I drop in 15° in your attic isn't going to help at all with the temp in your house. All smoke and mirrors. Insulation will help more. The heat from the attic doesn't hardly "leave" the attic and warm the ceilings. And if it did, the warm air would stay up near the ceilings. Waste of money. Smoke and mirrors with no supporting evidence. It will make the attic 10-15 degrees cooler if you are thinking about living in it
