## Long description

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 42 mm and a robust wall thickness of 20 mm, this insulation effectively minimizes heat loss in hot water pipes and prevents condensation buildup on cold water lines. Its closed-cell structure ensures long-lasting performance and energy efficiency in both residential and commercial applications.
Advantages
The primary benefit of this insulation is its high thermal efficiency, characterized by a low thermal conductivity coefficient of 0.035 W/(m·K), which significantly reduces energy consumption. The material is highly durable with a density of 40 kg/m³, offering excellent resistance to mechanical stress and moisture. Its flexible nature allows for quick and easy installation on various pipe configurations, ensuring a snug fit that maintains its integrity over time across a wide operating temperature range.
Suitable for
Heating system piping
Domestic hot and cold water supply lines
Plumbing installations in residential buildings
Commercial pipework requiring condensation control
When it may not be suitable
This product is not designed for outdoor use where it would be directly exposed to intense UV radiation, as the material may degrade over time without additional protective cladding. It is also not suitable for high-temperature industrial steam pipes that exceed the maximum operating temperature of +95°C.
Key specifications
Material: Polyethylene foam
Inner diameter: 42 mm
Wall thickness: 20 mm
Length: 2 m
Operating temperature range: -80°C to +95°C
Thermal conductivity: 0.035 W/(m·K)
Density: 40 kg/m³
How to use
To install the insulation, measure the length of the pipe section and cut the foam sleeve to the required size using a sharp knife. If the pipe is already installed, use a longitudinal cut to open the sleeve, wrap it around the pipe, and secure the seam with appropriate adhesive or insulation tape. Ensure all joints are tightly sealed to prevent air gaps, which could lead to condensation or heat loss.
What to consider before purchase
Verify the outer diameter of your pipes matches the 42 mm 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 for your project, keeping in mind each sleeve is 2 meters long.
Usage recommendations
For optimal results, ensure the pipe surface is clean and dry before applying the insulation. When insulating elbows or T-junctions, miter-cut the foam at 45-degree angles to ensure a continuous thermal barrier.
