I am not interested in endorsing any specific product I just want people to know what some of the options. However, I do think that you should get/install the best insulation you can possibly afford.
Here’s what I think you need to know:
Insulation is rated based on it’s resistance to heat flow, the R-Value. The greater the R the less amount of air and moisture penetration is possible. You’ll see it listed as R-3. We live in Minnesota, land of extreme temperature change. Getting the highest R-value is important to keep the cold air out in the winter and the hot air out in the summer. According to Energy Star our climate should have R-38 to R-49, here’s their chart.
There is more to come, as time allows.
