My stove is just beside my refrigerator. Temperature in the fridge will start lowering during cooking and I can see the freezer compartment starts to "melt" after long hour of cooking. There is no way for me to shift them away from one another. Hence, I thought of placing a heat repellent / resistant board (preferably with magnet to stick) on the side wall of my fridge to deflect the heat from cooking. Is there any place in Singapore I can get such material? Thanks in advance.
