Insulation materialsMineral wool
Mineral wool
Saint-Gobain ISOVER uses natural and abundant raw materials (sand or volcanic rock), using fusion and fiberising techniques to produce glasswool or stonewool. The products obtained come in the form of a "mineral wool mat" consisting of a soft, airy structure
Intrinsic qualities
On Earth, naturally, the best insulator is dry immobile air at 10°C : its thermal conductivity factor, expressed in λ , is 0.025 W/(m.K) (watts per meter Kelvin degree). The thermal conductivity of mineral wool is close to immobile air as its lambda varies from 0.030 W/(m.K) for the most efficient to 0.040 W/(m.K) to the least.
With its entangled structure, mineral wool is a porous material that traps the air, making it one of the best insulating materials. The porous and elastic structure of the wool also absorbs noise in the air, knocks and offers acoustic correction inside premises. Containing incombustible materials, mineral wool does not fuel fire or propagate flames.
Innovative high-tech products
Glasswool is a very high-tech product. For the past 70 years, Saint-Gobain Isover has constantly improved its qualities and performance and each year files dozens of patents. Today's glasswool has nothing to do with that made in 1970. That is why at ISOVER, we talk about “glasswools” and not glasswool in the singular as there is such diversity in the range, in terms of features, performance and formats.
Thermal performance has been improved by 20 % in just 10 years: 15 cm of ISOVER wool (lambda 30 wool) insulates as much as 20 cm thick wool at lambda 40. Furthermore, ISOVER wools are now less irritant when bare and can also be covered with soft veils to improve laying comfort.
ULTIMATE, the new standard for top performance
The latest innovation from ISOVER provides a unique high-performance profile: it combines safety, comfort and easy handling.
The material is the result of many years of research and development during which time our efforts have been trained on meeting demands for safety and comfort. An important prerequisite throughout this rigorous development process has been Saint-Gobain Isover’s combined access to technical expertise coupled with a strategic, forward-thinking approach.
ULTIMATE
’s major new feature lies in its resistance to high temperatures, making it exceptionally capable of withstanding fire, a quality which can be attributed to its patented chemical composition.
