Inspecting a high end home today that was built in 2008. When I was inspecting the attic, here's what I found. Foam insulation in the roof truss area, not the ceiling joist in the attic. Is this practice acceptable and how???? It seems to me that you would be heating the whole attic area with no insulation in the ceiling.. I need your feedback Please....

That's where you want the insulation. It's fine.

With HVAC ducts in the attic, I prefer it be conditioned.

If Done properly can work very well, any leaks in the roof wont show and will rot things fast. Check the fine home building website for more info. They can be problem"attic".

I inspected an attic like that one summer day on the Chesapeake. It was the most comfortable attic I've ever been in. No need to worry about sealing the hatch or nothing.

It sure can look odd but it does the trick. The trick is to insulate the entire building envelope. This way there is no air and moisture migration between enclosed insulated and un-insulated areas.
