## Long description

THERMAFLEX FRZ pipe insulation is a professional-grade thermal solution engineered for heating and plumbing systems. With an inner diameter of 35 mm and a wall thickness of 20 mm, this polyethylene foam insulation provides a robust barrier against heat loss and condensation. Its flexible structure ensures reliable performance in both residential and commercial piping networks, contributing significantly to overall energy efficiency.
Advantages
The primary benefit of this insulation is its high-performance polyethylene foam material, which offers excellent thermal resistance with a conductivity coefficient of 0.035 W/(m·K). The material is lightweight yet durable, featuring a density of 40 kg/m³. Its flexibility allows for quick and efficient installation around bends and fittings, ensuring a snug fit that maintains its integrity over time. By minimizing thermal bridging, it helps maintain consistent fluid temperatures and protects pipes from environmental fluctuations.
Suitable for
Heating system piping
Plumbing and water supply lines
Residential and commercial building infrastructure
Preventing condensation on cold water pipes
This product may not be suitable for outdoor applications exposed to direct, prolonged UV radiation without additional protective cladding. It is also not intended for use in high-temperature industrial steam lines that exceed the maximum operating temperature of +95°C.
Key specifications
Material: Polyethylene foam
Inner diameter: 35 mm
Wall thickness: 20 mm
Length: 2 m
Thermal conductivity: 0.035 W/(m·K)
Operating temperature range: -80°C to +95°C
Material density: 40 kg/m³
To install, measure the pipe length and cut the insulation to size using a sharp knife. Open the pre-slit foam tube, wrap it around the pipe, and secure the seams using appropriate adhesive or tape to ensure a continuous thermal seal. Ensure the pipe surface is clean and dry before application for the best adhesion results.
What to consider before purchase
Verify the outer diameter of your pipes matches the 35 mm inner diameter of the insulation.
Check if the 20 mm wall thickness meets the specific insulation requirements for your local energy regulations.
Ensure the operating temperature of your system stays within the -80°C to +95°C range.
For optimal energy efficiency, ensure all joints and seams are tightly sealed with compatible tape to prevent air gaps and moisture ingress.
