I need something right now and fast. I was going to do this in the video and add a SOL Emergency Blanket on the inside to insulate the heat but I need to know what your thoughts are. I need something that will work in this winter weather and I can make cheaply. What I'm looking to do is have it as warm as possible inside of that space during the night even though it's winter. Please tell me your suggestions and if your going to tell me about a new product or something, can you link the information or place to purchase it?
