My new 44-year-old house has an oil-fired hot air heating system, and the ducting is non-insulated. I would like to wrap insulation on the outside of the ducting, in the crawlspace and other exposed areas, but they get pretty warm. What would be a good and safe insulation product?
Also, this particular home does not have any insulation in the walls (lucky me). I know some about blown-in insulation, but another unique feature of this home is that all the rooms have the heat registers at the base of exterior walls, not the floor. By base, I mean, like 6″-8″ off the floor. Will the heat from the ducts in the lower walls pose a problem when the blown-in insulation is added?
Thanks in advance – TomR

I also have a problem with my heating the second floor bedrooms. Lots of cold air in the winter months. Lots of heat in the summer months. How can I insulate my attic better to prevent heat loss in the winter and cooling in the summer?

First i’d like to thank you for taking the time to read this message, but my main reason for writing this was because i was i was trying to conduct an experiment on what would be the best insulator for a heating system. i was going to try an array of different metals/ceramics, then narrow down my list to the most commonly used substances.

I purchased a house with 1 vent in the middle of my house. It heats up the hall way then the heat seaps out to warm the house. I would like to add ducts to all my rooms and get rid of the big hole in my floor. I have 1 trunk that comes from my heater. I dont know how big the trunk should be and how to get the heat to other locations. I can acess my whole house from the basement.
