Since we can combine the PYROBELITE and PYROBEL glass with laminated, coloured, reflexive and low-emission glass, we offer a wide range of glass panes combined with fire-resistant glass. This type of glass may perform different functions, such as: protection against burglary and noise, thermal and light insulation. As we have possibilities to process the fire-resistant glass, all our fire-resistant products are available with very short lead times.
It must be remembered that the process of transforming fire-resistant glass into double-glazed units may not be commissioned to random manufacturers. That process requires specific manufacturing discipline due to the necessity of protecting the glass edges from coming into contact with the gel bonding of the panes by means of special aluminium foil. Direct contact with aggressive substances in the air or in water may lead to the fire-resistant glass layers losing their fire-resistant properties.
Similarly, special precautions must be applied during the fitting of double-glazed sheets in window frames in order to prevent the breaking of the protective layer securing the edges.
The destruction of the protective layer may lead to the glass losing its properties and result in quicker flame propagation, as well as the inability to evacuate people from the building.
In the event of the time spell between the glass manufacture and fitting in the window frame being very long, the inside surface of the fire-resistant glass must be protected from theUV radiation, as it is not protected by means of the PVB foil.
Before orders are processed, clients ought to be notified of the general criteria defined by glass manufacturers, which must be followed during its application. The company which processes the glass sheets into double-glazed units is not responsible for the loss of the fire-resistant properties as a result of inappropriate fitting.

What should you know when buying fire resistant glass?
The information provided below contains additional remarks which enable interested parties to find out more details associated with purchasing fire resistant glass units.
Due to the requirements with respect to fire resistant glass units, the production and ordering must involve additional procedures which is not the case with other products.
The standard market offer of Press-Glas comprises of double glazed fire resistant glass, designed for use in interior or outdoor partition walls. Single glazed fire resistant glass units for outdoor partition walls are available in the non-standard market offer.
New cutting and glazed lines for fire resistant glass units enable the production of glass units with dimensions of 2,700 by 5,000 mm. The maximum dimensions used are however limited by technical approvals that define the maximum homologated dimensions of the sides, which normally do not exceed 2,700mm. While ordering glass units it is essential to check the maximum dimensions allowed in the approval each time.
Due to the stability of work with regard to the glass units under the force of fire spacerbars of zinc steel or aluminium are used in the production of double glazed fire resistant glass. The use of the so-called warm edges is limited. Up to now the possibility of using plastic edges has not been considered. The thermal bridge which causes excessive infiltration of heat along the edges of the glass can be immediately reduced by the use of spacerbars of precious steel. Double glazed units are offered as standard and filled with air in a spacerbar of 8mm width, while the full range of spacerbars involves widths between 6 to 24mm. In the case where there is a necessity to achieve the heat transmission coefficient of Ug = 1.1 W/mZK, then glass units are filled with noble gas known as argon, with a spacerbar of 16mm width.

*The classification of resistance has been presented on the basis of tests carried out for the complete system. In the case of using another system or elements of a different system to that shown in the approvals, the classification of fire-resistance may not be achieved.
In the case of ordering double glazed reflexive solar control glass and glass which is edged in mass, it is necessary to receive advice as to the possibility of application due to the limitations associated with the heating of fire resistant glass. This is associated with the phenomenon of heat energy absorption in the glass mass, which in effect can cause degradation of the gel, which is a component of fire resistant glass, under the impact of excessive temperatures.
Construction firms that order double glazed glass often avail of forms which they prepare themselves. However, in the case of ordering fire resistant glass units, orders should be made using forms prepared by Press-Glas. It is necessary to provide the name of the glazing system which will involve the use of glass units and the valid number of the technical approval. Moreover, the form containing the order should include the information provided in the table below:
| No. |
Glass unit external + position of coating |
Type of spacebar + width (mm) |
Inside Glass unit |
Width (mm) |
Height (mm) |
Quantity |
Glazing system (name and number of technical approval) |

Press-Glas marks fire resistant glass units known as Pyrobel and Pyrobelite with a permanent stamp which includes the following:
- marking the type of fire resistant glass: Pyrobel or Pyrobelite,
- marking of classification as regards resistance,
- identification symbol of the producer of the glass units: Press-Glas,
- month and year of production with regard to the glass unit.
Additionally, glass units for inside use are marked with an appropriate label aimed at clearly specifying the designed glazing application.
Assessment of defects in fire resistance glass units is carried out on the basis of the norms known as PN-EN ISO 12543 entitled “Laminated glass and safe laminated glass”.
