Using Stone Wool For Your Application

There are two types of mineral wool products: Glass wool and stone wool insulation. Stone wool insulation is engineered to be fabricated in OEM applications and comes in a variety of formats, densities and dimensions, making it easy to cut, bend, split, wrap and compress. It is made from volcanic rock, typically basalt and recycled materials.

See a webpage from our partner ROCKWOOL that describes the same material and it’s benefits that will be covered in this article, here

In the following post we discuss seven reasons you should use stone wool insulation for OEM applications.

  • Fire Resistant
  • Water Properties
  • Sound Absorbent
  • Thermal Properties
  • Robustness
  • Aesthetics
  • Circularity

Stone wool has an unparalleled fire resistance, sound absorbency and thermal protection properties, making it the ideal choice for a variety of applications including laboratory incubators, insulated packaging, buses and railcars, appliances, fire/acoustic doors, office interiors, HVAC, and more.

Fire Resistant

A key feature of stone wool insulation is its resistance to fire. Stone wool products are non-combustible and will not develop smoke or promote flame spread, even when directly exposed to fire. Some stone wool products can even resist temperatures up to approximately 1177°C (2150°F) which is even hotter than most fires will ever reach.

Water Properties

Stone wool is water repellent yet vapor permeable meaning that the long-term R-value is unaffected by moisture over time. This is due to the inherent drying potential of the product which is also resistant to rot, mold and mildew growth, contributing to a safer indoor environment.

Sound Absorbent

The non-directional structure of stone wool insulation is denser than traditional insulation products which helps to absorb acoustic waves and can reduce the intensity and propagation of noise. Stone wool also effectively reduces airflow and sound transmission, while providing higher airflow resistivity for improved sound attenuation.

Thermal Properties

Using Stone wool makes living and working conditions more healthy and comfortable, helping people to thrive, especially in urban environments. Temperature maintenance can dramatically reduce heating, cooling, and ventilation costs, and reduce a building’s carbon footprint. This helps you to save energy by maintaining optimum indoor temperature and climate. 


In land-scarce urban areas, more and more people are working and making their homes in high-rise buildings. These structures can be brilliant solutions to the challenge of safely housing a growing population. Stone wool provides increased performance and greater stability with lower costs.
Additionally stone wool retains its characteristics over time which means reducing maintenance over the life of the home or building. Even with changes in temperature and/or humidity over long periods of time, there are minimal changes in the size or performance of stone wool solutions.


When people live and work in aesthetic spaces, they feel comfortable and motivated. Environments in which people enjoy spending time can improve social cohesion and make neighborhoods safer and healthier. Stone wool can help you match your performance needs with your aesthetic goals. 


Rock is one of the most abundant raw materials on the planet, but we still need to make better use of our planet’s resources. We have developed our technology in a way that allows us to use waste from other industries as alternative raw material. This results in a reusable and recyclable material who’s use doesn’t end after its first application. 

Here at Peerless Hi-Temp we machine a variety of mineral wool products for original equipment manufacturers, general contractors, musicians and end users. We help our customers consider the use of the product and select the right material specific to the OEM application creating a custom solution for high quality performance components before, during and after fabrication.
