All ROCKWOOL stone wool insulation is made from volcanic rock, making it naturally durable and stable over the lifetime of a building.
The unique physical structure of ROCKWOOL insulation keeps its shape and resilience. ROCKWOOL insulation is dimensionally stable: it just keeps performing, decade after decade.
ROCKWOOL insulation also delivers excellent thermal performance.
Improving thermal performance
ROCKWOOL insulation derives its excellent thermal properties from tiny pockets of air trapped within the structure of the product.
ROCKWOOL insulation continues to perform throughout the lifespan of the building. As well as reducing the heat needed to keep buildings warm in cold weather, stone wool insulation also maintains a cool interior during the warmer months.
