Blanket: Batt and Roll Insulation Blanket insulation -- the most common and widely available type of insulation -- comes in the form of batts or rolls. It consists of flexible fibers, most commonly fiberglass.
1 In the United States, rapid-acting insulin, Lyspro (humalog) is mixed with NPH in a 50:50 (50% NPH and 50% insulin Lyspro) and 75:25 (75% NPH and 25% insulin Lyspro) ratio.  Insulin/Aspart (Novolog) combinations also are available as 70:30 mixtures (70% NPH, 30% insulin aspart).
Before the new insulin pens came out, there were four types of insulin: rapid-acting, short-acting, intermediate-acting, and long-acting. When it comes to the pre-mixed insulins, like Novolog 70/30, there are fewer differences between the brands (for example, Novolog versus Novolin).hen it comes to the pre-mixed insulins, like Novolog 70/30, there are fewer differences between the brands (for example, Novolog versus Novolin).
