Wow, what a nice spray pattern out of that Fusion Clear Shot gun! What a great application for foam! It looks like you have about 2 feet of space above the bottom of the colar tie part of the truss. There is no room to put loose fill or fiberglass in there and then put a gable vent to take out all of the moisture that passes through the loose fill or filterglass. The gable vent would have to be in the middle of the loosefill and allow tons of airflow through it reducing it's R-value to zip!

Wow that must be at least R-21, lol. Loosefill on your ceiling means no thermal bridging like you have which would lower your overall r-value to LOWER than R-20, good job ripping somebody off. Loosefills eliminate thermal bridging, can go to R-60, or 3 times what foam is usually installed at, is NOT made out of petroleum, allows harmful VOC and indoor humidity through it and out of the house, is made from recycled content and sand, and costs less......DUH.

Well HomeEnergyNow, you sound like a pissed off loosefill contractor that is losing work to higher quality foam insulation. If you knew your stuff, you would know 5" of foam is an R-35 and loosefill on your ceiling means, leakage around any recessed lights, piping penetrations and an average attic temp. of 140 degrees. That sure makes life easy for your AC unit, doesn't it? Oh, and you forgot to mention with loosefill you NEED an R-60 or more!
