CONTRAFLAM

The most versatile solution for applications demanding maximum EI class protection in the largest possible dimensions.

CONTRAFLAM is a single or multi-chamber fire-resistant glass made of two or more sheets of toughened safety glass. The cavity so formed between the glass sheets is sealed to be completely moisture-resistant. It is then filled with an environmentally friendly, transparent and UV-stable intumescent interlayer that reacts when exposed to fire and offers full heat insulation for the compartmentalisation. The level of fire resistance required determines the number of sheets of toughened safety glass and interlayers included.

Performances

When exposed to fire, CONTRAFLAM’s transparent intumescent interlayers expands as an opaque foam to form a barrier to heat. This effectively limits the conduction of heat for up to 120 minutes to block the spread of fire and protect people on the non-fire side. The opaque insulating interlayer also blocks the view of the fire, which minimizes panic and guides emergency services by indicating where the fire is located.
