RANGE VIT PROTECT | OURS FIRE-RESISTANT GLAZING

STOP FIRE

STOP FIRE fire resistant glazing is a fire protection glazing.

For over 25 years, the AGC group has relied on VIT to stock, process and market its Pyrobel and Pyrobelite STOP FIRE ranges. VIT can provide you with flame-retardant and fire-retardant solutions in the shortest possible time throughout France.

AGC offers a complete range of fire-resistant glazing tested and approved by Efectis in accordance with European and national standards, providing a unique combination of light, transparency and fire protection, for all types of construction and fire-resistance duration.

STOP FIRE, Pyrobelite flame-retardant and Pyrobel fire-stop glazing, is transparent laminated glass composed of float glass and intumescent interlayers which, in the event of a fire, transform into cellular refractory and opaque screens that ensure the flame-tightness and thermal insulation of the glazed wall. The STOP FIRE range naturally offers glazing with fire resistance on both sides, with the option of being fitted as double glazing.

If the STOP FIRE range is to be used outdoors, the EG version is recommended, to protect the intumescent coating from the sun's UV rays. If the glazing is likely to be subjected to temperatures of over 50°C, it should be assembled as insulating glass with a solar control coating.

VIT also offers Pyrobel-T, fire-resistant glass in XXL sizes, available up to 2 metres wide and 4.5 metres high. In addition to its excellent fire resistance, Pyrobel-T is impact, UV and water resistant.

Their purpose is to protect people by creating a solid, reliable barrier to delay the spread of fire from one room to another for a set period of time, until the burning building can be evacuated.

What is the difference between flame-retardant and fire-resistant glazing?

Flame-retardant (E) or limited-radiation (EW) glazing consists of glass with one or more transparent intumescent interlayers. AGC's Pyrobelite glazing is rated EW30* in a variety of substrates such as wood, steel and aluminium. In the event of a fire, the interlayers expand to form a rigid, opaque protective barrier that prevents the passage of flames and smoke emitted by the fire for 30 minutes, as well as preventing panic by obscuring the glass.

* EW30 means flame-retardant glazing (EW) with a resistance of 30 minutes.

This glazing is generally used to prevent the spread of flames from one room to another, like Pyrodur® glass from Pilkington, Pyran® glass from Schott or Vetroflam® glass from Vetrotech (Saint Gobain).

Fire-stop or fire-tight and heat-insulating (EI) glazing consists of glass with several transparent intumescent interlayers. AGC's Pyrobel glazing is rated EI30 to EI120* in a range of substrates including wood, steel and aluminium. In the event of a fire, the intumescent spacers expand to form a rigid, opaque protective barrier which, in addition to its flame-retardant properties, will prevent the heat emitted by the flames from spreading for 30 to 120 minutes, depending on the Stop Fire product selected, and installed in accordance with the PV issued by Efectis.

* EI120 means fire-stop glazing (EI) with a resistance of 120 minutes.

This product is generally used in corridors or emergency staircases to allow people to escape unhindered. Pilkington also offers this type of product under the name Pyrostop®, Vetrotech (Saint Gobain) under the name Contraflam® and GlasTrösch under the name Fireswiss cool®.

The AGC range also includes glazing for Pyropane (DH) containment screens. This product is installed in the ceiling to prevent the spread of smoke to upper floors.

How is fire-resistant and fire-stop glazing tested?

Pyrobelite flame-retardant and Pyrobel fire-stop glazing is tested by the state-accredited Efectis laboratory to assess its fire resistance. To do this, samples of the entire structure (Stop Fire glass + aluminium, wood or steel joinery) are prepared and then installed in a test bench designed to simulate real fire conditions. The samples are subjected to an intense heat source to simulate exposure to a fire. The temperature, intensity of the fire and duration of exposure are controlled in accordance with current standards. During exposure to fire, the experts observe and record the behaviour of the glazing. They monitor flame propagation, smoke emission, deformation or breakage of the glazing, and heat transmission. Once the tests have been passed and the compliance criteria met, the glazing can be certified for between 30 and 120 minutes, with an EW or EI rating.

How should STOP FIRE products be stored?

Pyrobel and Pyrobelite AGC products must be stored in a dry and ventilated environment. Pyrobel and Pyrobelite glazing must be protected from sunlight and UV rays and always be placed and transported in an upright position.
If they are transported on racks or trestles, the glass must be held securely and tilted at an angle of 6° to 10° to prevent it from tipping over. For large volumes, the use of straps or vacuum lifting devices is recommended. Pivoting at an angle is prohibited
