Hot pipe insulation forms an important part of the ROCKWOOL Heating, Ventilation and Air Conditioning (HVAC) range.

Designed to be applied around pipes carrying substances at temperatures between 12°C and 150°C, our products help prevent heat loss during transportation – and can protect against dangerous fire hazards.

Why do we need hot pipe insulation?

Hot pipes are widely used for heating and warm water distribution in large buildings and complexes, such as airports, factories and high-rise residential blocks.

The distances travelled by hot pipes can be long, and the spaces they pass through extremely cold. This is especially true during the autumn or winter months, when the need for them is at its highest.

Insulation acts to keeps the heat inside the pipes while air or water is being transported from the boiler/heating system to central heating units. This helps ensure minimal temperature loss while in transit, and a comfortable indoor atmosphere.

Installing quality hot pipe insulation means less energy is needed to maintain the desired temperature levels. Energy costs can therefore be far lower, particularly during the winter months.

Fire resilient insulation is also essential for fire protection in HVAC systems. Hot piping may run through construction or factory sites that are full of people – or apartment buildings where people sleep. Shielding workers and occupants from the high temperatures inside, and possible fire hazards, is vital.

Calculator and savings

Insulating hot pipes can reduce energy costs by more than 20 percent. This often results in a return on investment within several years of installing.

To help calculate how much insulation you need, and at what thickness, we can work with you to understand the unit you will be insulating.

We can do this by looking at the temperature of the piping when it is in both full and medium operation, as well as the conditions and humidity in the environment where the pipes are. Finally, we’ll consider any additional measurements that need to be factored in around the pipes to come to a final total.

Case studies

The challenge

Groningen Seaports in The Netherlands constructed a 2.7km bio steam pipe, as part of a network of over-ground steam pipelines to send heat generated in plants to nearby businesses.

Keeping heat inside that pipe while in transit, without significant temperature loss, was vital for delivering energy efficient and sustainable heating.

The solution

ProRox ROCKWOOL insulation was used, with 250mm thick stone wool pipe sections. This solution was designed to limit heat loss, largely maintaining the 300°C temperature that it entered the pipeline at (with only a loss of a couple of degrees) and ensuring efficient transportation of heat.

The results

The sustainable solutions installed have ensured a safe supply of energy to local businesses – in an energy efficient way.

Due to the pipe’s layered structure, heat radiation through seams, between pipe sections, is kept to a minimum.

Sustainability and energy efficiency

Heating and cooling in buildings and industry accounts for half of the EU’s energy consumption. Reducing energy demand is therefore extremely important to both cut down energy costs, and minimise the carbon footprint generated by constructions.

We develop solutions that contribute towards this goal.
