CONTRAFLAM

A High-Performance Fire-Resistant Glass Solution for Maximum Protection

CONTRAFLAM fire-resistant glass is a versatile and highly effective fire protection solution designed for applications that demand maximum EI-class protection in large dimensions. Whether for interior or exterior applications, this fire-rated glazing provides full heat insulation, preventing fire spread while maintaining transparency under normal conditions.

Composed of single or multi-chamber toughened safety glass, CONTRAFLAM features a UV-stable, transparent, intumescent interlayer that reacts when exposed to heat. Upon activation, it expands into an opaque barrier, blocking fire, heat, and smoke for up to 120 minutes, helping protect people and property.

Performances

When exposed to fire, CONTRAFLAM fire-resistant glass activates its transparent intumescent interlayer, which expands into a heat-blocking, opaque foam. This prevents heat transfer for up to 120 minutes, ensuring compartmentalisation of fire and limiting fire spread.

With high UV stability, impact resistance, and extended durability, CONTRAFLAM is the gold standard in fire-rated glass solutions.
