PE Pipes.
PE pipes are a good alternative to copper pipes and PVC drainage pipes. Lower CO₂ footprint than both and no chlorine compounds in production.

What is pe pipes?
PE pipes (polyethylene) are used for water supply, hot water distribution, and geothermal systems. They are flexible, frost-resistant, and easier to install than copper pipes. PE is easier to recycle than PVC and contains no chlorine compounds. It dominates the water supply pipe market in Denmark.
Carbon Footprint Compared
Negative carbon footprint (green) indicates carbon storage. Data based on EPD averages from ECO Platform and estimates per EN 15804.
Typical Applications
- check_circle Water supply pipes (drinking water)
- check_circle Heating supply and district heating
- check_circle Geothermal systems (ground loops)
- check_circle Drainage installations (HD-PE)
In Renovation
PE pipes are the preferred alternative for replacing old copper pipes and galvanised steel pipes. Flexibility makes it easier to pull through existing walls and floors than rigid copper pipes.
Questions about pe pipes
What is the difference between PE and PEX pipes?
PE is linear polyethylene — standard for water supply. PEX is cross-linked PE and is more heat and pressure resistant, used for underfloor heating and hot water distribution. PEX cannot be reshaped by heat and is harder to recycle.
Are PE pipes safe for drinking water?
Yes — PE pipes approved for drinking water (PE100, PE100-RC) are tested and approved for human use. They release no substances exceeding drinking water standards when correctly installed.
Can PE pipes freeze?
PE pipes are more frost-resistant than copper — they can expand slightly and can withstand brief freezing. However, water pipes should always be protected from frost by burying below the frost depth.
Is PE better than copper for climate?
Yes — PE pipes have approximately half the CO₂ footprint of copper pipes. For new water installations, PE and PEX are clearly preferable climatically.
