In recent years, high-profile fire incidents have led to increased scrutiny of the fire safety of our buildings, and many countries have strengthened their requirements for fire properties of building materials. This course looks at how stone wool insulation protects buildings from fire disasters and how its fiber makeup contributes to better outcomes when fires do occur.

The Role of Stone Wool Insulation in Achieving Passive Fire Protection
Due to its natural basalt rock and recycled slag composition, stone wool exhibits a number of unique and valuable characteristics, including its ability to resist fire. The benefits of stone wool insulation are ideal for sandwich wall panel (SWP) applications given the fact that stone wool is non-combustible, inorganic, and will not contribute to harmful smoke or toxic gases in the event of a fire. This article looks at stone wool insulation’s unique ability to achieve passive fire protection.

Achieving Aesthetics and Energy Efficiency with Stone Wool Insulation
In this article focused on aesthetics and energy efficiency of stone wool, fire protection was a major component of the projects spotlighted here. Non-combustible materials go hand-in-hand with the goals of achieving energy efficiency and beautiful, safe buildings.

Why Non-Combustible Stone Wool Insulation Makes Sense
Given that most fires occur in domestic dwellings, blocks of flats have a high safety risk potential in the event of a fire. Today’s modern multi-storey buildings tend to offer a complex mix of occupation, including offices, hotels, residential, retail and leisure facilities.

Rock and Slag Wool Insulation: Sustainable Choices for Conserving Energy
Rock and slag wool insulation offers a wide array of benefits for specifiers, designers and builders interested in using materials offering environmentally responsible characteristics and demonstrating proven performance. This article provides an overview of stone wool, including how it is naturally non-combustible and remains so for the life of the product.

Mineral Wool Applications: Fire Protection
The damage caused by fire in buildings is incalculable. Each year many lives are lost and injuries occur because of fire. This article looks at fire-resistant materials such as mineral wool that provide vital extra minutes in delaying the spread of fire, which helps save lives and limits the destruction of property.

As one of the tallest wood buildings in North America, exceptional fire protection was a primary goal for the Origine Condominium Tower project in Québec City, Québec, Canada. Extensive pre-construction testing showed Origine’s building envelope—including a continuous layer of exterior stone wool semi-rigid board insulation—could exceed existing fire safety standards.
