Hi anyone, I have a multifuel stove installed. There is a 5 cm gap between the back and the wall behind. I'm wondering if there is some kind of really thin board I could stick to the wall behind to offer it some increased protection form the heat. Obviousy space is quite limited. I have loked around the web but am a bit confused by the options. Also, it would need to be paintable. Any pointers apprecaited, cheers, Rod
