Cold pipe insulation can be installed around drinking and chilled water pipes, as well as air conditioning and outdoor wastewater piping. This helps to prevent water and air being transported at low temperatures from heating up.

ROCKWOOL solutions can help your construction or renovation project maintain a comfortable indoor environment, delivering cool drinking water and air to those living and working inside while increasing energy efficiency.

Our Teclit range has been successfully tested for Eurofins Indoor Air Comfort (Gold) certification – the highest standard available1.

Why do we need cold pipe insulation?

Insulation for cold piping can help to keep pipes that transport cool air and drinking water at their desired low temperature.

When these pipes travel through hot areas of a construction with little or no protection, the contents inside can soon warm up. This is especially true during intense periods of warm weather or in the hottest climates, when they are needed the most. Such temperature increases impair their effectiveness.

By installing effective insulation, less money needs to be spent powering air conditioning, cold water and ventilation in a building, in order to cool down its occupants.

It also helps minimise the carbon footprint of a construction, creating an environmentally friendly way of maintaining a healthy indoor climate.

Calculator and savings

Adding effective insulation around cold pipes can result in significant energy savings – potentially up to and over 50 percent This is because it acts to lower the amount needed to cool businesses, properties and operations, providing a cost-effective way to cut carbon emissions caused by excess cooling2.

To work out the amount and thickness of cold pipe insulation products you will need, we can consult with you to learn what your operation requires.

Our team will look at the operating temperature of the unit it’s being installed around, medium temperatures of the piping and the conditions and temperatures that the pipes operate in.

For our Teclit range, we have also created an easy to use calculator tool for working out the required insulation thickness.

Why choose ROCKWOOL solutions?

Our Teclit System has been specifically designed to insulate cold pipes and hybrid systems, and is:

  • Widely effective – usable in piping with operating temperatures from 0°C up to 250°C, with humidity levels up to 80 percent.
  • Tested to high standards – at the FIW laboratory in Germany.
  • Non-combustible - (A2, s1, d0 RtF according to EN13501-1) for optimal protection in case of fire.
  • Robust – an aluminium laminate creates a high-level vapour barrier (Sd >1.500M).
  • Easy and fast to install – with a mounting time that can be reduced by more than 30 percent compared to conventional non-combustible systems.
  • Dimensionally stable – ensuring no shrinking or expanding.
  • Thermally stable – all ROCKWOOL components will keep the same thermal performance over a period up to 70 years.
  • Aesthetically pleasing – once installed, ROCKWOOL Teclit provides a clean and identifiable look which deserves to be visible.

Teclit components are designed to create the ‘perfect match’ for a complete system. Hangers take care of the piping load and insulation factor, while Teclit Lamella Matts are ideal for insulating large technical units, piping or other elements where a standard pipe section is not the best option.

Teclit LM Cold even comes with a similar high-end aluminium laminate as our pipe sections.

In addition, all of our insulation solutions are:

  • Robust – ROCKWOOL cold pipe insulation remains stable and at peak performance for a lifetime when used, with no shrinking or expanding3.
  • Thermally resilient – the smart fibre structure of stone wool ensures no gaps for passing airflow, maintaining a steady temperature4.
  • Fire resilient – our products are made from fire resilient stone wool, which is non-combustible and protects against fire hazards5/6.
  • Noise reducing – stone wool reduces the impact of noise produced by pipes, making the indoor environment more comfortable, and aiding concentration and productivity7.

Installation

Our products are designed for easy installation, speeding up application time.

Key tips:

  • Gaps and joints in-between sections of insulation can be secured with self-adhesive overlap and special aluminium tape.
  • Lamella and insulated matts, specifically designed for cold pipe insulation, are wrapped around piping and sealed with aluminium tape.
  • When insulation needs to be cut precisely, a long-bladed knife or insulation saw will provide a clean and even cut.
  • For the finishing touches on Teclit products, two high-quality accessories are available. Teclit Flex tape secures a vapour tight shield at penetrations and critical positions. Teclit Alu tape seals off joints at connecting positions – providing great aesthetic value.
