Non-vision fire-resistant ventilation grids GRNV1 Ei-60

Characteristics :

Non-vision fire-resistant ventilation grids GRNV1 Ei-60 react at low temperatures (from 100dgC°). The grids break quickly (usually within 3 minutes depending on heat exposure). They consist of thermoplastic sheaths filled with intumescent bands. The gates allow ventilation through fire-resistant doors, walls and partitions.

• Easy to install.
• For indoor application only

The grids are simply sealed with plaster or silicone in the walls if the available reserve is less than 5mm.

Our Ei fire-resistant ventilation grids are tested according to European standards EN1366-3:2009, EN1364-1:2015 in FprEN1364-5:2017
