OverviewSynthesis and reactionsApplicationsGreenhouse gasPhysiological effects and precautionsSee alsoFurther readingExternal linksSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling) is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly solublein water but quite soluble in nonpolar organic solvents. I…

Installing Insulation. The maximum thermal performance or R value of insulation is very dependent on proper installation. Homeowners can install some types of insulation notably blankets and materials that can be poured in place.Types of Insulation. Type. Material. Where Applicable. Installation Methods. Advantages. Blanket: batts and rolls. Fiberglass. Mineral (rock or slag) wool. Plastic fibers.Blanket: Batt and Roll Insulation. Blanket insulation the most common and widely available type of insulation comes in the form of batts or rolls.Concrete Block Insulation. Concrete blocks are used to build home foundations and walls, and there are several ways to insulate them. If the cores aren't filled with steel and concrete for structural reasons, they can be filled with insulation, which raises the average wall R value.See full list on energy.govHow Home Insulation Helps Reduce Your Energy Bill This thisoldhouse/insulation/21097080/home insulation...Dec 05, 2019The EPA estimates that the average homeowner can save 15% on heating and cooling costs (11% of total energy costs) by adding insulation in attics, crawl spaces, and basement rim joists. For most folks, that's about $200 in savings per year. In colder parts of the country, like climate zones six and seven, savings increases up to 20%.
