Different Types of Spray Foam Insulation and Their Benefits

Spray foam insulation is a unique type of product that can be applied on-site. This allows the insulation to conform to surfaces with ease. To achieve the best energy efficiency, spray foam allows for a tight building envelope. If you are looking for insulation options for a construction project, this quick guide will provide you with some information on the advantages of spray foam. Keep reading to learn more.

What Is Spray Foam Insulation?

Spray foam insulation is a type of foam sealant that can be used in homes to achieve maximum insulation. This keeps the home more comfortable and also helps save on energy costs and usage. Spray foam insulation is created by mixing certain liquid components. These liquids react when they are mixed and then exposed to air. The liquids must be mixed on-site because of the sudden and powerful reaction they experience.

Once mixed, the liquids expand when they make contact with a surface. This creates a foam that can insulate the area. This foam can also seal up gaps and be used to form an air, moisture, or vapor barrier.

Why Do People Choose Spray Foam?

People choose this insulation option because spray foam is versatile and seals up wall cavities, exterior walls, crawlspaces, attics, and small gaps wherever they are found in the house. Spray foam is also useful to limit air infiltration and air movement through a structure. This can improve the overall energy usage in a structure. It can also help to limit the entrance of pollutants and allergens.

Are There Different Types of Spray Foam?

Different types of spray foam can be used for different applications. Each type offers its own unique advantages. Let’s look at these different types and their applications.

High density – This type of spray foam insulation is often used for exterior applications. It is very useful in roofing applications as well. If you are wondering is high density foam insulation the best option, you will need to speak with a construction professional and discuss the uses of the insulation in order to make the best choice.

Medium Density – Medium-density spray foam insulation is often used in instances where continuous insulation is needed. If you are wondering what is medium density foam insulation used for it could include interior wall cavities and unvented attics.

Low Density – Low-density spray foam insulation is also used for interior wall cavity fill and unvented attic spaces.
