PAROC Stonewool insulation products and solutions

Engineered to perform
Low Emission Insulation

The PAROC®Pro Wired Mat LE delivers for industrial facilities looking to reduce downtime, improve efficiency and ensure a safer working environment for employees.

We have created a new generation of binders based on biobased ingredients. This innovative binder emits less mono isocyanates and less formaldehyde emissions compared to known competing stone wool products, and as a result, it provides the lowest emissions available for stone wool insulation products.

With low emission and a reduced need for preventative safety measures during and after installation, it’s the smart choice for a cleaner, more efficient facility – where everyone can breathe with ease.

The most sustainable energy is saved energy

In the EU, buildings consume approximately 40% of all energy. The question is: how could we reduce our energy consumption? The simple answer: by improving the energy efficiency of buildings with better insulation, as this has the potential to reduce the energy needed for heating and cooling, and free up energy for the rest of society.
