When installation is complete, the holes are sealed with a plug and thesiding is replaced and touched up if necessary to match the wall. With so many molecules bonded together, the potential space between them is smaller, thereby preventing any flow of electricity. An insulator is a substance in which electrons cannot move from one atom to another. The liquid foam expands very slowly, reducing the chance of damaging the wall from overexpansion. The insulator will get damaged by a puncture. These materials represent a significant fraction of petroleum. The internal electric charges of these electrons, held tight together, cannot flow freely. Electrical insulation materials are available in a broad range of thicknesses, hardness, densities and colors.

In existing structures, installers remove a strip of exterior siding, usually about waist high; drill a row of three-inch holes, one into each stud bay, through the wall sheathing; insert a special filler tube to the top of the wall cavity; and blow the insulation into the building cavity, typically to a density of 1.5 to 3.5 lb. Depending upon the size and orientation of the air space, this can add another R-2 to the overall thermal resistance. Low-density foams are sprayed into open wall cavities and rapidly expand to seal and fill the cavity. The company is family owned and highly values relationships often going beyond the call of duty to help a customer. The first step in that direction is using insulators as a barrier between the power source and people. Most thermal drift occurs within the first two years after the insulation material is manufactured, after which the R-value remains unchanged unless the foam is damaged. Insulators have higher resistivity and most common insulators are non-metals. Garolite G-7 withstands temperatures up to 425 F higher than any other grade of Garolite.
