Foam insulation is highly recommended by any insulation contractor in St. Helena, CA, and is definitely worth the cost because it helps to cut down on energy bills, adds to structural integrity, prevents moisture in a building, and creates a complete air seal. When installed in the attic, you will notice that your energy bills are decreasing significantly. Foam insulation may also be sprayed in the crawl space to prevent cold drafts, pests and rodents from entering. Let’s take a look at the types of foam insulation, the cost of spray foam, and whether it is necessary to use a vapor barrier.

Types of Foam Insulation

There are two types of spray foam. These are open-cell and closed-cell. Most insulation contractors in St. Helena, CA are well equipped with installing both types of spray insulation. Even though they are similar, they come with some distinctions that set them apart.

  • Closed-cell foam is relatively more expensive compared to open-cell spray foam.
  • As the term suggests in open-cell spray foam, the cells are not completely encapsulated, and they are left slightly open. This makes it flexible and malleable compared to closed-cell foam.
  • In closed-cell spray foam insulation, the cells are completely closed and it is semi-impermeable, so very little water and air can pass through it.
  • Open-cell foam is semi-permeable and it allows more water and air to pass.
  • Open-cell spray foam expands more than closed-cell. Open-cell also absorbs sound waves and can be used as a sound dampener in rooms. Thus, if you want a home office, or a home theatre, installing open-cell spray foam in the walls would be a good choice.
  • Another significant difference between closed-cell and open-cell spray foam is the difference in the R-value. The R-value of open-cell spray foam is between R-3.5 and R-3.6 per square inch. Whereas the R-value for closed-cell ranges between R-6.5 and R-7 per square inch.

Both types of spray foam are good, and it does not mean that one is better than the other. If you are confused about which one to choose, speak to your insulation contractor in St. Helena, CA, to help you make the best choice. You may even choose a combination of both types. For instance, you can use closed-cell spray foam in your crawl space, but open-cell spray foam in the walls.

Cost of Foam Insulation

One of the most important questions that you may want to ask your insulation contractor in St. Helena, CA is how much your insulation project will cost.
There are different factors that you must take into consideration when it comes to the cost. Installation costs range from $1.5 to $4.5 for labor for both open and closed-cell spray foams.

Open-cell costs between $0.45 and $0.65 per board foot, whereas closed-cell costs between $1.5 and $4.9 per board foot.

Labor costs may differ based on individual insulation contractors in St. Helena, CA and it may include service for the entire project but keep in mind that additional costs include removal of the old insulation materials, preparation, and set up and the final cleanup after installing foam insulation.

Mold remediation (in case you have mold in your home or commercial building) is an additional $1000-$3500, this is because you will have to remove the mold before applying spray foam on it for insulation cannot be applied directly on the mold.

An insulation contractor in St. Helena, CA will also advise you that another factor that affects the cost is whether foam insulation is being installed in a new home or an existing old home. In a new home, the walls, crawlspace, attic, and other areas are very easily accessible but in an older home, the siding may need to be removed and some part of the drywall may need to be torn down. This may cost additional money. Finally, the thickness of the foam insulation also affects the cost. When more spray foam is required, it will naturally cost more.

Does Foam Insulation Need a Vapor Barrier?

Traditionally, when cellulose or fiberglass insulation was used, usually a moisture barrier was needed to prevent any moisture from entering the home. Vapor barriers were generally installed to cut down on costs by preventing moisture from entering. But it was later discovered that vapor barriers often cause more harm than good. It may cause damage to the walls in a home and can make the house “sweat”. As a result, moisture gets trapped on the walls and this may lead to issues like mold. Vapor barriers may not be required in all conditions, but they are advised by some insulation contractors in Saint Helena, CA.

Vapor barriers may be recommended especially in extremely cold or hot areas when a vapor barrier is needed to prevent any moisture from entering the home. But if spray foam insulation is being installed, a separate vapor barrier will not be necessary because the spray foam insulation acts as a vapor barrier by itself.

Only spray foam insulation creates a complete seal and serves the purpose of a vapor barrier, thermal, insulator, and air barrier all at once. But keep in mind that when open cell foam is installed, it may need a vapor barrier. Therefore, speak to your insulation contractor in St. Helena, CA, for more advice regarding whether you should install a vapor barrier with spray foam insulation, to keep up with local building codes.
