5 layers, 1 pipe – the aluminium multi-layer composite pipe
The Variotherm aluminium multi-layer composite pipes use the advantages of both aluminium and plastic. That makes them flexible, yet with a stable form. The innermost layer of the VarioProFile pipe and the Variomodular pipe consists of polyethylene, and is extremely temperature resistant. The laser-welded aluminium pipe is 100% oxygen diffusion-tight.
