Please see the attached images. What is the proper name for the little wedges about half-way up on the hinge side of a UPVC window? I assume they are there to improve the seal of the sash when closed.
In my case they don't seem to be doing their job as there is a small gap in the seal. Looking closely at the wedges when closing the window, they don't seem to be touching each other at all so don't seem to be doing the job I assume they are there for - there is a several millimetre gap between the wedges when closed. I would like to buy bigger wedges, but it's hard when I don't know the proper name for them!
