You may be referring to the myelin .
Nerve impulse is an electrical current, which flows across the axons. So most of the neurons are surrounded by myelin sheath. This sheath gives insulation to the axons. Brain can not function without this insulation.
Insulation is a building material. It begins with the letter i.
Some services that Johns Manville provides are : manufacturer and marketer of premium quality building insulation, commercial roofing, roof insulation, and speciality products.

blown in insulation. Some of this insulation, you may have to request it. It is recycled from newspapers and other thing. It insulates better and you are being green at the same time.
Schwann cells are known as white matter that wrap themselves around some axons.
The mixture of axon types contributes to variety of responses generated. Specifically, the rate with which a response is made can vary.
Loft insulation primarily reduces heat loss by conduction. It works by trapping air in the material, which slows down the transfer of heat through the building's ceiling. Some insulation materials may also help reduce heat loss through convection by preventing air movement within the insulation layer.
Schwann Cells wrap themselves around some axons forming white matter.
Loft insulation is generally not classified as inflammable, but its fire resistance can vary depending on the material. Many types of insulation are treated with fire retardants to reduce the risk of combustion. However, some materials, like certain types of fiberglass or mineral wool, are more fire-resistant than others. It's essential to check the specifications of the insulation material to understand its fire safety rating.

An insulator is a material through which some kind of energy - usually electricity, or heat, or sound - does not easily pass.
