Prevent this heat radiation with this Tonzon bandage foil. The bandage foil is 25 meters by 15 cm. You wrap it around the insulated pipe to immediately stop the heat loss. Sometimes sections are not or not properly insulated. This is often the case at corners and T-junctions and near a valve. Heat radiation is even greater in these areas. Bandage foil can significantly reduce this loss. Tonzon HR Bandage Foil can be used anywhere where limiting heat radiation is needed. For example, in central heating pipes, hot water pipes, air heating ducts, etc. So also in a convector pit and in the cupboard where the district heating heat exchanger is located, HR bandage foil can be used.
