THERMAFLEX FRZ Pipe Insulation 42mm Inner Diameter 13mm Wall Thickness

The THERMAFLEX FRZ pipe insulation is a professional-grade thermal protection solution engineered for pipes with a 42mm outer diameter. Manufactured from high-quality polyethylene foam with a density of 40 kg/m³, this insulation provides a reliable barrier against thermal energy loss and environmental factors. With a wall thickness of 13mm, it effectively maintains the temperature of the medium within the pipe, ensuring optimal performance for various plumbing and heating applications.

Advantages

This insulation material offers excellent thermal efficiency due to its low thermal conductivity coefficient of 0.035 W/(m·K). Its flexible structure allows for easy installation around bends and fittings, significantly reducing labor time. By preventing condensation on cold water pipes and minimizing heat dissipation in hot water systems, it contributes to overall energy savings. The durable polyethylene foam construction ensures long-term stability and resistance to mechanical wear, making it a dependable choice for both residential and commercial infrastructure.

Suitable for

• Heating system pipework
• Domestic hot and cold water supply lines
• Preventing condensation on plumbing pipes
• Protection against freezing in temperate environments

When it may not be suitable

This product is not designed for outdoor applications where it would be directly exposed to intense UV radiation or extreme weather conditions without additional protective cladding. It is also not suitable for high-temperature steam pipes or industrial processes exceeding the maximum operating temperature of +95°C.

Key specifications

• Material: Polyethylene foam
• Inner diameter: 42 mm
• Wall thickness: 13 mm
• Length: 2 m
• Thermal conductivity: 0.035 W/(m·K)
• Operating temperature range: -80°C to +95°C
• Material density: 40 kg/m³

How to use

To install the THERMAFLEX FRZ insulation, measure the length of the pipe section 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, which could lead to condensation or heat loss. The flexibility of the material allows it to be easily maneuvered around standard pipe elbows and junctions.

What to consider before purchase

• Verify the outer diameter of your pipes matches the 42mm inner diameter of the insulation.
• Ensure the operating temperature of your system stays within the -80°C to +95°C range.
• Calculate the total length required, keeping in mind that each piece is 2 meters long.
• Consider if additional protective tape or adhesive is needed for your specific installation environment.

Usage recommendations

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