THERMAFLEX FRZ Pipe Insulation 48/20

The THERMAFLEX FRZ pipe insulation 48/20 is a professional-grade thermal protection solution engineered for pipes with a 48 mm diameter. Constructed from high-quality polyethylene foam with a wall thickness of 20 mm, this insulation provides an effective barrier against thermal energy loss and moisture accumulation. Its flexible design allows for easy installation on various piping systems, ensuring consistent performance in both residential and commercial environments.

Advantages

This insulation material offers excellent thermal efficiency due to its low thermal conductivity, which helps maintain stable temperatures within the pipes. The closed-cell structure of the polyethylene foam provides robust resistance to water vapor, effectively preventing condensation and protecting the underlying pipework from corrosion. Its flexibility simplifies the installation process, even in tight spaces or around bends, while the durable material composition ensures long-lasting reliability and consistent energy savings over time.

Suitable for

• Plumbing systems in residential buildings
• Heating and hot water distribution networks
• Commercial HVAC piping installations
• Preventing condensation on cold water pipes

This product may not be suitable for outdoor applications where it will be directly exposed to intense ultraviolet radiation or harsh weather conditions without additional protective cladding. It is also not intended for use on high-temperature steam lines or industrial processes that exceed the maximum operating temperature limit of 95°C.

Key specifications

• Material: Polyethylene foam
• Inner diameter: 48 mm
• Wall thickness: 20 mm
• Length: 2 m
• Thermal conductivity: 0.035 W/(m·K)
• Density: 40 kg/m³
• Operating temperature range: -80°C to +95°C

How to use

To install the THERMAFLEX FRZ insulation, measure the length of the pipe section to be covered and cut the foam tube accordingly using a sharp knife. If the pipe is already installed, the insulation can be slit longitudinally, placed around the pipe, and secured using appropriate adhesive or tape. Ensure that all joints are tightly sealed to prevent air gaps, as these can lead to condensation and reduced thermal efficiency. The material is lightweight and easy to handle, allowing for quick application on straight runs and standard pipe configurations.

What to consider before purchase

• Verify the outer diameter of your pipe matches the 48 mm inner diameter of the insulation.
• Check if the 20 mm wall thickness meets the specific thermal insulation requirements for your project.
• Ensure the operating temperature of your system remains within the -80°C to +95°C range.
• Consider the total length of piping to calculate the required number of 2-meter segments.

Usage recommendations

For optimal energy efficiency, ensure that all seams and butt joints are fully sealed with compatible insulation tape. Avoid stretching the material during installation to maintain the integrity of the foam structure and its thermal properties.
