AERONEIGE 1 is a snow guard that prevents snow that has accumulated on the roof from suddenly falling off.AERONEIGE 1 can be used to retain the snow on the roof to keep the thermal insulation provided by the layer of snow, limiting the extent of daily temperature variations on the surface, which very often cause ice sheets to form as a result of this alternating freezing/thawing.AERONEIGE 1 also limits thermal heat loss from the home by insulating the roof from extreme air and wind temperatures using the thickness of the snow.AERONEIGE 1 retains the snow on the roof and stops it from falling onto the ground, preventing it from injuring a passer-by or from blocking a door to the home or traffic on the pavement.
