CONTRAFLAM Structure
CONTRAFLAM Structure sets new standards in the design of transparent fire protection systems. The floor-to-ceiling glazing system provides a continuous, uninterrupted glass wall, joined only with silicone.
Made of CONTRAFLAM fire-resistant glass, CONTRAFLAM Structure is engineered to achieve the mechanical resistance required to support interior wall line-loads and offer superior edge aesthetic.

Performances
CONTRAFLAM Structure helps create safe escape routes, making it ideal for use in busy areas. When activated, the opaque insulating interlayer blocks the view of the fire, which minimizes panic and guides emergency services by indicating where the fire is located.
The original flush butt-joint glazing solution eliminates vertical frame profiles while achieving ratings of up to EI120. Because it allows for minimal framing elements, the crisp and clean lines of CONTRAFLAM Structure helps flood buildings with natural daylight without compromising on safety. Its glass thickness can be increased to achieve the mechanical resistance required to support interior wall line-loads.

Related Classification
EW classification
Class EW (Integrity & Radiation) fire-rated glass limits the transmission of radiant heat, reduces the risk of fire spread, and creates safer separation distances.
E classification
Class E (or Integrity only) fire-rated glass provides a barrier against the passage of flames, smoke, and hot, toxic gases.
