mcr Tecwool F - spray protective mortar system for steel, reinforced concrete and bricked structural elements of building structures

Technical Approvals: ITB no. AT-15-8163/2013 and AT-15-9682/2016

Certificates of Compliance: ITB-1865/W and ITB-2468/W

National Declarations of Performance KDWU/HZ/02/2017 and KDWU/HZ/03/2017

 

mcr Tecwool F ensures the obtaining of resistance classes:

  • R15 up to R240 for steel structural elements of massiveness factor U/A≤400m-1
  • R30 up to R240 for reinforced concrete elements
  • REI 60 and REI 120 for beam and hollow brick floors
  • REI 120 for reinforced concrete floors on troughed sheet

mcr Tecwool F belongs to the group of so-called fireproof light sprays, i.e. featuring small mass of the spray mass. It is designed for general land building objects, where increased fire resistance of structures exposed to standard (cellulose) fires is required.

 

Fire resistance of the system is ensured by correct selection of the thickness of mcr Tecwool F mass applied.
