Is It Time to Give Copper the Elbow?
Exploring the benefits of multi-layer piping over copper and other materials
As global copper prices continue to climb, installers across the industry are feeling the pressure. What once felt like a reliable, go-to material is becoming increasingly costly — prompting many to reconsider whether copper is still the best choice for modern projects.
At Geberit, we believe this moment presents an opportunity to look forward. With proven alternatives now offering compelling advantages, it may indeed be time to “give copper the elbow.”
Global demand for copper is currently outstripping supply, driven by factors such as electrification, renewable energy expansion, AI data centres and ongoing supply disruptions. As a result, prices reached an all-time high of USD 13,842.50 per tonne in early 2026.
While these global figures may seem distant, their impact is felt daily on-site. Installers are experiencing:
• Increased material costs
• Reduced margins
• The need to frequently reprice jobs
Since 2023, the price of copper pipe has already risen by around 25%, and projections suggest it could more than double by 2028/29.
Faced with this uncertainty, many installers are now exploring alternative pipework materials that offer greater cost stability.
Multi-layer piping is not a new technology. In fact, it has been used in the UK for more than 40 years. However, rising copper costs and advances in system design are now driving renewed interest.
Systems such as Geberit FlowFit combine the best of both worlds — delivering the stability of metal with the flexibility of plastic.
Geberit FlowFit multi-layer pipes consist of three layers:
• Outer layer (PE-RT): Protects against corrosion and mechanical damage
• Aluminium core: Provides strength, stability and flexibility
• Inner layer (PE-RT): Ensures corrosion resistance within the pipe
This construction allows the pipe to retain its shape while remaining easy to bend — offering both durability and adaptability.Additional advantages include:
• Built-in oxygen barrier, making it suitable for heating systems
• Compatibility with electronic detection after installation
• Low scrap value, reducing risk of theft on-site
Where multi-layer systems truly stand out is during installation.As copper prices rise, installers are increasingly recognising the value of systems that not only reduce material costs but also save time and labour.Key Installation Benefits
• Simplified tooling: Only two pressing jaws required for the full Geberit FlowFit range (d16–d75)
• Manual bending: Smaller pipes (d16 and d20) can be bent by hand, reducing the need for elbows and fittings
• Fewer pipe supports required:
o d20 copper: 1.2m spacing vs. 1.5m with Geberit FlowFit
o d54 copper: 1.8m spacing vs. 2.5m with Geberit FlowFit
• Lateral pressing technology: Press fittings from one side for easier access
• Visual installation checks: Inspection windows and colour indicators ensure correct assembly
Collectively, these features significantly streamline installation. In fact, Geberit FlowFit has been shown to be up to 274% faster than traditional press-fit copper systems.
Efficiency gains don’t stop at installation. Flow-optimised design reduces pressure losses, allowing for smaller pipe diameters and lower material usage — further driving cost savings.
Real-World Example*
On a care home installation project:
- Multi-layer press-fit systems delivered a 19.3% saving (materials + installation) compared with copper in February 2025
- With copper price increases:
- 23.2% cheaper by March 2026
- 24.55% cheaper projected by December 2026
These are substantial savings that can have a major impact on project viability and profitability.
We understand that changing established practices in construction is not always easy. Copper has long been trusted — and for good reason.
However, with mounting cost pressures and the increasing demand for efficiency, many installers are now embracing multi-layer systems as a smarter alternative.
At Geberit, we are committed to supporting this transition with innovative solutions like Geberit FlowFit — designed to deliver:
- Reliable performance
- Faster installation
- Greater cost control
As the industry evolves, so too must the materials we rely on.
With proven performance, installation advantages and measurable cost savings, multi-layer piping offers a compelling case for change.
Perhaps it really is time to give copper the elbow.
