Fire-prevention glass Pyrobel 21 - laminated glass with a few colorless intumescent layers. In case of fire, these layers change their physical characteristics and the glass turns into a rigid and opaque protective structure that allows to maintain the integrity of the glazing and insulation. Fire-prevention glass Pirobel 21/21 EG provides two-way protection.
* (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
