## Long description

The ISOVER Mineral Wool Pipe Insulation Shell 42/20 is a high-performance insulation solution engineered for the thermal and acoustic protection of pipelines. Measuring 1.2 meters in length with an inner diameter of 42 mm and a wall thickness of 20 mm, this rigid mineral wool segment is designed to minimize heat loss in heating and plumbing systems. Its robust construction provides reliable fire resistance and long-term structural integrity, making it a dependable choice for both residential and industrial applications.
Advantages
This insulation shell offers exceptional thermal efficiency, significantly reducing energy consumption by preventing heat transfer from the pipe surface. The mineral wool material is inherently non-combustible, providing an added layer of fire safety to the installation. Its precise dimensions ensure a snug fit around standard pipes, which simplifies the assembly process and minimizes thermal bridging. Furthermore, the material is resistant to aging and maintains its insulating properties over a long service life, even under varying temperature conditions.
Suitable for
Residential heating and hot water supply pipelines
Industrial process piping systems
Acoustic insulation for metal pipe networks
Protection of pipes in technical rooms and basements
When it may not be suitable
This product is not intended for use in environments with constant direct exposure to liquid water or high humidity, as mineral wool can absorb moisture if not properly protected by an external vapor barrier or cladding. It is also not suitable for pipes with external diameters significantly different from the 42 mm specification, as an improper fit will compromise thermal efficiency.
Key specifications
Inner diameter: 42 mm
Wall thickness: 20 mm
Length: 1.2 meters
Material: Mineral wool
Fire resistance: Non-combustible
How to use
To install, open the longitudinal slit of the insulation shell and wrap it securely around the pipe. Ensure that the seam is tightly closed and aligned along the length of the pipe. For optimal performance, secure the shell in place using appropriate adhesive tape or metal bands at regular intervals. If multiple segments are used, ensure that the butt joints are tightly pressed together to prevent thermal leakage at the connection points.
What to consider before purchase
Verify the exact outer diameter of your pipe to ensure compatibility with the 42 mm inner diameter.
Assess whether additional protective cladding is required for outdoor or high-moisture environments.
Calculate the total length of the pipeline to determine the number of 1.2-meter segments needed.
Usage recommendations
For maximum efficiency, ensure that all joints are sealed with professional-grade aluminum foil tape to maintain a continuous thermal barrier and prevent air infiltration.
