Insulation for ductwork helps to minimise heat loss and create more thermally efficient HVAC systems.

Ductwork insulation is crucial for your HVAC system helping to preserve the temperature of the conditioned air flowing through the system. This can lead to increased energy efficiency and maintaining overall indoor comfort.

Ductwork insulation helps create stable temperatures

When ducts run through unconditioned areas (such as attics, basements, or garages), they can be exposed to significant temperature fluctuations. Without proper insulation, HVAC systems can lose heat to cold surroundings in winter and absorb unwanted heat during summer, reducing overall efficiency and increasing energy consumption.

Take a closer look at the benefits of ductwork insulation

Made from glass mineral wool, Isover Climcover ductwork insulation can help to reduce heat loss and create more thermally efficient HVAC systems. Let’s look at the core elements.

Heat loss protection

Glass wool insulation owes its thermal performance to air pockets trapped within its fibre structure. When used to insulate ductwork, this insulation helps to significantly reduce heat transfer and heat gain, helping to minimize energy loss, maintain stable internal temperatures and enhance the overall efficiency of HVAC systems.
