Pipe Insulation

Find products Resources Cold pipes Hot pipes

High-quality pipe insulation in HVAC systems maintains the optimum temperature of fluids or gasses transported around a building or facility.

As hot or cold water has quite a long way to travel throughout a building, it is crucial it maintains its required temperature as much as possible. During this process, it passes many spaces where additional heating or cooling is unavailable, meaning non-insulated pipes can heat up or cool down – with all the negative consequences that can occur as a result of poorly insulated or un-insulated services.

Pipes require different performance levels to keep water hot or cold:

Warm water – insulation prevents heat loss, saving energy when water travels between a boiler or heating system to central heating units.
Cold water – insulation keeps the temperature low and can protect against condensation, ensuring it is delivered at its required temperature.
Rain/waste water – cold water pipe insulation prevents the formation of condensation which can cause corrosion or damage to the surrounding structure and can also reduce unwanted noise.

Effective insulation means HVAC systems don’t have to work as hard to maintain the operating temperature of the unit, thereby reducing energy consumption.

Pipe Section Mat (PSM)

High and mighty. Insulating heating, ventilation and air-conditioning pipes prevents them from altering the temperature of any rooms or compartments they pass through. Pipe Section Mat (PSM) has been designed for HVAC application above 406mm diameter.

RockLap H&V Pipe Sections

In it for the long run. Insulation of pipework through buildings prevents the pipe temperature transferring to any environments they pass through. In working environments, it is important to keep temperatures comfortable and stable. High temperatures from pipework can also pose a fire risk, but RockLap H&V Sections offer an excellent pipe insulation solution.

Why do we need pipe insulation?

Heating and cooling buildings accounts for around half of all energy consumption¹. Reducing the required energy demand can cut both operating costs and carbon emissions for many large constructions – such as airports, apartment blocks, warehouses and schools.

HVAC pipe insulation improves the operating efficiency of heating and cooling units to keep temperatures comfortable and stable with minimum energy usage.

The fire resilience properties of our stone wool insulation are also important – especially for hot pipes – as metal pipework can act as heat conductors which can lead to fire spreading through to other compartments.

Acoustic absorption also limits the impact from noise transfer through HVAC pipework and services on building occupants, minimising daily disruption and creating a comfortable working and living environment.

Calculator and savings

Applying insulation for cold pipes can lead to energy savings of up to 50 percent, while insulation for hot piping can result in energy savings up to 20 percent²^. There can be differences between countries, but in general pipe insulation can create a return on investment within three years.

Our aluminium faced pipe insulation solutions are designed for HVAC services operating within a temperature range of 0-250ºC.

Insulation thickness is determined by the:

Requirements of HVAC solution e.g. personnel protection, condensation control, heat loss.
Operating temperature of the piping or duct.
Dimensions of the service to be insulated
Environmental conditions (humidity in % and temp in °C).

Case studies

The challenge⁴

Amager Bakke is an innovative energy-from-waste plant in Copenhagen, Denmark. It turns waste from around 700,000 households into electricity and heating. It also doubles as a leisure facility (with ski slope and climbing wall), as the builders were so confident of its green credentials.

However, to further reduce its emissions and create a safe working and leisure environment, it required high-performance insulation.

The solution

To achieve high energy efficiency levels, while also protecting workers and local residents from any risk of fire, ROCKWOOL insulation was installed around pipes and elsewhere within the facility.

The results

The properties of stone wool are helping the plant achieve its high environmental goals – improving the plant’s thermal efficiency, protecting workers from heat, and enhancing fire protection.

Installation

Our products can be installed onto various types of piping, with the thickness based on the temperature range of the operating unit.

Preformed pipe sections are manufactured to suit various standard steel pipe diameters, offering ease of installation. All joints to be sealed using an aluminium foil tape to maintain the vapour barrier.

To assist correct installation of specific products, guidance is offered within the relevant installation guide. We can also offer Technical Support and education through CPD's where relevant.

Key tips ⁵:

Use a registered installer – best performance is achieved through proper installation by a certified expert.
Refer to product data sheet and installation guidelines -- for the best guidance on effectively insulating pipes, consult the supplied instructions before installation.
Seal insulation gaps – use aluminium foil tape to avoid heat loss through unwanted gaps and to maintain the vapour barrier where required.
