  • Insulation Performance: Meets BS3924, BS3887 and IEC 60454 standards, offering flame retardant and water-resistant protection
  • Best for: Professional electricians and DIY enthusiasts needing reliable wire insulation and repairs
  • Not ideal for: Applications that require structural bonding or specialist high-temperature sealing solutions

Safety standard compliance and flame retardancy reduce fire risk while resisting moisture. Flexible PVC with a strong adhesive gives dependable coverage for routine wiring tasks.


Code-compliant protection – thanks to BS and IEC standard compliance

Compliance with BS3924, BS3887 and IEC 60454 indicates base material and adhesive meet recognised tests for flame retardancy and electrical insulation. Those tests assess behaviour under heat, flame and electrical stress.

Reduced safety risk for household and light commercial wiring, giving confidence when insulating joints and cable splices.

Weatherproof performance – with water-resistant PVC construction

Water-resistant PVC repels moisture and helps maintain dielectric integrity in damp conditions. The PVC backing also remains flexible rather than hardening when exposed to moisture.

Suitable for outdoor weatherproofing and damp locations where maintaining insulation is essential.

Fast, tidy repairs – with strong PVC adhesive and easy-tear material

Strong adhesive bonds to a variety of cable sheaths while flexible PVC conforms to irregular shapes; the tape tears easily for quick application without scissors.

Smooth wrapping and secure adhesion allow neat repairs and clear colour-coding across multiple jobs.
