properties of stone wool insulation ensures highest fire safety and comfort on board of ships and offshore platforms.


We develop and supply versatile and innovative products that help global industries to improve quality of life. Our products are used in a wide range of applications, including friction, water management, tracks, coatings, gaskets and fences.


We supply innovative and sustainable stone wool growing media solutions for the professional horticultural sector, based on Precision Growing principles. These solutions are, amongst others, applied for the cultivation of vegetables and flowers, such as tomatoes, cucumbers, sweet peppers, egg plants, roses and gerberas.
