With the use of rigid insulation homeowners in the northern areas of the country are able to combat heat loss through their attic. The rigid insulation is a foam polystyrene material that comes in various thickness to add to the current R-value of the fiberglass insulation between the rafters. One of the most common thicknesses of rigid foam insulation is 3/4 inches. The installation process is very straightforward and easily done by any do-it-yourselfer. Since the rigid insulation is the same dimensions of drywall, the installation is very much the same.
Place the insulation back onto the rafters and screw it into place. Use 2 1/2-inch deck screws to secure the rigid insulation to the rafter. Place some 1 x 3 blocks along the insulation to keep it in place without any bowing or bending. here
Use a straight edge along the line where you want to cut the rigid insulation. Place a hard, flat surface under the insulation to give it some stability for a cleaner cut. Run a utility knife along the straight edge with several cuts. here
Rigid foam insulation offers as much as double the R-value of traditional fiberglass batts, according to the United States Department of Energy. This additional R-value boosts your home's thermal resistance, keeping valuable heat indoors in the winter, and unwanted heat energy outdoors during the summer. Choosing the right insulating rigid foam can help you keep energy bills in check, reduce your impact on the environment and maximize the comfort of your home.
Extruded polystyrene (XPS), also known as blueboard, acts as the best insulating foam board for below-grade applications, according to the U.S. Green Building Council. XPS offers greater moisture resistance than EPS, without the need for special films or coating to fend off moisture. It's also stronger and denser than expanded polystyrene foam, with an R-value of 5 per inch. here
The U.S. Green Building Council calls polyisocyanurate (ISO), or polyiso, the most eco-friendly foam insulation. Not only does this material contain at least nine percent recycled content on average, it also contains a flame retardant that's much less toxic than flame retardants used in other foam insulation. With an R-value of 6.5 per inch, polyiso offers greater thermal resistance than other rigid foam products. ISO is the most expensive of all rigid insulation materials. Because of the tendency of polyiso to absorb water, this material should not be used for below-grade applications. here
One of the main factors affecting R value is the density of the material. Many forms of insulation, such as fiberglass blankets and blown-in cellulose, are made of loosely woven or packed fibers. Rigid insulation, on the other hand, is usually made of substances that can be fused together more compactly, increasing the density of a comparable single layer. This increased density is one of the primary reasons a rigid insulation R value is often higher than that of many other forms of insulation. For example, on average, rigid insulation R values are at least twice that of similarly sized fiberglass blankets and at least one and a half times that of comparable amounts of blown-in cellulose. more
Insulation is designed to help keep buildings warmer when it's cold by keeping heat inside, and cooler when it's warm out by keeping hot air out. The ability to reduce the flow of heat is typically represented by a positive number called an R value. In general, the higher the insulation R value is, the more the material keeps heat from moving from one side to the other.
One of the main advantages of rigid insulation having higher R values is the ability to use less. For example, if a person wanted to have R-15 insulation in his or her attic, but only had limited space to add it, some rigid polyiso foam options could allow for using just 2 inches (5 cm) of insulation, as compared to the typical 4 to 5 inches (10 to 12.5 cm) of fiberglass or cellulose insulation that would otherwise generally be required.

Rigid insulation is typically a hard foam material that is used to help regulate the temperature in buildings. The thermal resistance of this material, or effectiveness at keeping heat from passing through, is known as rigid insulation R value. In general, rigid insulation R value is higher than that of other materials used as insulators. This typically makes it a more efficient choice, although it can also add to the cost.
