I live in Alaska, Juneau specifically. I just had an energy audit and the was told that I needed to have my crawl space insulated. I have a crawl space with a vapor barrier on the dirt floor, and closeable vents for air circulation. I installed solid foam insulation on the interior walls and solid foam insulation on the rim joist.
The fellow that completed my inspection told me he could install the recommended insulation of the floor joists. The work has been completed, but I am wondering if it was completed correctly.
Fiberglass batting without a vapor retardant was placed between the floor joists. Nothing is holding it in place except the resistance of the fiberglass to the wooden joists.
I have read that the proper method of insulation of the floor joist is to use fiberglass with a vaper retardant layer that is installed against the flooring. The insulation is held in place with netting, something called lighting rods, or clear plastic polyethylene sheeting - 6 mil.
I have not yet paid the fellow that completed the installation. He is also the state certified energy inspector. I really need some guidance.
Thanks so much for any assistance you might provide. This just does not seem to me to be a correct installation.
