Temperature maintenance is one of the most significant factors that influence comfort of occupants in the building, therefore a large amount of energy is wasted to maintain chosen temperature - air conditioning and ventilation equipment. Although heat loss is unavoidable, using adequate thermal insulation of ventilation ducts can reduce energy consumption. In order to calculate thermal insulation thickness, we recommend checking International standard ISO 12241 ‘Thermal insulation for building equipment and industrial installations. Calculation rules’.
Ducts and fittings (bends, t-pieces, reducers, dampers and couplings) are available with 25, 50 and 100 mm insulation.
