Install ROCKWOOL’s pipe insulation around chilled and low-temperature water pipes, as well as wastewater soil vent pipes.
Pipe lagging helps prevent condensation, slows down freezing of pipe contents when temperatures drop and can prevent water being transported at low temperatures from heating up.
Our pipe insulation products are suitable for both domestic and commercial use, whether you are working on a retrofit project or a new construction.

We all know that cold pipe insulation offers a range of benefits.
As well as keeping pipes that transport water at a low temperature, ensuring a consistent and reliable supply of cold water, stone wool pipe lagging can:
BS 5422:2023 guides designers, specifiers, contractors, and manufacturers of thermal insulation, helping them determine the minimum insulation thickness required to control and reduce heat loss and gains from building services. It also covers the importance of insulating pipes and ductwork to maintain the integrity of compartmentation in fire stopping.
Architects and specifiers face a significant challenge keeping up with ever-evolving regulations and guidance documents to ensure full compliance and construct buildings that withstand the test of time.
However, we’re here to help and support you with CPD learning modules and advice from our team of experts to help you specify the right product to comply with the regulations, as and when they change.

Refer to and use BS 5422 to meet the requirements outlined in the following guidance:
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.
| Issues to consider | Why ROCKWOOL is the right solution |
| Thermal performance | ROCKWOOL products will keep the same thermal performance over the lifetime of a building. |
| Acoustic performance | We make our products from stone wool, which absorbs sound and reduces the impact of noise produced by pipes. |
| Fire performance | Our HVAC insulation products are made from non combustible stone wool (A1 or A2, s1, d0 RtF according to EN13501-1) which are the highest two Euroclass ratings (see table). |
| Durability | ROCKWOOL products are dimensionally stable and maintain the same thermal performance for the lifetime of the building. |
| Suitability |
Our pipework insulation products are suitable for use in piping with operating temperatures from 0°C up to 250°C. An aluminium laminate creates a high-level vapour barrier (Sd >1.500M). |
| Water repellent | ROCKWOOL Stone wool does not absorb moisture when exposed to water. Stone wool is water-repellent, meaning it resists water absorption. |
Our products are designed for easy installation, speeding up application time.
