I had to pick between a standard ceramic fiber blanket and a higher density one for the new insulation layer. Went with the high density stuff, cost about $150 more for the roll. It's holding temp way better now, my color work is way more consistent. Anyone else in a cold climate notice a big difference with different furnace linings?
Yeah, the "no real issues" part is key. That standard blanket works fine until you get a weird-shaped part or a deep draw. It's one of those things you don't miss until you need it.
