Chimney insulation should be a key consideration when manufacturing, installing or renovating flues and chimneys.

Even controlled fires pose serious risks in residential, commercial and industrial settings.

There are three key areas where ROCKWOOL chimney and flue liner insulation can be applied:

  • Domestic – Homes with chimney systems often use coal, wood or oil as fuel sources. These systems require effective insulation to protect occupants.
  • OEMs (ROCKWOOL Core Solutions)An efficient way to improve the safety of steel or ceramic chimneys and fireplaces is to install quality insulation products at the point of manufacture. Core Solutions specialists can provide product-enhancing consultative partnerships in this area.
  • ROCKWOOL Technical InsulationFire resilient insulation for industrial chimneys can safeguard workers and the environment.

Effective thermal regulation also acts to improve energy efficiency in all cases.

Whether you’re a homeowner, property developer, manufacturer or business owner, ensuring safe and efficient working chimneys is essential.

Why do we need chimney insulation?

There are more than 25,000 chimney fires each year in the USA alone1These can cause extensive, costly structural damage – and endanger the lives of people living and working in the affected buildings.

When burning certain fuels in chimneys, flue gases are produced. If the flue gas reaches a higher temperature than those allowed for by the chimney design – or if the chimney cools and causes a build-up of residue – it can result in a fire2.

Our flue liner insulation can help regulate temperatures to avoid over-heating, or sudden cooling that could lead to flammable residue build-up3.

The use of stone wool insulation as an intermediate layer also prevents heat from being transferred to the outer surfaces – again, raising safety for those nearby.

Key benefits of installing quality insulation in chimneys can also include:

  • Acoustic blocking
  • Energy efficiency

Calculator and savings

The use of stone wool insulation can lead to significant heating, energy and cost savings in chimneys across a range of applications.

Whether in the home or industrial settings, this can lead to more comfortable temperatures, lower energy bills, and a safer environment that drastically reduces the risk of expensive fire damage.

The amount of insulation required, and the exact savings it could make, will depend on the size and shape of the chimney in question.

The question of whether you are installing insulation in a new chimney, at the point of manufacture, or while renovating an existing one, can also affect the products required and the performance expected. Our local experts are happy to help with any queries you may have.
