This was the first time I've really looked around the attic. There's a big, fluffy pile of insulation through most of the attic, but a plywood walkway near the AC ducts. I think there's spray foam under the plywood. Would it be wise to cut some easily-removable sheets of insulation and lay them down on top of the plywood? It seems like a gaping thermal hole in comparison to the giant stack of blown-in insulation.
The Tesla solar installation is scheduled for October. I think my next project will be more shade trees in the back yard because the poor grass is scorched. We are considering the very tall, thin juniper.
