DOUBLE LAYERS FIRE-RATED GLASS
The double layer fire resistant provides both integrity and insulation against heat transfer. It consists of multiple layers of glass separated by fire-resistant interlayers, such as intumescent material or gel. These interlayers expand when exposed to high temperatures, forming an insulating barrier that helps prevent the transfer of heat. The glass has good fireproof and heat insulation properties, which meet the Class A of standards.
Features:
Applications:
- ✓ Exterior facades: EI-type fire-rated glass is commonly used in exterior facades of buildings, particularly in areas where fire safety regulations require the use of fire-rated materials. It allows for natural light transmission while providing fire protection and insulation.
- ✓ Stairwells and escape routes: Stairwells and escape routes require fire-rated glass that offers integrity and insulation. EI-type glass is ideal for these applications, as it helps protect individuals during evacuation and prevents the spread of fire and smoke.
- ✓ Industrial settings:EW-type fire-rated glass is often used in industrial settings where there is a higher risk of radiant heat exposure. This includes facilities such as power plants, factories, or chemical processing plants.
- ✓ Hazardous areas:Certain areas within buildings, such as storage rooms for flammable materials or server rooms, require fire-rated glass that can withstand radiant heat. EW-type glass is suitable for such applications, providing additional protection against heat transfer.
Product:
The double layer fire resistant has fire-resistant integrity and heat-insulating Class A(EI) fire-resistant glass, which has good fireproof and heat insulation properties, high transparency. It has longer fireproof time and higher transparency than other similar products with the same thickness,or the thinner thickness with the same fireproof time.

VETROTECH CONTRAFLAM
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)
