Gz60+GzKV+GzKF • Fire resistant door and transfert grilles

  • Fire resistant grilles
  • Rectangular
  • 60min

Rectangular fire resistant ventilation grilles GZ60 are applicable for fire compartimentation within buildings. The grille is made of blades, which swell at a temperature of approximately 100°C, thereby closing the opening. The fire resistant grilles are only applicable in systems without pressure (natural ventilation). Due to its form, in combination with fixed finishing frame GZKF and variable counterframe GZKV and possibility of availability in 3 different colors, it forms an aestetic alternative on existing fire resitant grilles
