Durability

We think buildings should be built to last. Our stone wool insulation is so durable, it can last at least 65 years – but probably longer – with no degradation in its quality or performance.

Why does durability matter?

Whether it’s our homes, schools, hospitals or any number of other examples, buildings play important roles in our lives and we can probably agree they should be built to last – with materials that last. Based on volcanic rock, stone wool is remarkably durable. Our insulation is non-combustible and moisture repellent with excellent thermal and acoustic properties, which don’t deteriorate over time. What’s more, it can be recycled over and over with no loss in performance.

By using durable materials, we ensure that the buildings we care about are preserved for future generations, avoiding unnecessary resource consumption and reducing waste. You know what else? Buildings "built to last" require less frequent maintenance, repairs and renovation, which means lower costs and less disruption for occupants and activities in the building.

Did you know?

Through testing of our products found in old buildings -- most recently during a renovation of an airport hangar in Copenhagen -- we know that our stone wool insulation can last at least 65 years (and probably longer), maintaining its thermal and other performance properties and supporting the long-term value and sustainability of buildings.

And since stone wool is moisture repellent and non-hygroscopic, which means it won't absorb water from the surrounding environment, it helps protect buildings from mildew and mould growth, rot and also corrosion.

Check out our case studies, including the one about Ferrero Group's production site in France, where they built a temperature-controlled storage space to last. Using stone wool insulated sandwich panels, they helped secure the ideal storage facility for one of Ferrero Group's flagship products: Nutella.
