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 toughness. ROCKWOOL insulation is dimensionally stable: it just keeps performing, decade after decade.

ROCKWOOL stone wool insulation can also be used to create products that withstand sustained or heavy loads. Millions of square meters of concrete floors have been laid on top of ROCKWOOL insulation all over the world (with no evidence of long term creeping).

ROCKWOOL insulation also delivers excellent thermal performance as well.

Improving thermal performance

ROCKWOOL insulation derives its excellent thermal properties from tiny pockets of air trapped within the physical structure of the stone wool.

ROCKWOOL insulation continues to work throughout the lifetime of the building. As well as reducing the heat needed to keep buildings warm in winter, stone wool insulation also maintains a cool interior temperature in summer. It’s energy efficient as well as being environmentally friendly all year round.

ROCKWOOL insulation is not just for new builds. An effective way to improve the thermal performance of existing buildings is to add insulated external render systems such as ROCKWOOL ROCKSHIELD. This causes minimal disruption to occupants and will cut fuel bills year after year.
