Default Re: hearth insulation question

well, it's in....we poured the insulating hearth and are moving on. Next question is about some free firebrick we have. I've read that rule of thumb is that we want to stay away from 2lb firebrick and use 8lb firebrick. Well, we have about 150 white firebrick that weighs 5 lbs. They are 8" long, 2 1/4" thick and 3 3/4" wide. We need advice....we're afraid to use them if it's not worth the chance! Help!

They sound ok to me.
Try putting one in your BBQ and heating it up for an hour or so.
See if it gets nice and toasty.

Then turn the bbq off and see how long it stays hot.

It doesn't sound like they are insulating bricks to me. Those would be the 2 lb bricks you referred to.

Nice work so far!

Dave

turns out what we have is not firebrick....it's basically white sand brick. Glad we checked it out. We just came back from the brickyard with a truck load of firebrick and here we go!!! We are moving right along
