HVAC Insulation

HVAC insulation can be used in these systems across large-scale commercial and residential properties, including high-rise offices, apartment blocks, airports, hospitals, warehouse and other industrial facilities, ensuring a comfortable living environment.

Effective insulation is essential for maintaining the correct operating temperature for the different parts of a system – from piping to air conditioning insulation. As these properties use a lot of energy to create a comfortable climate, working as efficiently as possible is vital.

Why do we need HVAC insulation?

Insulating HVAC systems improves efficiency, reduces carbon emissions and cuts operating costs. It helps keep indoor temperatures stable with minimum energy consumption – forming a comfortable living environment for workers and occupants.

In addition, heating and cooling systems in large buildings can be incredibly loud, so insulating them also improves acoustic performance – and reduces disturbance from unwanted noise as well.

Meanwhile, the excess heat they produce could pose a fire risk, so proper insulation adds another layer of vital protection.

HVAC insulation can be applied to new buildings and renovations. In many countries, it can ensure engineering companies, architects, contractors and installers remain compliant with local energy and safety standards.

Key benefits of ROCKWOOL applications include:

Improved energy efficiency
Reduced noise pollution
Fire protection

Calculator and savings

According to research, insulating cold pipes can lead to energy savings of up to 50 percent, while for hot pipes savings can go up to 20 percent This reduces operating costs and energy consumption, presenting a return on investment – usually within three years.

The optimal insulation thickness is determined by the operating temperature of the HVAC unit, median temperature of the piping or duct, environmental conditions and any additional measurements (such as Legionella prevention or desired energy performance).

Why choose ROCKWOOL solutions?

ROCKWOOL insulation is designed to last the lifetime of a building and maintain the same high standard of performance throughout.

We offer a wide range of HVAC insulation products to suit different systems – from aluminium laminate faced pipe sections, to lamella matts for ventilation ducts.

Using the power of stone wool, each one improves the energy efficiency, fire safety and acoustic performance (where relevant) of the heating, cooling, piping or ventilation system.

Benefits of ROCKWOOL solutions include¹:

Energy efficiency
Fire resilience
Acoustic capabilities
Thermal properties
Circularity

ROCKWOOL HVAC products do not shrink or wear out under the influence of temperature changes, and maintain the same performance. We deliver a full range of solutions at all required thicknesses and dimensions.

Our insulation products improve energy efficiency, keeping temperatures comfortable and stable with a minimum of energy usage. This not only reduces costs, but also helps protect our climate – and is a very efficient investment for the future.

Hot Pipe Insulation | ROCKWOOL

Quality hot pipe insulation can prevent heat loss in HVAC systems and offer fire protection for piping at high temperatures.

Installation

To ensure proper and correct installation, we can deliver an installation manual, on-site training, education and easy-to-access guidance such as additional installation brochures on the web.

Insulation can be installed on many types of piping, with the thickness determined by its operating temperature range. Use the self-adhesive overlap and special aluminium tape to seal the joints securely.

With air conditioning insulation, lamella and insulated mats are wrapped around the ventilation ducts and pipes. Special aluminium tape should be used to seal the joints.

Key tips²:

Securely seal insulation – Follow the supplied guidelines and use aluminium tape to secure seals and avoid gaps.
Use a registered installer – Our professional training and education means they can assess the building, recommend the best HVAC insulation types to use, and install it correctly.
Determine insulation material required – Work out the density needed to protect hot or cold pipes (up to 100kg/m3) and for ventilation ducts (up to 50kg/m3).

Sustainability and energy efficiency

All ROCKWOOL HVAC insulation material is fully recyclable – whether it’s for piping, air conditioning or heating systems. Our products can be easily removed from a building if it is being demolished and recycled back into new products, preventing a significant amount of landfill³.

Our piping, heating and air conditioning insulation can be installed without the use of toxic adhesives or other chemical components that harm the environment.

ROCKWOOL insulation also reduces the energy consumption used to power large buildings, including apartment blocks. The additional benefit of acoustic absorption reduces noise pollution, further ensuring stable and comfortable environments for work and living⁴.
