Product benefits

Ventilation systems have many different components that work together to ensure a good supply of fresh air. In order for them to operate efficiently, the ducts must be insulated. This is particularly the case for ducts taking in outside air, where insulation outside or inside the duct is used to protect against condensation. With Kaiflex Duct, Kaimann offers a solution with the optimum insulation layer thickness for rectangular ventilation ducts and shafts, which insulates effectively and economically.

Long-lasting performance

Kaiflex Duct delivers reliable long-term insulation performance. The closed-cell foam stands up to the considerable temperature difference between the duct surface and the surrounding air along with the humidity, avoids corrosion and prevents energy losses – for the entire life of the system. Kaiflex Duct also effectively reduces the transmission of unwelcome noises through ventilation equipment.

Its acoustic properties, combined with a fibre-free structure to meet strict hygienic requirements, make Kaiflex Duct ideal for use in public, commercial and industrial buildings.
