CONTRAFLAM in Kolkata is a single or multi-chamber fire-resistive glass made of two or more sheets of toughened safety glass. The cavity between the glass sheets is sealed to be completely moisture-resistant, is then filled with an environmentally friendly, transparent and UV-stable intumescent interlayer that reacts when exposed to fire. The level of fire resistance required determines the number of sheets of toughened safety glass and interlayers included.
In the event of fire, it offers full heat insulation for the compartmentalization of fire. This product satisfies the highest demands of fire protection while offering robust handling and UV stability, with numerous configurations available.
