Factorylite Fire Resistance

Factorylite insulation is naturally non-combustible, manufactured from spun glass fibres with a very high melting point. Unlike other ceiling insulation products that rely on chemical treatments for fire resistance, Factorylite’s composition makes it inherently safe and non-toxic in high-temperature environments. Its fire-retardant performance lasts for the life of the insulation, with no degradation over time.

This makes it ideal for industrial and commercial roofs, where fire safety and thermal control are essential. Fibreglass products like Factorylite are often used in high-heat environments including furnaces, boilers, and ducting systems, thanks to their unmatched temperature resistance.

Fire Testing and Safety Ratings

✅ Non-combustible – Tested to SANS 10177 Part 5
✅ Class 1 Fire Index Rating – Tested to SANS 10177 Part 3
✅ Class A1, s1, d0 – Tested to EN 13823
✅ EUROCLASS A1 – Certified to EN 13501-1
✅ ASTM E-84 (USA) – Flame Spread Index: 20, Smoke Development Index: 5
✅ ASTM E-84 (WMF) – Flame Spread Index: 20, Smoke Development Index: 15

Factorylite stands out as one of the safest and most fire-resistant insulation solutions available in South Africa. Its combination of thermal performance and compliance with top international standards makes it the smart choice for fire-conscious construction projects.
