Choosing between rigid foam and spray foam is a challenging task for many homeowners. However, our years of experience in this field shows that both foams are effective and important when giving your attic a new look. Thus, deciding between the two options shouldn’t be that difficult. By following the guidelines set by the Department of Energy, you will be able to cut your overall cooling and heating costs by as much as 50 perfect.
Effectiveness of Spray Foams
Spray foam is typically applied directly against the base of the plywood. This is basically the roof sheathing, and application is done between studs and rafters in the attic. By applying a spray foam in your attic, you will enjoy more comfort within your home while still saving hundreds of dollars every year.
A Better Alternative to Fiberglass
Most homeowners see fiberglass being displayed at hardware stores or notice that it is commonly used in most homes. Such findings make them assume that fiberglass is the most efficient and quality material for upgrading the attic. However, this assumption is far from the truth. The fact is that fiberglass has a fluffy and soft texture, just like a pillow. Such a soft texture is never effective in stopping airflow. On the contrary, insulating the attic using foam is able to stop airflow because foams do not get pressed down easily. This way, the R-value of the foam is maintained over time. On the other hand, fiberglass gets saturated and pressed down with time, thereby losing its effectiveness and R-value.
There are two types of foam that can be applied in any attic. These foams are rigid foam and spray foam. To start with, Spray Polyurethane Foam (SPF) is normally applied on the underside part of the plywood, that is under the roof, an area known as the sheathing. It is applied in its wet form and expands to form a thick foam. This way, the roof becomes fully sealed and insulated. Spray foam is also pest resistant and waterproof, making it a long lasting insulation material.
Another reliable option for insulating the attic is using rigid foam. Rigid foam is usually made of solid boards that have radiant barriers at one or either sides. This enhances its effectiveness in insulating the attic. A rigid foam can be fitted directly below the rafters or even between them. Both methods of installing a rigid foam form an envelope, thereby insulating the attic from the outside.
Enhance the Overall Value of Your Home by Insulating Your Attic with Foam
One of the best investments you can ever do for your home is insulating the attic with foam. This is also an investment suitable for homeowners who want to upgrade their attic and use it as an extra storage space. This upgrade can also convert an unused attic into a welcoming living space. Insulating your attic with foam is also advisable for homes that have HVAC equipment or extensive ductwork. Insulating an attic in a home that has HVAC equipment or extensive ductwork increases their efficiency.
