Fire-prevention glass Pyrobel 8

Fire-prevention Pyrobel 8 glass — laminated glass with colorless intumescent layer. In case of fire this layer changes the physical characteristics and glass turns into the rigid and opaque protective design allowing a glazing to keep integrity and heat insulation. Fire-prevention glass Pyrobel 8/8 EG provides two-way protection.

Technical characteristics of the PIROBEL 8 fire-prevention glass:

  • According to GOST 53308-2009
  • Fire-resistant glazing of E30 I15 W30

* (E) integrity. guarantees lack of through cracks or openings through which the flame and products of burning can penetrate;
    (I) the heat-insulating ability, prevents the transfer of heat to the protected space by the radiation
   (W) limiting the density of heat flow

Fire resistance limit:

  • Integrity — 30 minutes
  • Heat insulation — 15 minutes
