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).
Usually, one of the insulins will be cloudy and the other clear. Some insulins cannot be mixed in the same syringe. For instance, never mix Lantus or Levemir with any other solution. Be sure to check with your doctor, pharmacist, or diabetes educator before mixing. These instructions explain how to mix two different types of insulin into one shot.
