Thermaflex Polyethylene Pipe Insulation 18 mm x 9 mm

Thermaflex polyethylene pipe insulation is a professional-grade thermal protection solution engineered for pipes with an 18 mm diameter and a 9 mm wall thickness. This flexible foam material is designed to minimize heat loss in heating systems and prevent condensation buildup in plumbing installations. By maintaining consistent pipe temperatures, it enhances the overall energy efficiency of residential and commercial infrastructure while providing a robust barrier against environmental factors.

Advantages

The primary benefit of this insulation is its high-quality polyethylene foam structure, which offers excellent thermal resistance and flexibility for easy installation around bends and fittings. Its closed-cell composition effectively repels moisture, preventing the formation of condensation that can lead to corrosion or water damage. Furthermore, the material is lightweight and durable, ensuring reliable performance over an extended service life while contributing to reduced energy consumption in building climate control systems.

Suitable for

• Heating system pipework
• Domestic hot and cold water plumbing
• Preventing condensation on cold water lines
• Reducing thermal energy loss in residential buildings

This insulation may not be suitable for high-temperature applications exceeding the thermal limits of polyethylene foam, such as direct contact with steam pipes or industrial high-heat exhaust systems. It is also not intended for outdoor use where it would be continuously exposed to direct UV radiation without additional protective cladding.

Key specifications

• Material: Polyethylene foam
• Inner diameter: 9 mm
• Wall thickness: 9 mm
• Pipe diameter compatibility: 18 mm
• Length per unit: 2 m

To install the insulation, measure the length of the pipe section and cut the foam tube to the required size using a sharp utility knife. If the pipe is already installed, use the pre-slit opening to wrap the insulation around the pipe. Ensure all seams are tightly joined and secured with appropriate adhesive or tape to maintain a continuous thermal barrier. For elbows or T-junctions, miter-cut the foam at 45-degree angles to ensure a snug fit.

What to consider before purchase

• Verify the outer diameter of your pipes to ensure a correct fit
• Calculate the total linear meters required for your project
• Ensure you have compatible adhesive or insulation tape for sealing joints

For optimal performance, ensure that all joints and seams are completely sealed to prevent air gaps. Regularly inspect the insulation for any signs of mechanical damage to maintain its thermal efficiency.
