Rock Doesn't Burn
Roxul stone wool resists temperatures up to approximately 1177°C (2150°F). It can act as a fire barrier, when used in conjunction with a fire sealant material, against the spread of the fire and provides valuable extra minutes to save people and property, and reduce environmental damage.
Fire resistance describes how well a building component can - for a stated period of time - hold back fire and prevent it from penetrating from one room to another. The basic criteria used to characterize the fire resistance of a product are:
- Flame spread
- Smoke development
- Non-combustibility
Fires Involving Insulation Materials
In case of fire, the choice of insulation material can become a vital one in terms of casualties, material or environmental damage. Roxul insulation is non-combustible and withstands up to 1177°C (2150°F). It can act as a fire barrier. Combustible insulation, on the other hand, can fuel the fire and cause it to spread.
Pollution
Every day emissions from fires have a serious impact on the environment. Not only are the combustion gases toxic at the site of the fire, but during a fire, very large quantities of particulates are also released into the environment. The particles consist, among others, of soot, tar, and unburned materials.
Flame Retardants
Roxul stone wool is made from basalt rock and slag, and this combination results in a non-combustible product. There are no added flame retardants in Roxul products. Combustible insulations often need to have chemicals added to make them less flammable.
