DOYMA CURAFLAM® SEGMENT SMPRO

From the jury's assessment

The “Curaflam® Segment SM pro” is the first system for all conventional flammable pipe systems (both drainage pipes and supply conduits) available on the market. Thanks to its modular construction, multiple SM pro segments can be linked together to cover all standard sizes. That means you always have the right length of sleeve available, regardless of the pipe system being used.
