How to choose the right fireproof spray depending on the type and location of the fire?

mcr Tecwool F belongs to the group of so-called fire-retardant light sprays, i.e. those with a low density of the spray mass. It is intended for buildings where it is required to increase the fire resistance of structural elements exposed to standard (cellulose) fires.

The fire resistance of the system is ensured by the proper selection of the thickness of the sprayed mcr Tecwool F compound.

mcr Tecwool F provides the following resistance classes:

- R15 to R240 for steel construction elements with a mass factor U/A≤400m-1

- R30 to R240 for reinforced concrete elements

- REI 60 and REI 120 for beam and hollow ceilings

- REI 120 to reinforced concrete ceilings on a trapezoidal sheet

The mcr Isoverm 825 spraying system is perfect for tunnels and industrial buildings, such as: power plants, refineries, chemical installations, platforms where there is a risk of hydrocarbon fires.

The fire resistance of the system is ensured by proper selection of the thickness of the sprayed mcr Tecwool 825 mass, depending on the massiveness factor of the protected element's cross-section, the required fire resistance class and the critical temperature of the steel. mcr Isoverm 825 provides resistance classes from R15 to R240 for steel construction elements with a U/A ≤400m-1 mass factor.
