The main functions of insulation in your home are temperature control and sound insulation. There are many different types of insulation each with different R-values. R-value refers to the thermal resistance offered by the insulation product. The higher the R-value of an insulation product the greater resistance against heat or cold it offers. R-value not only depends on the quality of the insulation material but also on proper installation. Some types of insulation, such as fiberglass blanket insulation or loose fill insulations can be installed by the home owner with relative ease. Other insulations projects notably spray foam insulation require special equipment and expertise.
Here are some insulation materials and there applications.
Blanket Insulation: Comes in bats or rolls. Made of fiberglass, mineral wool, plastic fibres, and natural fibers. Used to insulate unfinished walls, floors and ceilings. Blanket insulation is fitted between joists, studs and beams before being covered with a finishing material such as gypsum panels.
Foam Board or Rigid Board Insulation: Made of polystyrene or polyurethane. Foam board insulation is applied to unfinshed walls, basement walls, floors, ceilings and unvented low-slope roofs. After its’ installation Foam or rigid board insulation is covered with gypsum panels for interior jobs and with a weatherproof facing for exterior jobs. Foam or rigid board insulation have a high R-value relative to their thickness.
Loose Fill and Blown In Insulation: Comes in large bags. Made of cellulose, fiberglass and mineral wool. Used to fill cavities in unfinished and opened walls or floors or can be blown into existing finished walls or floors through a small hole. Also used in attics and other hard to reach places. Loose fill or blown insulation is good for adding insulation in irregularly shaped areas and around obstructions.
Sprayed Foam Insulation:Sprayed foam insulation comes in small spray cans or can be applied using large pressure sprayers for bigger insulation projects. Sprayed foam insulation is usually made of polyurethane, contentious and phenolic. Sprayed foam insulation can be used to insulate unfinished attic floors, open cavities and to insulate existing enclosed walls. Sprayed foam insulation is good for adding insulation around obstructions and to existing finished areas.
Rigid Fibrous or Fiber Insulation: Made of fiberglass or mineral wool. Used in ducts and unconditioned areas. Rigid fibrous or fiber insulation can withstand high temperatures.
