美国采购需求：保温耐火砖,jm系列保温砖

I have a room at home that often feels quite cold, and I'm looking for solutions to improve its insulation. I'm particularly interested in products that can effectively help with the walls to retain heat and create a more comfortable environment. Could you provide information on options you have available for wall insulation? I'm curious about the materials, installation process, and whether these products can significantly reduce the chill in the room. Also, any recommendations based on energy efficiency would be a plus!
