The Ubbink Insulated ISO Duct Sleeve is a insulated solution designed for ventilation and air supply systems. Each sleeve features a durable aluminium laminate outer jacket combined with a glass wool insulation layer, providing effective thermal and acoustic performance.

With a 25mm insulation thickness, the ISO Duct Sleeve helps prevent condensation while minimising heat loss and cold loss within the ductwork. It also absorbs and reduces sound transmitted through ventilation systems, contributing to improved indoor comfort in residential and light commercial buildings.

Supplied in 10-metre rolls, the sleeve is easy to fit and install over a wide range of duct diameters, making it a practical choice for both new installations and retrofit projects. It also complies with relevant UK fire performance standards, offering added peace of mind.
