This is very interesting, we are just about to order a roof system and was going for this one (Terrano) in aluminium but maybe that will be even worse in the wind as its lighter. What is you roof buildup underneath the membrane?

Hi makingprogress, did you have any luck with getting a low U value door? I am looking for the same for an linked garage and I can only find a steel 1.3 W(m2)k so far
