I would like to build a fieldstone fireplace and put in a direct vent propane fireplace insert. I would be splitting the stone to 3 inches thick and putting them onto a plywood frame covered by felt paper,wire mesh and a scratch coat. My plan is to go to the ceiling 9ft with a chimney for looks. The unit will built on a 6 inch thick cement floor.
Could there be a problem with the weight of the stone either sticking to the scratch coat or with the plywood structure overall? THANKS
When you say "fieldstone", I think of granite. If that's the case, I think you may have a struggle trying to get 3" thick granite to stick, partially due to the weight & partially due to the density (they don't "grab" well.)
How do you plan on splitting them, and are you sure the floor is 6" thick?
Thanks for the reply! I'm from Iowa the field stone here are not granite. They are just stones of various shapes, sizes and textures laying on top of the ground in our corn fields, I am splitting them with hammer and chisel it take time but it can be done if you really study the grain of the rock, Although there are many 4 5 and 6 inch rock across the face that are flat on one side that will work for me the biggest one weighing 6 lbs. 2 and a half inches thick seems to be the norm. I am building this in my garage that I built recently so I'm sure the floor is 6 inches thick and thicker on the edges for the footings.
