Loose Fill Insulation Blown-in/loose fill insulation being installed in an attic as the official statement says. Usually made of fiberglass or cellulose (recycled paper fiber).Blown or sprayed into place with pneumatic equipment.Ideal for hard-to-reach areas such as attics.Can fill wall cavities and installed over existing insulation.
Insulation Batts Person wearing protective gear installing insulation batts in a wall.Pre-cut sections of fiberglass or rock wool insulation.Designed for easy handling and use between framing, such as studs and joists.Available either with or without paper or aluminum foil facing.Can be used in floors, walls, attics and ceilings.
Insulation Rolls Person wearing protective gear installing insulation rolls in an attic.Available in pre-cut widths to fit between studs and joists.Come in continuous lengths ranging from 20 to 40 linear feet.Ideal for attics, floors and other areas where longer runs are needed.
Foam Board Insulation Person marking a sheet of foam board insulation.Rigid panels of insulation.Can be used to insulate almost any part of your home, from the roof down to the foundation.Polystyrene and polyurethane are the most common types of materials used in making foam board.Sheathing reduces heat conduction through structural elements like wood and steel studs.
Spray Foam Insulation Person spraying foam insulation around a pipe.Latex or polyurethane spray foam insulation is sprayed into place with a spray can or specially designed equipment.Can be used to fill small gaps and cracks.Ideal for sealing around doors, windows and vents.Sets quickly and can be trimmed or painted by an exterior and interior painting contractor.
Vapor Barriers House wraps and kraft-faced insulation are examples of vapor barriers that help control the amount of moisture that passes through the insulation.
If moisture from either direction is allowed to build up within stud or cavity walls, the heat-conducting moisture will cause the insulation to lose its R-value and mold and rot will set in over time.
Vapor barriers are most commonly used when framing the exterior walls of a house.
