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 glargine should not be mixed with other forms of insulin due to the low pH of its diluent. Use of commercially available premixed insulins may be used if the insulin ratio is appropriate to the patientâs insulin requirements. Currently available NPH and short-acting insulin formulations when mixed may be used immediately or stored for future use.
