Fire safety in buildings begins with the materials used in construction. Insulation, which is present throughout a building envelope, plays a critical role in determining how a structure responds to fire.
Fire Classification Standards
European fire classification standards (EN 13501-1) categorize building materials from A1 (non-combustible) to F (no performance determined). Selecting A1-rated insulation materials eliminates the insulation as a potential fuel source in the event of a fire.
Lessons from Major Incidents
Several high-profile building fires have highlighted the dangers of using combustible insulation materials in facade systems. These incidents have led to stricter regulations and increased demand for non-combustible insulation solutions across many countries.
Aerogel as a Fire-Safe Solution
Silica aerogel insulation is classified as A1 non-combustible under European standards. It does not contribute to fire spread, does not produce toxic smoke, and maintains its structural integrity at temperatures exceeding 600 degrees Celsius.
Beyond Compliance
While meeting minimum fire safety codes is essential, specifying A1-rated insulation like aerogel provides an additional margin of safety. This is particularly important in high-rise buildings, healthcare facilities, and other structures where evacuation may be complex.
