ET VENT — fire insulation for air ducts
Air duct fire protection system of foil-faced basalt MBOR F on PLAZAS adhesive compound: fire resistance from 30 to 240 minutes.

Light-gauge thin-walled steel structures (LSTK) are protected with a separate TIZOL system, ET LSTK. It is based on MBOR-F basalt material on PLAZAS adhesive compound, while EURO-LIT board is used for I-sections and Z-profiles. Fire resistance ratings are R15–R90; NSOPB certificates have been issued for LSTK and separately for Z-profiles. Applications include residential buildings, including those of 6 storeys and above, warehouses and long-span structures; the warranty service life is at least 25 years.
