| When lookin thru the certified products directory, I notice that there are several plastic dome skylights using thermalized aluminum frames that have very different u-factors. When I look at the details of these different units they do not appear to be very dissimilar yet the u-factors are extremely different. Can anyone give an explanation of this? |
