CONTRAFLAM Structure
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. 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.

Design Applications
A butt-joint family to match all design expectations with the robustness of toughened glass.
Flush joint blend seamlessly with glass surfaces
CONTRAFLAM STRUCTURE
The first fire-resistant butt-joint tempered glass solution. The look and feel of a “structural glazed” unit.
Minimized sight-lines to maximize daylight and transparency
CONTRAFLAM STRUCTURE ELEGANCE
Thinnest sight-line of any tempered butt-joint fire resisting glass type. Maximum daylight and transparency.
Discretely blend with interior tones
CONTRAFLAM STRUCTURE VIBRANCE
Discreet matching with interior colour tones. The vertical edges, perfectly delineated with ceramic paint, are available in any Pantone or RAL colour.
Accentuate with complimentary colours
CONTRAFLAM STRUCTURE VIBRANCE
Accentuate with complimentary colours. Ceramic frit back-painted vertical edges in any Pantone or RAL colour.
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 reduce the risk of fire spread and create safer separation distances.
E classification
In the event of a fire, Class E (or Integrity only) fire-rated glass provides a barrier against the passage of flames, smoke, and hot, toxic gases.
