OGNEZA-OVM fire-resistant ventilation mastic (OGNEZA OM-VENT system)
Non-combustible mastic for fire protection of air ducts — an alternative to basalt materials; EI 30, EI 45, EI 60 per GOST R 53299-2019.

OGNEZA-PM (PGZ) combines two functions — fire protection and sound insulation. The split steel body contains an intumescent insert, a layer of mineral wool and a fire-stopping sealant; the product reduces noise by at least 30 dB and provides fire resistance of up to 180 minutes. The sleeve is fitted on PP, PE and PVC pipes in residential and administrative buildings, and casting into concrete is permitted. The operating range is from −50 to +80 °C; the body is red or another colour to order.
