insulation of steel ventialion duct

Indoor temperature has a significant impact on the comfort and performance of a building’s occupants, whether in a commercial, residential or leisure environment.

Modern HVAC (heating, ventilation and air conditioning) units control the interior climate – and effective, high-quality duct insulation helps maintain desired airflow temperature throughout the building.

As the air in the ducts travels throughout the complete building, it passes many levels without heating or cooling available, causing an unwanted temperature rise or drop.

Quality insulation products prevent energy loss should cold air start to heat up, or hot air begin to cool down, when travelling from the unit to its destination. They help retain indoor comfort, without using excess energy to reheat or cool the air.

Why do we need ventilation duct insulation?

HVAC units are designed to maximise comfort in large, modern constructions, including:

  • Industrial – energy plants, warehouses, data centres and other buildings where ventilation units are installed
  • Commercial – sports centres, offices and leisure
  • Residential – apartment blocks
  • Essential services – hospitals and airports

This can require a great deal of energy. But effective use of insulation results in lower consumption levels, leading to a more cost-efficient and environmentally sustainable constructions1.

Our duct insulation products can be used for rectangular and circular ventilation ducts operating within a temperature range of 12°C to 250°C, or 0°C for Teclit Lamella Matts. They reduce the energy required to keep hot and cold air flowing at the optimum temperature.

As ducts are spread throughout buildings and transport hot air, this can also pose a fire risk. Insulating ventilation ducts with fire resilient stone wool improves fire safety.

Calculator and savings

Insulation of ventilation ducts can lead to significant savings.

Generally, insulating HVAC applications can deliver a return on investment within three years – helping create a far more cost-efficient building.

The amount of insulation required depends on the size and shape of your ventilation ducts, the ideal temperature and other environmental factors. Speak to one of our experts at your local ROCKWOOL office for personalised help and advice.
