• Ventilation Grids

    Ventilation grids are installed at the end of a ventilation system to prevent vermins from entering the ventilation tube or birds from building a nest inside the tube. Ventilation grids are used for air inlets same as for outlets.

    Ther are coarse meshed grids on the market for bigger vermins (mice, rats, martens etc) and fine meshed grids for smaller vermins (like insects) and of course a combination of both. Ventilation grids are made of plastic or made of metal. Mostly common is the round form but there are some manufacturers that produce rectangled ones.
