Similar to Sonolight AD-L, the ALSDL-PE-L duct is based on Aluduct and provides thermal and acoustic insulation for mechanical ventilation and heat recovery systems. The inner duct, made of aluminum-polyester foil, is reinforced with a spiral steel wire, giving it the necessary shape. A key feature is the vapor barrier foil placed between the inner duct and the mineral wool insulation. This prevents condensation from penetrating the wool due to temperature differences, thus preserving the insulation's acoustic and thermal properties.
