Technical Approval: ITB no. AT-15-8196/2016

Certificate of Compliance: ITB-1918/W

National Declaration of Performance KDWU/HZ/01/2017


mcr Isoverm 825 ensures the obtaining of resistance classes:

  • R15 up to R240 for steel structural elements of massiveness factor U/A≤400m-1

mcr Isoverm 825 spray system is perfect for specialist industrial buildings, including: power plants, refineries, chemical plants, platforms, etc., where hydrocarbon fire hazards exist.

 

Fire resistance of the system is ensured by proper selection of thickness of the sprayed mass in accordance with massiveness factor of the proofed element, designed fire resistance class, and critical temperature of the steel.

 

mcr Isoverm 825 fireproof system comprises:

  • mcr Tecwool 825 spray mass
  • steel net
  • steel pins

  • high durability
  • quick application
  • own mass of fireproof insulation negligible in static calculations
  • biologically neutral, non-toxic
  • resistant to flaking, rotting and fungi
  • no corrosive effect on steel surface
  • "lamb" external surface texture
  • dry density 402 ± 10% kg/m3
