This is a quick summary table of all the common types of thermal house insulation. You can find details on each material by looking up "insulation" then "types".

We can't stop heat from escaping from the house by conduction, but we can effectively slow it down with thermal insulation. In practical terms, just about the only insulating material we work with is dead air. All the fibers, foams, beads, and batts are just different ways to package dead a...
Yes. R values simply add together to give a total R for the wall or ceiling. Generally speaking, a denser insulation should not be put on the cold side of a less denser one; it's a question of letting the moisture escape as easily as possible and not creating double vapour barriers. Hence, loo...
There are so many different insulating materials that it is quite confusing. I have tried to pull together information on the most common types from the manufacturers, the critics, the contractors and the researchers. Usually this information seemed to me to be either too simplified or too ...
