Wunda’s high quality, premium multi-layered 16mm Pert-Al-Pert floor heating pipe with full approvals.

Ideal for use in both OVERFLOOR and UNDERFLOOR systems.

Product Information

Wunda's thermally dynamic 16mm Pert-Al-Pert pipe has an aluminium core that produces a higher heat output than ordinary Pex and Polybutylene pipe and is easy to use. It is easy to shape by hand and stays where it's put with no spring back. Our pipe is 100% oxygen tight and leak proof.
    • Ideal for Wunda's 20mm EPS Overfloor System
  • Ideal for all floor heating systems not exceeding 65C
  • National Institute of Hygiene Certificate
  • National Declaration of Conformity
  • PN-EN ISO 21003-2
  • Aluminium core
  • Higher output than plastic pipe
  • Leak proof pipe
  • Flexible aluminium and polyethylene
  • 50 Year Guarantee
  • Very low expansion and contraction, just 5cm in 100 linear metres which is similar to copper (Ordinary plastic pipe has an expansion/contraction rate of approximately 50cm in 100 linear metres)
  • 100% oxygen tight (oxygen ingress can rot boilers) - ordinary pipe is normally only 80%
  • Easy to shape by hand- easy to fit, stays where it's put with no spring back
  • Detectable under the floor
