Fire Resistance

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.
The Fire Curve
Time is vital for fire fighters. It is essential that a building does not contain many combustible building materials, but has fire-resistant materials which can delay the spread of fire and provide many vital extra minutes to save people and property. Roxul stone wool insulation acts as a fire barrier that resists temperatures above 1,000°C.
