CONTRAFLAM Structure

Butt-joint fire-resistant glazing system for interior & exterior applications*

CONTRAFLAM Structure redefines transparent fire protection by offering a fireproof glass solution that eliminates vertical frame profiles. Designed for architectural glass solutions where safety meets aesthetics, it creates an uninterrupted expanse of glass, joined only with silicone. This fire-resistant glass system supports modern design for interior or exterior applications while ensuring the highest safety standards.

Made from CONTRAFLAM fire rated glass, this system achieves the mechanical resistance needed to support interior wall line loads, delivering both safety and visual continuity.

Performances

CONTRAFLAM Structure is designed to create safe escape routes by containing fire and smoke while allowing natural light to flood buildings. When exposed to fire, its opaque insulating interlayer blocks visibility to the flames, helping reduce panic and guide emergency responders to the fire source.

This architectural glass solution maintains fire resistance up to EI120, offering superior safety without compromising design. The butt-joint glazing system eliminates bulky vertical frames, ensuring maximum transparency. Its thickness can be adjusted to meet mechanical resistance requirements, making it an ideal solution for high-traffic areas.

FAQs

How is CONTRAFLAM Structure tested for fire resistance?

CONTRAFLAM Structure undergoes fire resistance tests in accordance with international standards. It is subjected to temperature and pressure conditions as specified in the standards to ensure it can contain flames and smoke for the rated duration as well as limit the unexposed side temperature.

What are the different classes of CONTRAFLAM Structure?

The system offers fire-rated classifications from EW30 up to EW60 and EI30 up to EI120, providing varying levels of fire resistance based on project requirements.

Can CONTRAFLAM Structure be customised for specific applications?

Yes! The system is fully customisable to match architectural, safety, and performance requirements. Vetrotech’s design-assist team helps tailor solutions to meet your exact needs.

What is the maximum size for CONTRAFLAM Structure?

The standard maximum size is 2000mm x 3800mm, while CONTRAFLAM Structure Mega allows sizes up to 1800mm x 4480mm for EI30 classification.

Related Classification

EW classification

Class EW (Integrity & Radiation) fire-rated glass reduces the transmission of radiant heat, limiting fire spread and creating safer separation distances.
 

E classification

Class E (Integrity only) fire-resistant glass acts as a barrier to prevent flames, smoke, and toxic gases from passing through.
