The flames of our gas hob scorches the wall behind it and the chipboard panel next to it. Is there any material I can affix to those sides to stop this potential fire hazard from happening?
Some sort of tile would do the job. If ceramic is too thick, or hard to install, adhesive stainless steel squares should be nicely heat conductive, thin, and easy to put up.
The range in our kitchen is pushed up against a wall (the chimney is behind it) so the back burner is in a corner. When I installed a ceramic tile backsplash I wrapped it around to completely cover this corner since I was noticing some discoloration of the paint from the gas burner. So far this seems to be working fine.
