Hi
I've just had an aluminium bifold door install and on removing the window packers all 4 panes of glass move and you can feel air coming through. There are 4 metal bars holding each window in place. should there be a gasket between the windows and the metal frames holding them in place or do the panes get siliconed in?
Also, each double glazed unit has a small plastic hole. On the bifolds this hole is at the top of the pane whereas on other windows I've had installed they are at the bottom. Does it matter if the hole is at the top or the bottom of the pane?
Thanks for any help
