Any thoughts on how to hold insulation on the outside of an Adobe to get the temp down. I have some of that compact fiberglass sheets but they are the unfaced kind. Do anyone know of a tape that might stick to that and be heat resistant. I have to do something to try and retain heat, I don't need a 140* boiler room, although it is nice to get warmed up in. The front and door will be the most difficult as they room up to 500*. Not a good situation. I didn't really want to have to build a whole new secondary jacket to hold the insulation. Thanks.
