To become an insulation contractor, graduate from high school, complete a training program, and obtain licenses and certifications. Insulation contractors typically work indoors, although they may occasionally work outside insulating oil or gas lines.


Home insulation is vital to saving energy, cutting costs and helping the environment. Caulking to attic insulation to finding places that need more insulation are efforts that can keep a home and wallet comfortable.


The four main types of home insulation include loose-fill insulation, rigid board insulation, reflective insulation and blanket insulation. The materials used for home insulation works include cellulose, foam, fiberglass and radiant barriers.


Before you start a home insulation project, ensure you have the appropriate materials and equipment on hand. Safety glasses, gloves and a dust mask are essential when working with fiberglass insulation in unventilated areas. Keep the area clean and organized, and stage materials for each room ahead


Oil, fur, silk, wool, rubber, glass, plastic, wood, paper, wax and ebonite are good insulators. Insulators are substances with tightly bound outer electrons and heavily resist the flow of electrons. Most nonmetals are classified as insulators.


The most accessible and affordable home insulator is rolled fiberglass, and the most effective insulator is closed cell foam, according to HGTV. Cotton batts are a comparable option.


Materials that make good insulators do not have the ability to conduct electricity, such as glass. They insulate because they do not have enough free atoms to conduct electricity.


Some examples of insulators are glass, plastic and rubber. Insulators block the flow of electricity through them due to the stability of the electrons surrounding an atom. However, the electrons in some insulators, such as glass, move more freely in extremely high temperatures and can become conduct


General contractors make approximately $28.55 per hour or an annual salary that ranges between $27,000 and $119,000 including bonuses, according to PayScale, as of 2015. Salary varies according to location and length of time in the position.


Insulation slows or prevents heat, sound, electricity, mechanical vibration or radiation from coming through walls. There are four types of insulation: heat insulation, sound and vibration insulation, electrical insulation, and radiation insulation.
