Innovations that simplify and highlight
The ease of installation and maintenance of Polytherm products makes them an ideal choice for both builders and homeowners.
The PRESS FITTING system, which is unique on the market, makes it possible to unify three types of pipes: MULTILAYER, PEX and FUSIOPER. This means that different materials can be pressed using a single fitting and tool, which significantly simplifies the installation process.
The FUSIOPER pipe, manufactured in POLYETHYLENE (PERT II), stands out for its capacity to withstand working temperatures ranging from -20º to 90º. This pipe can be pressed, thermo-welded and electro-welded, which gives it great versatility and installation options adapted to different requirements.
