Committed to the use of Polybutene-1

For Nueva Terrain, Polybutene-1 (Polybutylene) is the thermoplastic with optimal physical and mechanical characteristics for pressurised hot and cold water piping.

These characteristics, in conjunction with the variety and reliability of the jointing techniques available for the Nueva Terrain PB-1 piping system, make it an excellent choice for a broad variety of project installations. Nueva Terrain has additional information on its website in the form of Technical Product Sheets and Technical Notes that expand on various topics such as installation, legislation and instructions for assembly.

Nueva Terrain offers it's customers the following benefits:

PB-1 systems for the distribution of drinking water

The primary objective of Nueva Terrain for its Terrain SDP system is to satisfy the highest quality piping system requirements. As a result, through an especially rigorous selection process and criteria, PB-1 was the chosen material.

The decision was based on research and development, in-depth knowledge of plastics technology as well as supplementary options to allow the system to further evolve in line with future industry trends in installation and jointing.

As a consequence of in-depth studies and tests both in our own laboratories and from independent testing organisations, the conclusion was reached that the optimum raw material for the Terrain SDP system was PB-1, a partially crystalline polyolefin thermoplastic with high long-term performance and a high resistance to flow at high temperatures – properties that are essential for interior hot and cold water installations as well as for heating.

Polybutene-1 (also known as Polybutylene), the universal plastic material that allows joints by fusion welding and also by mechanical fittings, combines numerous key characteristics for piping systems including:


Due to its best-in-class resistance to high temperatures compared to other plastics, PB-1 permits lower wall thicknesses for identical usage profiles which, in turn provides larger internal transport diameters for the same external diameter, resulting in lower velocities for the same flow, lower head losses and a lower pipe weight per metre.

In addition, PB-1 has an excellent energy audit compared to other materials of the same application making it the product with the lowest environmental impact. As a polyolefin, PB-1 is of course completely recyclable.

The Nueva Terrain Polybutene-1 SDP piping system for drinking water and heating

The Terrain SDP system of pipes and fittings manufactured in PB-1 for the distribution of hot and cold water and heating offers the following advantages:

Nueva Terrain Polybutene-1 joint systems

Nueva Terrain offers four different joint systems depending on the requirements of the project installation and installer.

The advantages of PB-1 as a material for pressurised hot and cold water piping systems for drinking water and heating also include the many options available for joints which are quick to make, and when installed as prescribed, deliver long-life integrity under challenging environmental conditions. This is why Nueva Terrain requires their own pipes and fittings to be used in order to guarantee the installations.

Please note, combining components from different systems can cause or contribute to installation failure regardless of the individual quality of each component. PB-1 as a material has optimum characteristics for connection using the most versatile and varied systems: mechanical joints and fusion or thermal welding.

Nueva Terrain offers four different joint systems depending on installation and installer requirements:

These joint systems mentioned above, as well as the comprehensive range of diameters and variety of fittings, result in a complete product portfolio that provides solutions to the most varied of installations with the best materials and systems available.

List of applicable standards and legislation

Product Certification - AENOR product marking
The AENOR marking is a sign of conformity with the corresponding standard production. It certifies that the products that receive it have passed the assessments and controls that are established in the certification systems, thus guaranteeing the user a quality product. AENOR is a constituent member of the CEN (European Committee for Standardisation) that groups the national standardisation bodies of more than 30 European countries. It is therefore an internationally recognised and trusted marking due to its demands and presence in the market.

International standards listed in the previous section are not mandatory. In each country there is legislation that must be met before installing pipe and fittings for drinking water supply and heating. Usually international standards are more restrictive than national legislations which is why manufacturers are certified according to these standards and thus ensuring the conformity of the product.
