1) What is stone wool?

ROCKWOOL stone wool insulation is a natural product made from stone that makes a home more energy-efficient and protects it from fire, damp and mould.  

2) Why choose stone wool over other kinds of insulation?

Because it is made from stone, ROCKWOOL insulation is non-combustible. It can withstand temperatures above 1000°C. This is much higher than what could be expected from glass wool or foam-based insulation, making stone wool the safer choice to protect your home and your family from fire.

3) How much maintenance does ROCKWOOL insulation require?

ROCKWOOL stone wool insulation does not change shape, distort, or sag over time. And it is vapour-permeable so it resists the formation of damp and mould. Once it is fitted you don’t have to worry about it at all – for up to 55 years!

4) How do I obtain maximum comfort in my home?

Fitting ROCKWOOL stone wool insulation will keep your home cool in summer and warm in winter. It will also reduce noise, and give you the peace-of-mind that you are protected against fire.

5) What happens if ROCKWOOL insulation gets wet?

ROCKWOOL insulation is moisture-resistant yet vapour-permeable. In the event the insulation becomes damp or wet, the insulation will maintain the original performance characteristics when thoroughly dried.

ROCKWOOL stone wool insulation does not absorb water, which means that any bulk water that contacts the outer surface will drain and not penetrate into the body of the insulation.

6) Are ROCKWOOL products mould-resistant?

ROCKWOOL products are inorganic which provide no food source for mould to grow. ROCKWOOL products are tested for resistance to fungi– and pass with zero fungal growth.
