Product Information

Full details

AF/Armaflex Evo is designed for professionals and DIY enthusiasts who need reliable thermal efficiency and condensation control for hot and cold water services, chilled water lines, and refrigeration systems. It offers excellent thermal performance and integrated antimicrobial protection, though users should ensure they correctly measure pipe diameters before purchase to guarantee a proper fit, as the slit design requires a secure seal to maintain its integrity.

FAQs

Can I use this for outdoor pipework?

Armaflex Evo is designed primarily for internal use; for external applications, additional UV-resistant cladding is recommended.

Is the material safe to touch?

Yes, it is dust and fibre-free, making it safe to handle without specialized protective gear, though gloves are recommended for professional practice.

What is the wall thickness?

This specific variant has a wall thickness of 19mm.

Does it contain harmful chemicals?

The material is professional-grade and designed to be safe, featuring Microban technology to prevent microbial growth.

Can I paint over the insulation?

Yes, you can use specialized water-based paints, but check manufacturer guidelines to ensure the coating does not affect the insulation's flexibility.

What is the length of each piece?

Each individual length is 2 meters long.

Troubleshooting

Condensation forming on the outside of the insulation

Check that the slit has been properly sealed with adhesive and that there are no gaps at the pipe junctions.

Insulation feels loose on the pipe

Verify the pipe diameter is exactly 15mm; if the pipe is smaller, the insulation may not provide the necessary thermal seal.

Adhesive not sticking to the slit edges

Ensure the surfaces are clean, dry, and free of dust or oils before applying the bonding agent.

Pros and Cons

Pros

  • Superior thermal efficiency reduces energy waste
  • Pre-slit design makes retrofitting onto existing pipes simple
  • Built-in antimicrobial properties ensure long-term hygiene
  • Effective condensation control prevents pipe corrosion
  • Dust and fibre-free construction is clean and safe to handle

Cons

  • Specific 15mm inner diameter is not adjustable for larger pipes
  • Requires proper sealing agents to maintain vapor barrier integrity
  • May require extra care during corner installation to avoid gaps

Setup, Compatibility & Care

To install, measure your pipe to ensure the 15mm inner diameter provides a snug fit. Once the insulation is wrapped around the pipe, the slit edges should be joined using an appropriate Armaflex adhesive or compatible tape to ensure a continuous vapor barrier. The material is designed for use on hot and cold water services as well as chilled lines. For care, keep the surface clean and inspect joints periodically to ensure no moisture is bypassing the insulation. Store lengths in a dry, cool area away from direct sunlight to preserve the material integrity before installation.
