Insulation

A material used to prevent or inhibit the conduction of heat, sound, or electricity. Electrical wires are coated with waterproof plastic or rubber coatings to protect against moisture or water, which can act as a good conductor. Building insulations are used to slow down the transfer of heat through walls to provide comfort by maintaining a uniform temperature, and to reduce energy costs. Heat transfers are reduced in homes and buildings through the construction of double walls or hollow tiles lined with thermal insulation materials. Soundproofing, on the other hand, provides acoustic insulation or the reduction or elimination of sound intensity.
