THERMAFLEX FRZ Pipe Insulation 48mm Inner Diameter 13mm Wall Thickness

The THERMAFLEX FRZ pipe insulation is a professional-grade polyethylene foam sleeve engineered to provide superior thermal protection for various piping systems. With an inner diameter of 48 mm and a wall thickness of 13 mm, this insulation is specifically designed to minimize heat loss and prevent the formation of condensation on pipe surfaces. Its robust structure makes it a reliable choice for maintaining the efficiency of heating and plumbing installations in both residential and commercial environments.

Advantages

This insulation material offers excellent thermal performance due to its low thermal conductivity coefficient of 0.035 W/(m·K), which helps maintain stable temperatures within the pipes. The high-density polyethylene foam, rated at 40 kg/m³, provides a durable barrier that resists mechanical wear and environmental factors. Its wide operating temperature range from -80°C to +95°C ensures versatility across diverse climate conditions and system requirements, effectively protecting pipes from freezing and energy waste.

Suitable for

• Heating system piping
• Plumbing and water supply lines
• Residential building infrastructure
• Commercial HVAC installations

When it may not be suitable

This product is not equipped with an integrated aluminium foil layer, so it should not be used in applications where high-reflectivity or additional vapor barrier protection is required. It is also not intended for outdoor exposure to direct, prolonged UV radiation without additional protective covering.

Key specifications

• Inner diameter: 48 mm
• Wall thickness: 13 mm
• Material: Polyethylene foam
• Length: 2 m
• Density: 40 kg/m³
• Thermal conductivity: 0.035 W/(m·K)
• Operating temperature range: -80°C to +95°C

How to use

The insulation sleeve is designed for easy installation on existing or new piping. Simply slide the foam tube over the pipe section. For longer runs, ensure that the joints between individual segments are tightly fitted and secured to prevent thermal bridging. The material can be easily cut to the required length using a sharp utility knife to ensure a precise fit around valves or bends.

What to consider before purchase

• Verify the outer diameter of your pipes matches the 48 mm inner diameter of the insulation.
• Ensure the 13 mm wall thickness meets the specific thermal requirements of your project.
• Check if the installation environment requires additional UV protection or moisture barriers.

Usage recommendations

For optimal thermal efficiency, ensure all seams are properly sealed and that the insulation fits snugly against the pipe surface without gaps. Avoid stretching the material during installation to maintain its structural integrity and insulating properties.
