Pipe Insulation & Lagging for Heating, Plumbing & HVAC
Explore our range of pipe insulation and pipe lagging for domestic plumbing, heating systems, commercial building services and industrial pipework.
We supply mineral wool, fibreglass, rubber and phenolic pipe insulation from established manufacturers including ROCKWOOL, PAROC, ISOVER, Kaimann, Armacell and Kingspan.
Whether you need insulation for hot water pipes, chilled water systems, heating installations or exposed pipework, browse the materials below to find the appropriate product for your project.
Choose Your Pipe Insulation Type
Different pipe insulation materials provide different thermal, moisture-control and fire-performance properties. Select the material suitable for your application.
Mineral Wool Pipe Insulation
Rigid and semi-rigid stone wool pipe sections from ROCKWOOL and PAROC. Commonly used for hot water, heating, mechanical services and industrial pipework where thermal performance and non-combustible insulation may be required.
Shop Mineral Wool Insulation →Fibreglass Pipe Insulation
Foil-faced glass wool pipe sections from ISOVER for suitable heating, hot water and mechanical services. A practical option for commercial and industrial pipe insulation installations.
Shop Fibreglass Insulation →Rubber Pipe Insulation
Flexible elastomeric insulation from Kaiflex and Armacell for appropriate chilled water, air-conditioning, refrigeration and heating applications. Closed-cell construction helps control moisture vapour ingress when correctly installed.
Shop Rubber Pipe Insulation →Phenolic Pipe Insulation
Rigid phenolic foam pipe sections, including Kingspan Kooltherm and Supafen ranges. Provides low thermal conductivity and can be particularly useful where insulation space is limited.
Shop Phenolic Insulation →Which Pipe Insulation Should You Choose?
| Material | Typical Applications | Key Consideration |
|---|---|---|
| Mineral Wool | Heating, hot water, plant rooms and industrial services | Thermal and fire performance |
| Fibreglass | Heating and mechanical pipework | Thermal insulation with suitable facing |
| Rubber | Chilled water, refrigeration and HVAC | Condensation and vapour control |
| Phenolic | Heating and commercial pipework | High thermal resistance in limited space |
This is a general selection guide. Always check the manufacturer's datasheet for temperature limits, fire classification, vapour resistance and application suitability.
How to Choose the Correct Pipe Lagging Size
When selecting pipe insulation, check these three measurements and requirements:
1. Pipe diameter: Match the insulation's internal bore to the actual outside diameter of your pipe. Nominal pipe sizes and outside diameters are not always the same.
2. Insulation thickness: Choose the required wall thickness according to the service temperature, location and project specification. BS 5422 and relevant Building Regulations may apply.
3. Location and protection: External pipework, chilled systems and high-temperature installations may require specific insulation materials, vapour barriers, protective cladding or trace heating.

Pipe Insulation Accessories & Protection
Depending on the application, your installation may also require tapes, fixings, protective coverings or frost-protection products.

Mineral wool, fibreglass, phenolic and suitable elastomeric insulation can all be used for heating pipework. The correct choice depends on operating temperature, available space, fire requirements and required insulation thickness.
Closed-cell rubber insulation is commonly used for chilled water and refrigeration systems because it provides thermal insulation and resistance to water vapour ingress. Correct joint sealing and thickness are essential for condensation control.
Required thickness depends on pipe diameter, service temperature, operating conditions and the applicable building or project specification. Refer to the relevant manufacturer's technical information and BS 5422 guidance.
Insulation slows heat loss but cannot guarantee that a stationary water-filled pipe will not freeze during prolonged cold conditions. Exposed or vulnerable pipework may require a correctly designed trace heating system together with suitable insulation.
Yes, provided the insulation system is suitable for the operating and environmental conditions. Some materials require weatherproof cladding or other protection from moisture, sunlight and physical damage.
