Yes, they were added to the cardboard ones that were already installed in the bays. Since I added several inches of cellulose, we needed to extend those up. I purchased a electric staple gun just to put them up. Glad I did because of the angle, and having to work over existing fiberglass insulation. There is a massive difference in the comfort in the house now. The $300 was totally worth the expense.
The next energy saving project is to seal above the door jams. It's amazing how much they leak at the top of the molding.
