URSA AIR ZERO A2 40 mm, are 40mm thick panels made of glass wool used to build rectangular ventilation ducts, thermally and acoustically insulated. The outer surface of the panel consists of aluminum foil reinforced with a dense fiberglass mesh. The interior finish is made of "ZERO" glass fiber fabric, characterized by high durability and resistance to repeated mechanical cleaning. Thanks to the combination of high density mineral wool and special support layers, the product guarantees very high sound absorption and reduces significantly the possibility of bacteria appearing. The material classified as NON-FLAMMABLE ensures a high level of fire safety without affecting the development and spread of the fire.
