Our technology

POLFLAM fire-resistant glass meets the fire-insulation and fire-resistance criteria in compliance with the technical standard PN-EN 1363-1. It follows the technology developed by POLFLAM.

A fire-resistant glass unit is made of glass sheets. The space between them is filled with colourless hydrogel. The thickness of the hydrogel layer determines the fire-resistance class of the unit.

The hydrogel is produced at POLFLAM factory, according to the company’s own protected formula. The technology in use allows the company to produce fire-resistant glass of unique qualities.

The advantages of POLFLAM fire-resistant glass include

  • symmetrical design of the glass
  • large-sized fire-resistant glass panes: up to 2200 x 4200 mm
  • fire-resistant curved glass and glass sheets of irregular-edge shape
  • installation-friendly glass (blunt edges and no need of positioning)
  • high acoustic insulation index Rw – up to 48 dB [see for details]
  • high light transmittance factor – Lt up to 87.6%
  • UV radiation resistance – no need of PVB film
  • reaction to fire – B-s1, d0
  • top safety class 1/B/1 (according to PN-EN 12600)
  • resistance to temperatures from –40°C to +50°C
  • water-resistant edges (no need of protecting the edges with aluminium film)
  • high mechanical resistance – toughened glass
  • lower weight than the fire-resistant multiple-glazed units

POLFLAM also produces fire-resistant curved glass:

  • large dimension panes
  • large arching radius in all EI classes
