Spray foam insulation is a popular form of insulation that you can apply as a liquid that hardens later to form insulating foam. You can spray it onto surfaces, such as walls, ceilings, and floors, to make your home airtight and improve the energy efficiency of your home.

Spray foam roof insulation has a lot of benefits such as reducing energy bills, creating a comfortable atmosphere in your home, and maximizing the shelf life of your roof. You can also install spray foam insulation over your existing roof. However, take the help of a professional before you spray this on your roof.

How Spray Foam Insulation Works

The spray foam insulation traps air in small bubbles that help create an insulating barrier to keep your home warm in the winter season and cool in the summer season. Thus, it helps save a lot on your energy bills.

How to apply Spray Foam Insulation?

You can easily apply spray foam in closed spaces so that it does not allow the air to escape through the walls. You can use it on your roof, attics, crawlspaces, and on the floor. You should avoid using spray foam in basements as there will be a lot of moisture in that space.

Benefits of Spray Foam Insulation

Spray foam insulation has many benefits such as:

  • It works as a firm seal to help keep out drafts and other elements that cause a poor indoor atmosphere.
  • Spray foam insulation increases the energy efficiency of your home and thus saves a lot of bucks. In simple terms, you need less energy for the heating and cooling systems of your home.
  • It acts as an insulating barrier and is thicker than the other forms of insulation available on the market. Hence, it ensures a more comfortable indoor atmosphere compared to other types of insulation.

Benefits of Spray Foam on your roof

If you use spray foam on your roof then it will help maintain the ideal temperature in your home. When insulation is installed outside of your home, it gets colder at night to resist the heat flow. This way, you can keep your home warm in the winter season and cool in the summer season.

Spray foam is different from other forms of insulation as it can seal the smallest leaks in your home efficiently. Hence, it is capable of reducing indoor air pollution and also preventing drafts. So, with spray foam insulation, you can save your electricity bills up to 20%

Types of Spray Foam Insulation

Spray foam insulation is available in three forms such as open-cell, closed-cell, and low-density spray foam insulation.

Open-cell Spray Foam insulation:

This type of spray foam insulation consists of small cells that are not closed completely, which helps increase the density of the insulation and keeps your home more protected than other forms of insulation. This type of spray foam insulation is affordable and is very much popular among homeowners. However, it has low R-value than other forms of spray foam insulation. Hence, it might not be so effective in preventing heat loss in your home. Open-cell spray foam can be best used in your attics and crawl spaces.

Closed-Cell Spray Foam insulation

This type of spray foam consists of cells that are close to each other, which makes the foam denser thereby preventing the air to pass through it. Closed-cell spray foam keeps away the heat from the building and thus makes the indoor atmosphere pleasant. It is very much energy-efficient. You can use this type of insulation anywhere in your home and is ideal for the exterior walls of your home.

Low-density Spray Foam Insulation

Low-density spray foam is dense than open-cell spray foam and has s higher R-value than other forms of insulations. It is also more capable of preventing moisture formation in your home compared to other types of insulation. It is ideal for exterior application.

What is Icynene Spray Foam?

Icynene spray foam insulation consists of small open cells and can expand 100 times faster than open-cell spray foams. This type of spray foam insulation has an open and breathable structure. It is low-density spray foam insulation; meaning it has a lower R-value compared to other types of insulation. However, you can still get excellent air sealing properties with Icynene spray foam insulation.

Icynene spray foam is one of the most challenging forms of insulation that you should install with the help of a skilled expert. You can inspect your insulation after a few years of installing it to detect if it needs a replacement or repair.

Icynene spray foam can last up to 50 years. However, the shelf life of spray foam insulation depends upon certain factors like the climate and environment in which you have installed it as well as the type of spray foam you have used for your home.
