It is a black glass wool blanket faced with acrylen on one side. It is used for the sound insulation, thermal insulation and fire safety of ventilating and air conditioning ducts.
Before Izocam Acoustic is applied, duct surfaces to be used are cleaned to make sure the surface is free from dust and grease. The duct to be insulated should be measured inside to inside. Attention should be paid to the insulation thickness and Izocam Acoustic should be cut in accordance with the measurement. Self adhesive fixing pins are placed into the duct according to the air flow velocity. Izocam acoustic adhesive is spread over the duct surface by the help of a brush and the boards cut to be used are laid over. All transverse and longitudinal joints should be sealed to ensure they fit properly and no gap is left. Lock washers should be put over pins. Lenght of pins should assure minimum 10 % compression of insulation thickness. Excess ends of the pins should be snipped off.
