Flexible insulation is the most extensively used insulation in residential housing. This soft flexible material is made from fiberglass and is commonly used in floors, walls, ceilings, and roofs. It can be purchased by the roll and cut to length for stud cavities or rolled out to length in attics. You can also buy Velux skylights, roof windows, & sun tunnels online via JR Store.

Batts can also be purchased and are pre-cut for easy handling when insulating ceilings or crawl spaces. Both styles are made to fit traditional 16 or 24-inch framing and can be purchased with or without a vapor barrier. Flexible insulation is effective in all types of climates and is easy to install.
Rigid Foam Board Panels
Foam boards are rigid panels that are widely used for insulating foundation walls or under concrete slabs. Panels can also be applied over exterior wall sheathing when installing new siding to increase the r-value of the wall. On cathedral style ceilings, panels can be installed below the sheathing on a roof. Foam board insulation comes in rigid panels 2 to 4 feet wide, and 8 feet in length.
This form of insulation is an ideal type to use when insulating areas that are difficult to reach. It's an effective insulator to use in truss cavities or in areas containing pipes, wires, or ductwork. Loose-fill can be purchased in bags and poured into the cavities, or it can be blown-in professionally using pneumatic equipment. Blown-in is a popular method used to insulate older homes without the worry of removing any interior finished wall surfaces.
