OGRAX-VENT

Description of fire-retardant material

System Ograx-VENT is a basalt foil material Ograx-BM and flame-retardant adhesive composition Ograx-K. Fire retardant basalt material has low thermal conductivity, thus preserving the integrity of the surface of the duct in case of fire and as a result, prevent the spread of fire through the ventilation system.

Installation

  • Pre-clean the surface of any debris, rust, remove old coatings, if necessary, apply a primer. The surface must be dry.
  • Work at a temperature not below +5 ° C, relative humidity less than 85%.
  • The adhesive composition mix thoroughly.
  • Apply the adhesive composition of the protected surface with a spatula, brush, air or airless spray.
  • Cutting basalt fireproof rolled material into pieces of desired size.
  • Wrap the surface of the protected structure coated with a layer of wet adhesive foil fireproofing material outward. The edges of the material are mounted with overlap of 50 mm.
  • If necessary additionally fastened AUR steel wire as a clamp. At the request of wire and aluminum tape to close the joints.
  • Use personal protective equipment. In case of contact with eyes rinse thoroughly with water.
