Home insulation is most important to stay safe from bone-chilling winters. Without proper insulation, you can’t survive in the cold weather. So, this is the main reason for which you need to come with proper knowledge of whether fiberglass insulation or foam insulation is best.

Fiberglass Insulation vs Foam Insulation

This is popular as one of the hot topics at the current time. Most of the people are still unclear whether they should go for fiberglass insulation or should go for foam. One thing is to keep in mind that, fiberglass insulation procedure has been adopting maximum American homeowners for decades. They are simply making their own home insulated with installing fiberglass. However, spray foam is new in this matter and people use it recently but it is gradually getting popular.

Fiberglass Insulation vs Foam Insulation

  • Fiberglass Insulation

Fiberglass insulation is all about a series of delicate fibers with different types of recycled materials. Initially, there were melted down glasses. In order to make them effective, these sheets of fiber glasses fit with the help of adhesives. These adhesives also work as vapor barriers just like reflective aluminum foil or paper. These are quite cheap and very much effective. At the present time, more than half of the Americans are using this fiberglass in their homes.

  • Spray Foam

Spray foam insulation is a certain kind of liquid chemical that always comes out in spray form and can easily expand to form with a proper airtight seal which is over the cracks. In this way, the outer air can’t trespass and it will keep your home unharmed from the outer climate. In this way, if there are any cracks in your home, they will close and there will be no airflow within them.

Once they are out of their original packaging, they can easily cover huge spaces. These are, however, able to fit exactly with the standard spacing between the attic walls and the studs.

In this way, the cells are completely closed and the cells press one another to properly block the passage of the air along with moisture. In this way, the foam stays more rigid, stable, and dense compared to the open cell.

  • Open-Cell

Open-cell comes with cells as they are not packed full. In this way, the foam becomes flexible and soft.

If someone will compare these two, he’ll find that a closed foam cell is much better compared to the open cell. It applies well where the attics are tight. Apart from it, the moisture-resistant qualities are much more user-friendly. So, there will be no way of any kind of water damage or leak issues.

  • R-Value

While going to the usefulness of insulation, it would be best to understand the R-value. This measurement is used to properly determine the effectiveness of resisting the air-flow. However, the R-Value is simple. The higher will always deliver a better result.
