Today spray foam insulation is increasing in popularity. However, before, you can decide to install it, it is important to have prior knowledge about spray insulation to see if it suits your needs.

Why is Insulation Important?

Foam insulation is best installed during a home renovation project however, even if you are not planning on remodeling or renovating your home or commercial space any good insulation contractor in Palo Alto, CA can install it at any time.

The main purpose of insulation is to reduce the loss of heat. Insulation helps to keep your indoors warm during the winter, but cool during the summer. There are many different types of insulation that you may choose from; however, foam insulation is among the best. When installed correctly, it helps to reduce the buildup of moisture and condensation indoors, it helps to increase comfort levels, and more importantly, it helps to reduce your energy bills.

What is Spray Foam?

Spray foam or polyurethane is a type of insulation that is composed of two chemical components. These are known as polyol resins and isocyanates and are commonly referred to as ‘A’ and ‘B’ in the industry. When these two chemicals react with each other, they combine to form spray foam.
When sprayed, spray foam increases quickly, up to 30 times in size, and takes the shape of the area that it is sprayed into. Foam insulation was invented by Otto Bayer and it became very popular in the 1970s. Subsequently, two types of foam that are open-cell and closed-cell spray foam insulation were developed and are currently used today. Insulation contractors in Palo Alto, CA install both types of foam insulation. 

Defining R-value

When researching foam insulation, you may have come across the term R-value. R-value may be defined as an insulation material’s resistance to heat. If the R-value of an insulation material is higher, it has much better resistance to heat.

All insulation materials have an R-value. Cellulose has an R-value that ranges between R-3.12 and R-3.8 whereas fiberglass batts have an R-value that ranges between R-2.9 and R-3.8. Closed-cell spray foam on the other hand has an R-value between R-6 and R-7. On the other hand, open-cell spray foam has an R-value between R-3.6 and R-3.9. Before you choose to install foam insulation, speak to your insulation contractor in Palo Alto, CA.

What Affects R-value?

The amount of R-value that your home or commercial building needs depends on where you live. Naturally, warmer places require a lesser R-value than colder places. Different areas in a home will also require different R-values. For instance, the R-value in your attic will differ from the requirements for the R-value of your walls. R-value depends on the type of insulation that you choose, the temperatures outdoors, and the way in which the installation is installed.

When it comes to spray foam insulation, it is true that it has a high R-value. Apart from this, it is the only insulation that helps to create a complete air seal. Therefore a good insulation contractor in Palo Alto, CA will concentrate on creating a complete air seal as well as achieving the recommended R-values for your building codes.

Areas Where Spray Foam Insulation Should Be Avoided

Foam insulation can be used almost anywhere, however, it should not be installed in certain areas. Read on to find out more about where insulation contractors in Palo Alto, CA recommend not using it.

Near ceiling light boxes

Foam insulation may catch fire when it is sprayed too close to ceiling light boxes because foam insulation traps heat. Always contact your insulation contractor in Palo Alto, CA, to find out more details about using this insulation near ceiling lights.

In enclosed spaces

Foam insulation is also best avoided in areas that are too tight. Instead of using foam insulation, you should use injection foam between studs, and in enclosed cavities of brick exteriors.

Between exterior walls and electrical boxes

Spray foam insulation is best avoided near electrical boxes because it can easily enter the box and jam up the parts. There is also the possibility of a fire so all good insulation contractors in Palo Alto, CA will avoid this area.

If you have respiratory illnesses

Spray foam insulation off-gases for the first few hours after it is first installed. Therefore, if you have respiratory illnesses or allergies, you should stay away from the area where it is being installed. Once it cures, it is non-toxic in nature, and you will not have issues. Always speak to your insulation contractor first before you choose to install this type of insulation.

Is Crawl Space Insulation Important?

You may be wondering whether crawl space insulation is really necessary. The crawl space is the area between the main floor and the foundation of your home. When spray foam insulation is installed in the crawl space, it helps to lower energy bills and prevents cold air from entering your home from below. Other benefits of crawl space insulation are that it prevents moisture buildup; helps to keep pests and rodents out and it also prevents drafts.

Depending on the type of crawl space that you have, your insulation contractor in Palo Alto, CA will either need to insulate the underside of the floor or the crawl space walls. If there is ductwork in your crawl space, then only the outside of the walls will be insulated, but if there is no ductwork, then the underside of the floor will be insulated.
