Phenolic Pipe Section (Steel) – 17mm to 610mm (1m Lengths)

Phenolic Pipe Section for Steel Pipework – 17mm to 610mm (Pipe section length 1 metre)

Phenolic Pipe Section for steel pipework is a high performance thermal insulation solution designed for commercial, industrial and mechanical service installations where space, energy efficiency and reliable condensation control matter. Manufactured from rigid phenolic foam with a factory applied aluminium foil facing, it provides excellent thermal performance in a compact profile, helping reduce heat loss, control surface temperature and improve the efficiency of hot and cold pipework systems.

Why choose Phenolic Pipe Section?

Excellent thermal performance – helps reduce heat transfer and improve system efficiency

Space saving insulation – ideal for congested plant rooms, service risers and ceiling voids

Foil vapour barrier facing – supports condensation control on chilled and cold water services

Rigid and lightweight – easy to cut, handle and install around steel pipework

Strong fire and smoke performance – suitable for projects where fire performance is a key consideration

Wide steel pipe size range – available for pipe outside diameters from 17mm to 610mm

Typical applications

• Steel pipe insulation in commercial buildings

• Heating and chilled water pipework

• HVAC and mechanical service installations

• Plant rooms, risers and service corridors

• Process pipework and energy efficient building systems

• Projects where reduced insulation thickness is required

Product overview

This phenolic pipe insulation section is designed to deliver high levels of thermal resistance without adding unnecessary bulk. Its rigid structure helps maintain shape during installation, while the foil facing provides a neat finish and assists with vapour control when joints are correctly sealed. It is particularly useful on steel pipework where insulation depth, energy performance and long term reliability are important.

Key benefits

Improved energy efficiency – reduces unwanted heat loss or heat gain through pipework

Condensation control – supports cold and chilled water systems when installed with sealed joints

Lower running costs – helps reduce wasted energy across heating and cooling systems

Cleaner installation – preformed sections are easier to install than loose insulation materials

Durable system finish – rigid phenolic foam resists compression better than many softer insulation types

Installation guidance

• Select the correct section size for the steel pipe outside diameter.

• Ensure pipework is clean, dry and free from loose debris before fitting.

• Fit the preformed phenolic section tightly around the pipework with joints neatly aligned.

• Seal longitudinal and circumferential joints with suitable foil tape to maintain vapour barrier continuity.

• Use appropriate bands, ties or mechanical fixings where required by the project specification.

• Apply additional protective cladding in areas exposed to impact, weather or hygiene requirements.

Recommended with this product
