## Summary description

THERMAFLEX FRZ pipe insulation is a high-quality polyethylene foam sleeve designed for thermal protection of heating and plumbing pipes. With an 18mm inner diameter and 13mm wall thickness, it effectively reduces heat loss and prevents condensation. Suitable for professional installation in residential and commercial systems, this durable insulation ensures energy efficiency and long-term performance in various piping applications.

## Long description

The THERMAFLEX FRZ pipe insulation is a professional-grade polyethylene foam sleeve engineered to provide superior thermal protection for heating and plumbing systems. With an inner diameter of 18mm and a wall thickness of 13mm, this insulation is specifically designed to minimize heat loss in hot water pipes and prevent condensation on cold water lines, thereby protecting the integrity of your piping infrastructure.
Advantages
This insulation material offers exceptional thermal efficiency due to its low thermal conductivity coefficient of 0.035 W/(m·K). The closed-cell structure of the polyethylene foam ensures long-term durability and resistance to moisture absorption, which is critical for maintaining consistent performance over time. Its lightweight and flexible nature allows for quick and easy installation even in confined spaces, while the robust material density of 40 kg/m³ provides reliable protection against mechanical wear and environmental factors.
Suitable for
Residential heating and plumbing pipe systems
Commercial water distribution networks
Preventing condensation on cold water pipes
Reducing energy loss in hot water supply lines
When it may not be suitable
This product is not designed for outdoor use where it would be directly exposed to prolonged UV radiation, as the material may degrade over time without additional protective covering. It is also not suitable for high-temperature steam pipes that exceed the maximum operating temperature limit of 95°C.
Key specifications
Material: Polyethylene foam
Inner diameter: 18 mm
Wall thickness: 13 mm
Length: 2 m
Operating temperature range: -80°C to +95°C
Thermal conductivity: 0.035 W/(m·K)
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 sleeve to the required size using a sharp knife. If the pipe is already installed, the sleeve can be slit longitudinally, placed around the pipe, and secured using appropriate adhesive or tape to ensure a tight seal. Ensure that all joints are tightly butted together to prevent thermal bridging.
What to consider before purchase
Verify the outer diameter of your pipes matches the 18mm 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 sleeve is 2 meters long.
Usage recommendations
For optimal thermal performance, ensure that all seams and joints are fully sealed with compatible insulation tape to prevent air gaps and moisture ingress.
