[QUOTE="doctorjj, post: 3251342, member: 7292"] Blown in fiberglass is the most common. Oak Ridge Labs did some studies on it though and during reallly cold temperatures, the fiberglass has micro convection currents that decreased its effectiveness. So when you need it the most, it works the worst. You can cap it with just a couple inches of blown in cellulose and gain, not only the added depth of the cellulose, but the full R value of what the fiberglass should be. [/QUOTE]
