How Should I Store & Handle Rockwool Insulation?

Rockwool insulation slabs have a soft, fibrous texture, similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it.When it comes to storage, we advise that you store the slabs inside.

Is Rockwool Insulation Fireproof?

Rockwool insulation’s fire performance rating is excellent. The slabs can withstand temperatures up to a whopping 1,000 celcius. Rockwool insulation slabs are classed as A1, the highest possible level on the Euroclass system, which means that they are fire retardant in accordance of BS EN 13162.

Is Rockwool Waterproof?

Rockwool insulation is moisture resistant and vapour permeable. Engineered to repel water, water will drain away rather than soak into the insulation, while gaseous water vapour will simply pass through it. Therefore, if Rockwool gets wet, you can dry the material out and it will maintain its original performance characteristics.
