## Summary description

THERMAFLEX FRZ pipe insulation is a high-quality thermal protection solution designed for pipes with a 28mm outer diameter. Featuring a 20mm wall thickness, this insulation effectively minimizes heat loss and prevents condensation. It is suitable for heating and plumbing systems, providing reliable thermal efficiency and durability for professional installation in residential and commercial buildings.

## Long description

The THERMAFLEX FRZ pipe insulation is a professional-grade thermal protection solution engineered for pipes with a 28mm outer diameter. Constructed from high-quality polyethylene foam, this insulation features a 20mm wall thickness, providing an effective barrier against heat loss and condensation. Its robust design ensures consistent thermal efficiency, making it an essential component for maintaining the performance of heating and plumbing systems in both residential and commercial environments.
Advantages
This insulation material offers exceptional thermal properties due to its low thermal conductivity coefficient of 0.035 W/(m·K), which significantly reduces energy waste in pipe networks. The durable polyethylene foam structure maintains its integrity over time, ensuring long-lasting protection. With a density of 40 kg/m³, the material is lightweight yet resilient, allowing for easy handling and installation while providing reliable performance across a wide operating temperature range from -80°C to +95°C.
Suitable for
Heating system pipework
Plumbing and water supply installations
Residential building infrastructure
Commercial HVAC piping systems
When it may not be suitable
This product is not designed for outdoor applications where it will be directly exposed to intense UV radiation or harsh weather conditions without additional protective cladding. It is also not suitable for high-temperature steam pipes that exceed the maximum operating limit of +95°C.
Key specifications
Inner diameter: 28 mm
Wall thickness: 20 mm
Material: Polyethylene foam
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 to be covered and cut the foam tube accordingly using a sharp knife. The tube can be slit longitudinally if the pipe is already installed, or slid over the pipe during the installation process. Ensure that all joints are tightly butted together and secured with appropriate adhesive or tape to maintain a continuous thermal barrier along the entire length of the piping system.
What to consider before purchase
Verify the outer diameter of your pipes matches the 28mm inner diameter of the insulation.
Ensure the 20mm wall thickness meets the specific thermal requirements of your project.
Check that 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 unit is 2 meters long.
Usage recommendations: For optimal results, ensure the pipe surface is clean and dry before applying the insulation. Use professional-grade adhesive tape at all seams to prevent thermal bridging and ensure the insulation remains securely in place.
