Why Choose MLCP Pipes?

MLCP (multilayer composite pipe) offers the best of both worlds, combining an aluminium core with inner and outer layers of durable polyethylene. This construction provides strength, flexibility and oxygen diffusion protection in a single solution.

Here are some of the key benefits of using MLCP pipes:

• Excellent shape retention thanks to the aluminium core
• Reduced thermal expansion compared to standard plastic pipe
• Built-in oxygen barrier to protect heating systems
• Suitable for high-pressure and high-temperature applications
• Flexible yet strong, making installation quicker and easier
• Compatible with press fittings and compression systems
• Ideal for both heating and potable water plumbing

Whether you're installing underfloor heating pipework or upgrading a central heating system, multilayer composite pipe offers long-term reliability.

MLCP Pipe for Underfloor Heating & Plumbing Systems

MLCP pipe is widely used in wet underfloor heating systems due to its durability and resistance to oxygen ingress. The aluminium layer prevents oxygen from entering the system, helping to protect pumps, manifolds and valves from corrosion.

For plumbing applications, multilayer pipe provides consistent internal bore sizing and smooth flow characteristics, supporting efficient water distribution throughout the property.

Available in common sizes such as 16mm, 20mm and 25mm, MLCP pipes are suitable for both standard and low-profile underfloor heating systems.

MLCP Pipes vs PEX or PERT Pipe

When choosing between MLCP pipes and standard PEX or PERT pipe, the main difference lies in construction and performance.

MLCP pipe features an aluminium core, which minimises pipe expansion and contraction. This also helps the pipe hold its shape once bent, and provides an overall increase in structural strength.

PEX and PERT pipes, on the other hand, boast both greater flexibility and are more cost-effective than MLCP Pipes. MLCP piping is often preferred where stability, durability and long pipe runs are required.
