Pipe Insulation

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 cause.

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

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 with minimum energy usage.

The fire resilience properties of our stone wool insulation are also important – especially for hot pipes – as they can run throughout a building at high temperatures.

Acoustic absorption also limits the impact from sometimes-noisy pipes and HVAC systems on building occupants, minimising daily disruption.

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.

Insulation thickness is determined by the:

Temperature range at which the HVAC unit operates.
Medium temperature of the piping or duct.
Additional measurements to take into the calculation
Environment conditions (humidity in % and temp in °C).

Applications

Insulation

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

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

slab and insulated matts are wrapped around the pipes, with the joints sealed by use of special aluminium tape.

Key tips⁵:

Use a registered installer – best performance is achieved through proper installation by a certified expert.
Seal insulation gaps – use special aluminium tape to avoid heat loss through unwanted gaps.

Sustainability and energy efficiency

We achieve results through the use of stone wool, which means all our pipe products are fully recyclable. They can be removed from a building at the end of its life and used again – providing circularity and preventing landfill⁶.
