Found an old thread with a dead link to a write up on hearth extensions… any help finding it? 
Local shop wants $300-400 I think for a 18x48 extensions. Seems like it’s just a powder coated piece of sheet metal. Can’t bring myself to pay that. I’ve got an elevated hearth so I don’t t think I need anything special. Just ember protection. UL1618 type 1. We used a wool hearth rug before but we’re told that’s not adequate. Makes sense to me that we’d want better than that.
