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).
SC: May mix with NPH insulin. Draw NovoLog into syringe first. Inject immediately after mixing. May dilute with Insulin Diluting Medium for NovoLog to 1:10 (Uâ10) or 1:2 (Uâ50) concentrations. CSII: Do not dilute or mix with other insulins. IV: Do not mix with other insulins. CSII: Change inj site at least every 3 days and reservoir at least every 6 days.
