Standards

®
Vesbo ALPEX Multilayer Pipe combines the advantages of:

Metal Plastic

Low thermal expansion Resistant to corrosion and
incrustation
Impermeability to
diffusion Lightweight
 DIN 16892

Dimensional stability.
 DIN 16893

 Floor heating systems work with low parameters, which limits energy consumption.  ISO 10146

 It allows to decrease temperature by 1-2 ˚C, saving from 6 to 12% of energy.  DVGW W542

 ISO 21003-2
