These are new to me but appear suitable with 4 hour fire rating.Look into the use of some AAC blocks ( Autoclave Aerated Concrete they are larger than bricks , light weight & can be cut with a hand saw to thickness. Also know as Hebel Blocks.
In your area with all the big construction you should be able to get a few.
I just finished building a composite deck. I don’t want to use the smoker on top of the deck for fear of “melting” or whatever would happen to composite decking. I have about 7’ under the deck which is open on 2 sides and a house on the other 2 sides. Has anyone smoked under a deck before? See any issues with it? I’d be using a Bradley Electric and a Masterbuilt dual-fuel smoker. Thanks.We use a cheapo electric smoker, the red steel pill shape type. Deck is the most convenient place to operate the smoker grill, and is composite material. I have been temporarily using the door off our spare range as a "fire block" so I don't melt the deck, but would like a more permanent solution. Was thinking about insulating fire bricks. Any better ideas?
