,The most versatile solution for applications demanding maximum Fire-Resistive protection in the largest possible dimensions.
CONTRAFLAM 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.
  • Available in single, double, or triple glazing (IGU) 
  • Rated for full fire-resistance from 45 to 120 minutes 
  • Symmetrical 1(B)1 impact resistance (EN 12600)
  • Extended exposure time of 5,000 hours UV stability versus standard 2,000 hours 
  • Large variety of low-E and solar control coatings  
  • Exceptional U values (double glazing ≥ 0.9 W/m²K, triple glazing ≥ 0.5 W/m²) 
  • Available in large dimensions 
  • Moisture- and pressure-resistant edge sealing for extended durability 
  • Excellent acoustic insulation properties 
  • Many design and comfort options 
  • Manufactured locally for fast delivery and reduced CO2 emissions
  • Can serve as laminated safety glass  
  • Easy, secure handling and installation 
,Butt-joint fire-resistant glazing system for interior & exterior applications (under specific conditions)
CONTRAFLAM Structure sets new standards in the design of transparent fire protection. The floor-to-ceiling glazing system provides a continuous, uninterrupted glass wall, joined only with silicone.
