Duct Wrap

Jumbolene® DuctWrap is effective thermal insulation made from closed cell polyethylene foam fused with reinforced aluminium foil facing. Its closed cell structure ensures prevention of condensation while offering excellent insulation against heat loss or heat gain.

HVAC (Heating, Ventilation and Air-Conditioning) systems are some of the biggest consumers of energy. Uninsulated or poorly insulated ducts lose through conduction 10% to 30% of the energy used to heat and cool a building. The HVAC system then has to compensate for the heat loss and/or gain by conditioning additional air. This added conditioning raises energy consumption and consequently, the energy bills.

Jumbolene® DuctWrap ensures greater energy efficiency and excellent vibration dampening. The use of Jumbolene® DuctWrap improves the performance of HVAC systems hence increasing the system/machine lifespan.

Ductwrap is ideal for both circular and rectangular ductwork. This solution is recommended for service temperatures of up to 95˚C. The thermal insulation solutions are often applied to air conditioning, warm air and extractor ducts, located in plant rooms or externally.

In addition to its thermal properties, Jumbolag insulation delivers acoustic performance which can be desirable for applications to ducts that carry gases, fluids or particle solids at high velocities. The use of Jumbolag Ductwrap can also significantly improve the level of environmental sound, for a far more pleasant working environment.
