Even if not used primarily for fire protection, due to its non-combustibility ROCKWOOL insulation does not fuel or spread fire by releasing heat, smoke, or burning droplets.
All ROCKWOOL insulation is made from rock, making it naturally durable and stable over the lifetime of a building. This means it never needs replacing.
The unique physical structure of ROCKWOOL stone wool keeps its shape and toughness, and it is not affected by changes in temperature or humidity. ROCKWOOL insulation is dimensionally stable: it just keeps performing, decade after decade.
ROCKWOOL insulation can be used even under extreme conditions because it retains its insulation properties in both very low (e.g. oxygen installations) and very high (up to 1000°C) temperatures.
ROCKWOOL products also deliver excellent thermal performance. It derives its excellent thermal properties from tiny pockets of air trapped within the physical structure of the stone wool, allowing it to keep the heat out in hot climate and the warmth inside in cold regions.
This means you can create a pleasant and stable indoor temperature year after year, while saving energy and money for cooling/heating.
