Ventilation Duct Insulation

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 ventilation ducts operating within a temperature range of 12°C to 250°C,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.

Why choose ROCKWOOL solutions?

Our products are available to suit almost every kind of building and HVAC system. This includes aluminium faced products.

Stone wool is dimensionally stable – meaning our products don’t shrink or wear out under the influence of extreme temperatures. This means they maintain the same performance throughout the building’s lifetime. In addition, no joints are created by shrinking insulation over time, which could otherwise lead to thermal losses and inefficient operating units.

Due to the natural properties of stone wool, additional fire resilience and acoustic absorption properties help create a quieter and safer environment too.

Benefits of ROCKWOOL solutions include²:

Fire resilience
Temperature maintenance
Acoustic blocking
Thermal properties
Circularity

Due to optimal co-operation with production departments, we can guarantee the highest quality available. We understand our clients and markets and know which performance and requirements must be met.

Applications

Insulation

Pipe Insulation | ROCKWOOL

Pipe insulation can keep warm and cold water at its optimum temperature when transported through HVAC systems.

Installation

Key tips³:

Use a professional installer – professional training helps ensure the best installation to help your HVAC systems operate as efficiently as possible.
Choose the right product – duct insulation can be applied to rectangular and circular ducts, with varying thicknesses for different requirements.
Remember fire safety – if the ventilation duct must be insulated and also perform a certain level of fire resistance, have a look at our engineered, developed and tested solutions for fire rated ducts.

Sustainability and energy efficiency

Our products are fully recyclable and can easily be removed and recycled or reused when a building reaches the end of its life. This prevents excess landfill⁴.
