As the weather begins to chill, many homeowners begin to have questions about what the best insulation is for their attic – loose fill or spray?
Do not be intimidated by the cost or what you don’t know about spray foam insulation. It actually outperforms and outlasts other types of insulation, including loose fill. Let’s begin with answering a basic question: What exactly is spray foam insulation?
Spray foam insulation is actually a combination of two materials – polyurethane and isocyanate. When these two composite materials are mixed together, it causes a chemical reaction that creates foam, which expands and hardens to provide a protective barrier in your attic.
There are actually two types of spray foam insulation. Open-cell spray foam insulation is denser and spongier to the touch than closed-cell spray foam insulation. Open-cell spray foam insulation also provides an effective sound barrier and will help quiet your home and is less expensive than the closed-cell type of insulation.
Here are some of the reasons why spray foam insulation the best choice to insulate your attic from winter’s cold and summer’s heat for a number of reasons.
Due to its expansive nature, spray foam insulation is a strong insulator that tightly seals the nooks and crannies in your attic that loose fill insulation simply ca not. Due to its ability to tightly fill the smallest holes and cracks in your attic space, spray foam insulation creates a seal that is 24 times less susceptible to air infiltration than other insulation.
It also acts like a glue and adds to the strength of the walls in your attic and roof, making them less likely to sustain damage during a high wind event like a hurricane or other severe storm. It is also easier and quicker to install than loose fill insulation. It takes just one application to install, does not settle like loose-fill insulation.

Spray foam insulation can also help keep your home free of harmful mold and mildew. Water can gain access to your attic through holes and cracks you might not know even exist. Spray foam insulation can’t be penetrated by water and forms an effective barrier against moisture. Spray foam insulation will also not attract such pests as bugs and mice.
In addition to being water resistant, spray foam insulation is made up of an inert polymer that does not attract mold or mildew.
Spray foam insulation has a lifespan of at least 20 years, meaning that you will enjoy cost savings and not have to re-insulate for about two decades. It is also nontoxic, is ecologically friendly and comes with a lifetime guarantee.
Since it grows to about 100 times its original volume, it will also expand and contract as your home expands and contracts.
