Isover history

Our offer

Since 1937, we imagine, manufacture and deliver a broad range of insulation solutions made of different materials.

A multi-material offer

Mineral wool is a porous and flexible material that traps the air, making it one of the best thermal and acoustic insulating materials. Mineral wool is incombustible and does not fuel fire or propagate flames.

At Isover, we produce 2 types of mineral wool products: 

  • Glass wool: Isover glass wool solutions are mainly made from sand and recycled glass. They improve thermal comfort, by reducing heat loss in winter or heat gains in summer. They also have excellent sound absorption properties. Over the past 80 years, we have constantly improved our solutions to improve their mechanical, fire, thermal and acoustic performances. 


  • Stone wool: Isover stone wool is made of volcanic rock raw materials and recycled stone wool waste. It combines mechanical resistance with good thermal performance, fire safety and high temperature suitability.

Our commitment


Our construction brands contribute to achieve this vision thanks to a concrete commitment: we care about building better for people and the planet by offering solutions that deliver sustainability and performance.

For Isover,  this commitment translates into concrete actions.

  • It means making our solutions available across the world thanks to our worldwide footprint.

  • It means that we constantly innovate to satisfy customers’ needs. We developed high performance insulation products such as the Isover MULTIMAX Lambda 030 glass wool with the best thermal performance on the market.

  • It means we commit to share our expertise on insulation and help professionals to build better in all aspects.

  • It means investing in recycling programs. In France, Isover launched the first closed-loop recycling service for construction and demolition glass wool waste.

  • It also means rewarding our customers’ loyalty via dedicated communities and clubs.
