Product Overview

The Profitherm AL multilayer pipe is a high-performance composite pipe designed for underfloor heating (UFH) and low-temperature heating applications. It features a five-layer construction combining the flexibility of polyethylene with the strength and stability of an aluminium core.

Manufactured in accordance with EN ISO 22391, both the inner and outer layers are produced from raised temperature resistant polyethylene (PE-RT), ensuring excellent thermal stability and long-term durability. The aluminium layer is butt-welded and fully encapsulated between adhesive layers, providing complete 100% oxygen impermeability and protecting heating system components from corrosion.

The aluminium core significantly reduces thermal expansion, allowing the pipe to retain its shape during installation and operation, while still remaining flexible enough for easy laying in UFH systems.

Key Features & Benefits

  • Multilayer Construction: PE-RT / adhesive / aluminium / adhesive / PE-RT
  • 100% Oxygen Barrier: Aluminium core prevents oxygen diffusion, eliminating corrosion risk
  • Dimensional Stability: Aluminium layer reduces expansion and pipe memory
  • Flexible & Easy to Install: Maintains shape while allowing smooth bending
  • High Temperature Resistance: Suitable for underfloor heating and low-temperature heating systems
  • Standardised Dimensions: Compatible with standard UFH fittings and manifolds

Frequently Asked Questions

  • What’s the difference between multi-layer and PEX underfloor heating pipe?

    PEX pipe is flexible and widely used for underfloor heating, while multi-layer pipe incorporates additional layers that can improve shape retention and reduce thermal expansion. The correct option depends on the system design and compatible fittings.

  • How much underfloor heating pipe do I need for my floor area?

    Pipe quantity depends on the heated floor area, pipe spacing, number of loops and maximum suitable loop length. A designed UFH layout provides a more accurate quantity than calculating from floor area alone.

  • What underfloor heating pipe spacing should I use?

    Pipe spacing should be determined by the room’s heat loss and required heat output rather than room type alone. Areas with higher heating demand may require closer pipe spacing.
