OGNEZA Bazalt-VENT air duct fire protection system
Fire protection of air ducts with PMBOR foil-faced basalt mat on OGNEZA-K adhesive or OGNET mastic; ratings from 60 to 240 minutes.

OGNEZA-K adhesive fixes mineral wool and basalt materials on air ducts and is used in flange joints and on facades. The binder is inorganic — silicate solutions and aqueous dispersions with fillers and fire retardants; per GOST 30244 the compound is non-combustible. The adhesive works from −60 to +100 °C and is part of the OGNEZA Bazalt-VENT air duct fire protection system. It is produced in 310 ml cartridges for a gun and in 30 kg buckets; ferrous metal is primed before application, galvanised steel is not. The service life is 30 years.
