Armaflex Pipe Insulation is a flexible, closed-cell, elastomeric black foam tubing ideal to insulate pipes in HVAC and plumbing applications. It can be used to insulate all types of pipework across all projects. Thanks to its low thermal conductivity, it effectively minimizes heat loss, thereby keeping hot water hot. This thermal pipe insulation is widely recognized for its performance.
Nitrile rubber pipe insulation sections also provide better freeze protection and are therefore used to insulate cold or chilled applications. Armaflex Pipe Insulation is Class O insulation and complies with building regulations, making it a top choice for pipe lagging across various sectors.
Made with superior quality nitrile rubber, this black pipe insulation has an in-built vapor barrier. This vapor barrier protects your pipes from corrosion, thereby minimizing damages to pipes. It helps improve the overall performance of the pipework and also increases the longevity of the pipes.
Not only that, Armaflex Pipe Insulation also has in-built microbe protection that does not allow bacteria of any kind to grow or flourish in the application. This feature helps restrict the growth of Legionnaires' bacterium, in particular, thereby reducing the risk of infection.
These unspilt nitrile pipe insulation sections are quite easy to install as well. They are cut to size using a sharp utility knife and easily installed around pipes using Armaflex adhesives like Armaflex 520. For outdoor pipe insulation, you will need to use appropriate cladding insulation like PIB or stucco aluminum cladding. For smaller applications, 2M pipe insulation coil is also available for convenience.
Key Features:
- Armaflex Pipe Insulation is a black rubber foam pipe lagging, ideal for insulating both heating and cooling pipe applications.
- Made with top-quality nitrile rubber for improved energy savings, it is perfect as rubber pipe insulation or foam pipe insulation.
- Built-in vapor barrier in Armaflex Pipe Insulation reduces the risk of condensation, adding extra durability.
- Nitrile rubber pipe lagging minimizes the risk of costly affairs like pipe freeze and pipe bursts.
- Class O pipe insulation complies with building regulations and ensures superior rubber foam pipe insulation performance.
- Restricts bacterial growth in pipework with built-in microbe protection.
Applications
Armaflex Pipe Insulation is a flexible elastomeric nitrile rubber foam is:
- Armaflex Pipe Insulation is a flexible foam pipe lagging made from elastomeric nitrile rubber foam, ideal for insulating heating and hot water pipes (service temperature up to +110°C).
- Perfect for insulating air conditioning, chilled, or cold water pipes with temperatures as low as -50°C, such as 2M pipe lagging rubber foam or 6mm thick pipe lagging and 10mm thick pipe lagging.
- For domestic pipe insulation, commercial and industrial pipe lagging. Whether it's 2M pipe wrap or larger coils like armaflex pipe insulation for comprehensive coil insulation, it covers all your pipe insulation needs.
