Benefits at a glance

Glass Roof Fire Resistance F30/REI30


  • Fire resistance with the functional integrity of the complete system tested and certified to 30 minutes
  • General Technical Approval (abZ) according to DIN 4102-13 (F30) and classification according to EN13501-2 (REI30)
  • As a self-supporting structure, no costly supporting elements or additional certificates are required
  • No optical compromises – This product has the appearance of the LAMILUX Glass Roof PR60
  • The test under load (REI30) replicates real conditions through to extreme weather events
  • The system bears the DVS quality seal and is certified according to DIN EN 1090-3
  • Resistance to external fire exposure from flying sparks and radiant heat with classification B,roof(t1) according to DIN EN 13501-5



Optimised sealing and drainage system

  • Efficient ventilation of glazing rebates and controlled drainage of water and condensate
  • Overlapping, multi-layered sealing system, designed without direct joints and a secondary drainage system in the inner sealing layer
  • Joint-free, continuous drainage level on the mullion / rafters
  • Increase and improvement of the surface temperature on the glass edge and subsequent reduction in risk of condensation

Active energy management

  • Reduction of heat loss in the frame
