Windows & Door fitting

Industry standards for uPVC windows and doors

I have had a uPVC window & door fitted. They are joined by a metal girder-like section, presumably for strength. The 'girder' was pre-attached to the window (I think), seemed to be screwed to one edge. It runs the full height of the window and almost the thickness of the door frame. On either side the fitter glued thin plastic strips to cover the approx 5-10mm gap between door frame & window frame. To me, the metal will conduct heat from inside out. Relying on two lots of thin air gap plus silicon plus 1-2mm of uPVC seems inefficient. Is this industry standard? They are 'A' rated windows but what's the point if the heat leaks away around the edges? I guess the answer is test it on a cold day. If the seam is warm on the outside or cold on the inside then I guess I was right. However the company will have my money and I will have egg on my face.
