The answer to the question of which attic insulation is best is, of course, entirely circumstantial. When the design of your attic allows, the best attic insulation is inexpensive, easy to install and will yield the performance you're looking for.
I'm a huge fan of Building Science teacher Joe Lstiburek and I'm finally building my first house with his "Perfect Wall" concept. Join me as I explain this theory for extreme durability and efficiency (and show off a house I'm building in Austin).

There are 4 things every house must control (in order of importance). 1. Water 2. Air 3. Vapor 4. Thermal Codes have only started to address air control and I think many builders in the US are behind in this area.

Planning a high-performance house in Massachusetts, Bill L asks the Green Building Advisor's Q&A Forum how to build in an air barrier that will stand the test of time. He's not sure that specialized construction tapes are the way to go.

Mark LaLiberte is an amazing building-science teacher. Read my blogging notes from his seminar titled "Building High-Performance Homes Dos & Don'ts," which I attended in Austin, Texas. Remember that this is focused on Texas construction, but there is plenty to learn here for anyone in the U.S.

Al Cobb's goal is simple: Build better houses and help consumers make better choices. To do that more effectively, he wants to understand the root causes of heat loss a little better. Are air leaks or low insulation levels the real culprit?
