CAFCO® 300
Application

For internal and external use. Suitable for a wide range of educational, leisure and entertainment centres, and commercial projects. Typical substrates include non-primed ('ginger') and primed steel, concrete structural frames and return air plenums.

Description

Spray or trowel applied, single package factory controlled premix, based on vermiculite and gypsum, for internal use. A lightweight coating that provides very efficient fire resistance with minimal thickness to steel and concrete frames, metal floor and roof decks, and to return air plenums.

Features and benefits:

  • 30–240 minutes' fire resistance.
  • Part of a Promat steel package.
  • Internal and external applications.

Fire protection:

Structures protected with CAFCO® 300 have undergone extensive fire resistance tests up to 240 minutes in approved independent laboratories to recognized standards, including:

  • UK: Consult manufacturer for details.
  • USA: ASTM E11).
  • France: August 1999 Ministry Decree.
  • Belgium (NBN S21-202).
  • Germany: DIN 4102:1977-09 and DIN EN 1363-1:1999-10.
  • European standard: ENV 13381-4. The fire resistance test results relate solely to the constructions tested and test conditions imposed.

- Product thickness:

  • The thickness of the fire protection for a given period of fire resistance in a cellulosic type fire relates to the exposed surface area-to-volume (A/V) ratio of the section.
  • All column and beam sections have their own specific A/V ratio. Consult manufacturer to establish the A/V ratio for a particular beam or column section. Consult the manufacturer's literature to ascertain the thickness of CAFCO® 300 that meets the required period of fire resistance for I-section beams and H-section columns and hollow section beams and columns.

For advice on thickness calculations for hollow sections, cellular beams, castellated sections, composite floors, upgrading of concrete slabs and more complex situations, contact manufacturer's technical services department.
