THERMAFLEX FRZ Pipe Insulation 89/13

The THERMAFLEX FRZ 89/13 is a professional-grade pipe insulation solution engineered for the thermal management of heating and plumbing systems. Constructed from high-quality closed-cell polyethylene foam, this insulation provides an effective barrier against heat loss and condensation buildup. With an inner diameter of 89 mm and a wall thickness of 13 mm, it is designed to fit standard piping systems securely, ensuring consistent thermal performance across residential and commercial installations.

Advantages

The primary benefit of this insulation is its excellent thermal efficiency, characterized by a low thermal conductivity coefficient of 0.035 W/(m·K). The flexible nature of the polyethylene foam allows for quick and easy installation, even in tight spaces or around complex pipe bends. Its durable structure maintains its integrity over time, providing long-term protection for piping infrastructure. Furthermore, the material is resistant to moisture, which significantly helps in preventing corrosion and the formation of condensation on cold water pipes.

Suitable for

• Thermal insulation of heating system pipes
• Protection of hot and cold water supply lines
• Preventing condensation on plumbing installations
• Residential and commercial building infrastructure

When it may not be suitable

This product is not designed for use in environments where pipes are exposed to direct sunlight or extreme UV radiation, as the material may degrade over time. It is also not intended for high-temperature industrial steam lines that exceed the maximum operating temperature of +95°C.

Key specifications

• Material: Polyethylene foam
• Inner diameter: 89 mm
• Wall thickness: 13 mm
• Length: 2 m
• Density: 40 kg/m³
• Thermal conductivity: 0.035 W/(m·K)
• Operating temperature range: -80 to +95°C

How to use

To install the THERMAFLEX FRZ 89/13, measure the length of the pipe section to be insulated and cut the foam tube to the required size using a sharp knife. If the insulation is not pre-slit, cut it longitudinally along the side. Wrap the insulation around the pipe, ensuring a snug fit. For optimal performance, seal all joints and seams with appropriate adhesive tape to prevent air gaps and moisture ingress.

What to consider before purchase

• Verify the outer diameter of your pipes matches the 89 mm inner diameter of the insulation.
• Ensure the operating temperature of your system remains within the -80 to +95°C range.
• Calculate the total length required, keeping in mind that each unit is 2 meters long.

Usage recommendations

For the best results, ensure that the pipe surface is clean, dry, and free of dust or grease before applying the insulation. Properly sealing all joints is critical to maintaining the thermal efficiency of the system.
