Armaflex Tape

Armaflex Tape

Armaflex self-adhesive tape is the professional solution for sealing joints, repairing damaged insulation and finishing exposed edges on Armaflex pipe and sheet insulation installations. Made from the same closed-cell elastomeric rubber as Armaflex insulation itself, it maintains the same thermal performance and vapour resistance across every joint — something generic insulation tapes cannot match.

Why Use Armaflex Tape?

  • Same material as Armaflex insulation — consistent thermal conductivity and vapour resistance at the joint
  • Self-adhesive backing — fast, clean application without mixing or waiting for adhesive to dry
  • Flexible and conformable — follows curves and irregular surfaces without lifting or cracking
  • Maintains the vapour barrier — prevents moisture bridging at joints and repairs
  • Suitable for all Armaflex grades — compatible with Class O, EVO, Ultima and sheet insulation

Frequently Asked Questions

Can I use Armaflex tape instead of adhesive?
For most butt joints and longitudinal seams, Armaflex 520 adhesive gives a stronger, more reliable bond. Armaflex tape is best used for repairs, finishing edges and sealing joints in locations where applying adhesive is impractical.

Is Armaflex tape waterproof?
Yes. Armaflex tape is made from closed-cell elastomeric rubber with a very low water vapour permeability, making it resistant to moisture and suitable for use on cold pipework where condensation control is required.

What width of Armaflex tape do I need?
Standard Armaflex tape is available in 50mm width, which is suitable for most pipe insulation joint sealing and repair applications. Wider tape may be used for sheet insulation edge finishing.

Can Armaflex tape be used outdoors?
Standard Armaflex tape is not UV-stable and should be protected from direct sunlight in outdoor installations. For exposed outdoor applications, use an appropriate UV-resistant jacketing or coating over the tape.
