The clickfix principle is a patented connecting system by VENTAFLEX^®.
It ensures inexpensive transport as well as especially easy installation.        
The pipes are produced in the form of half-shells, which enables the transport
of almost twice the amount of pipe and in this manner leads to
a considerable reduction of the transport costs. Moulded parts are delivered
pre-assembled as standard.

Additionally, the very easy and patented VENTAFLEX® clickfix connection together with the extremely light weight of the hard foam pipes enables comfortable handling on the building site.                                                             
With the VENTAFLEX^® clickfix system it is possible to realise insulation of
ventilation pipes afterwards.
