Galvanised ALFLEX
Galvanised ALFLEX
Galvanised ALFLEX
Galvanised ALFLEX is ideal for horizontal side flues or connecting distant terminals. Due to its rigidity, it delivers good mechanical strength between the rigid ducting and terminal in case of long lengths. It is designed for non-residential buildings and multi-occupancy housing.
The + products
