And a very quick update - I took a tape measure to ours and the opening we have is certainly less than 7 foot - it's difficult to be precise, as there is render slightly overlapping the frame, but I got it to be about 80 inches. We didn't know that insulated was an option - and in fact, with a wooden back door to the same garage, it would have been pointless for us in any case - so I can't answer that for you.Aha, well York matches the style of what we've been looking at and I do like the sound of the 'continuous hinge' design. I'll have a mooch at their website, can't see if they offer insulated as an option.
