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).
Insulin aspart suspension must be rolled gently between your hands to mix before use. Do not shake insulin aspart suspension. Ask your doctor or pharmacist if the type of insulin you are using should be mixed and how you should mix it if necessary. Insulin aspart solution also can be used with an external insulin pump.
