The ProWarm™ Pex-Al-Pex 12mm Barrier Pipe is the ultimate choice for a wide range of demanding applications. Designed with innovation and versatility in mind, this European standard pipe sets the benchmark for performance and reliability in the international market.

When it comes to quality, we spare no expense. Our ProWarm™ Pex-Al-Pex pipe is meticulously crafted using only the highest quality materials. The 12mm (outside) diameter ensures optimal performance, while adhering to European standards, guaranteeing superior quality and durability.

Featuring a triple-layered construction, this pipe incorporates an oxygen barrier that is 100% tight. This ensures the integrity of the system and prevents the ingress of oxygen, safeguarding against corrosion and extending the lifespan of the pipe. The carefully calculated diameter of the pipe enables maximum performance and flexibility, making it suitable for a variety of applications.

The middle aluminium layer of the ProWarm™ Pex-Al-Pex pipe plays a crucial role in heat diffusion, enhancing overall efficiency. This layer allows for excellent conductivity, making it ideal for low-temperature systems. With its superior heat distribution capabilities, this pipe minimizes the need for additional pipework, reducing installation complexity and costs.

At ProWarm™, we offer a comprehensive range of high-quality products, led by our ProWarm™ range. We understand that the installation of a durable and long-lasting pipe system is paramount in underfloor heating applications. Replacing a pipe system can be expensive and unnecessary. That's why we prioritize quality and durability in all our products.

For your peace of mind, all our ProWarm™ Pex-Al-Pex pipes are backed by a remarkable 50-year guarantee, surpassing any other manufacturer on the market. This guarantee reflects our commitment to providing you with a reliable and long-lasting solution for your underfloor heating system.

Choose ProWarm™ Pex-Al-Pex 12mm Barrier Pipe and experience the innovation, quality, and longevity that sets us apart from the rest.
