Any views on this mechanism of insulating conservatory roof? Have been looking at replacement roof but perhaps this may be more economical? What are the disadvantages?

The hinges on my doors include this which seems (at least to me) to serve little purpose - Thought it might allow hinge adjustment but can't see how it works. Not needed for any adjustment at present just asking for future reference.
