I just finished remodeling my kitchen. Partly myself, partly done by contractors.

When the cabinets were put in, they made it so that the opening for the oven was very tight. The oven now sits less than 1/2" to an adjacent wall. I'm worried about a fire hazard now.

I thought about lining the wall with ceramic tile, but honestly I don't think the oven would squeeze in after that. I also thought about a metal flashing on the wall, but then thought metal conducts heat.

My last idea is to cut into the wall and make a "buildt in" wall cavity, so I can add tile.

What else could I do short of tearing out the cabinets and newly installed granite counters?

Any Ideas?
