How Spray Foam Keeps Moisture Out of Your Iowa Attic

Spray Foam Used as a Vapor Retarder in Iowa Homes

Closed Cell Spray Foam Moisture BarrierWhile most insulation types are prone to retain water and develop mold issues if there is a leak, this is not the case with spray foam insulation. Spray foam insulation can actually be used to keep moisture out of your home as well as to keep it insulated. By installing closed cell spray foam on the underside of your roof, you can keep your attic dry and warm all year long.

Overall, there are many great advantages to using spray foam insulation in the attic of your home in Iowa:

  • Effectively Insulates Home
  • Reduces Moisture Infiltration
  • Eliminates Need for Ventilation
  • Prevents Mold Growth

Most types of insulation soak in water if there are any leaks in the roof. This means that they become saturated and increase the likelihood of mold growing in your home. This is just one of the drawbacks to using traditional means of insulation instead of spray foam to insulate your roof and attic.

Why Use Spray Foam Insulation for Your Iowa Attic?

Because the spray foam binds so tightly to the bottom of the roof when it is applied, it prevents the materials that make up the roof from moving during changing temperature conditions. This reduces the chance that nails will pop or loosen, keeping opportunities for water entry from the roof to a minimum. The roof may still develop a leak if the construction was poor, but the moisture will not spread throughout the entire roof as it would with a more porous insulation material like fiberglass. Instead, the spray foam will prevent the moisture from spreading and damaging the entire roof and seeping through to the ceiling.

The effectiveness of spray foam at regulating the temperature in your home is just one of the reasons to choose it as the insulation material in your attic. Not only will spray foam insulation stop winter cold and summer heat from infiltrating your home, but it will also reduce moisture and leakage from the roof. Also, the ability of closed cell spray foam to trap moisture and air out of your home means that you no longer need ventilation in the attic. Ventilation is put in to carry moisture build up out of the fibrous insulation material to maximize thermal efficiency. Since spray foam insulation does not absorb moisture, no ventilation is needed.

Air Sealing New Homes

Air Sealing a New Home

According to the Department of Energy, 40% of heat loss in a building is due to air leakage. If this is not reason enough to air seal a new home, let’s consider another idea: air leakage is air movement. Air movement carries moisture. Moisture fuels mold growth. So if you stop the air movement (the air leakage), you greatly reduce the chance for mold growth in the walls of your home.

How to Air Seal

There are many avenues you can take when considering air sealing a home. There are a few low-cost things you can do to start air sealing your home. A simple step like caulking double studs and top and bottom wall plates is a great place to start. Great skill nor expensive tools are necessary to complete this project: all that is needed is a caulking gun and a step ladder.


Keep in mind that it can take several cases of caulk to air seal a home depending on the size and how the house was framed. This is a project that anyone can do, including a prospective home buyer who is looking to save some cash. For great results, you must pay great attention to detail. This video has great ideas as to how to air seal your walls:

Window Sealing

The next step in this project would be to seal all protrusions in the exterior walls. This includes electrical boxes, plumbing, and AC lines. Any other protrusions should be sealed up and a great way to do this is with canned spray foam you can find at your local hardware store or lumber yard.

Most quality windows are sealed very well. However, when installed in a rough opening of the wall there can be a gap up to an inch. This area also needs to be air sealed. It is important to be careful when sealing these areas up because the window manufacturers have specifications as to how it should be done, and it varies from manufacturer to manufacturer. You can seal these gaps with caulking or canned spray foam.

When using canned spray foam around windows and doors, it is extremely important to utilize the proper type. There are two kinds of canned spray foam: minimal expanding (or door and window) and regular expanding. When working with windows you definitely want to use the minimal expanding canned spray foam. Using the regular expanding spray foam can cause the window frame to bow which leads to wedging the window shut, damaging it. Another important tip when using canned spray foam: be patient. Use a small amount and allow it to expand. Make several short passes and wait between applications to allow it to expand fully. Failing to do so results in using too much product and having to trim it off, resulting in wasted material.

Ceiling Sealing

The best time to seal the ceiling is after the drywall is hung. Once again, any protrusions through the ceiling needs to be air sealed (including electrical boxes, wiring, can lights, duct work, etc.). Also don’t forget bulk head areas over cabinets or chases. Canned spray foam can work well for most of these areas. It might also be required to use a foam board to cover the protruding area and then to seal around it.

For more air sealing tips, you can download this book from Green Builder Magazine.

Spray foam insulation is also an air seal. Choosing Iowa Spray Foam to install open or closed cell spray foam in your new home can seal up many of these areas mentioned in this blog and more. Open or closed cell spray foam insulation finds all of the cracks and gaps the wall or ceiling areas may have.

Basement Insulation and Moisture Management

Basement Insulation and Moisture Management

There is a widely spread misconception even in today’s construction of new homes that people believe they don’t need to insulate basements. There are many reasons why basements need to be insulated.

Why Insulate a Basement?

Some people believe that because a basement is typically protected and surrounded by dirt that the dirt will insulate the basement. Think about it this way: during the winter the frost line can be anywhere from two to four feet deep. The dirt surrounding the basement is not completely up to the bottom of the siding. Up to six foot of the basement wall is below 32 degrees Fahrenheit: basically 75% of the outside of the basement wall is below 32 degrees Fahrenheit. If it’s 32 degree outside wouldn’t you wear a coat? This is the equivalent of insulating your basement walls.

Most basements are about the same equal exterior wall area as above ground walls. So if you don’t insulate the basement over half of your exterior wall is not insulated. Interestingly enough, it takes about four feet of dirt to equal the same R-Value of a two inch thick piece of foam board.

Moisture Management

For most people it does not occur to them the moisture that is in a home is due to a “dry” basement. They are misled to believe that homes have a “dry” basement. Many new homes never get a vapor barrier. To learn more about vapor barriers, visit this blog post.

Most people believe concrete to be waterproof but this is not true. In fact it is exactly the opposite: while it may not let water in it allows capillary water transfer. According to EnviroShield, “Moisture problems are not necessarily caused by hydrostatic pressure. Concrete is hydroscopic: like a sponge it will absorb moisture from the air and if the humidity on one side of the concrete differs from the other, it will move moisture to the drier side.”

The video below will give you a good explanation as to where to install your vapor barrier and capillary breaks. It also gives you a good overview of different ways to insulate a basement:

Insulating Basement Walls

Basement walls can be insulated inside or out. But also keep in mind that you will need an air barrier. One of the biggest issues with insulating the outside of the basement comes from having to attach the insulation to the concrete wall. Another large problem occurs when attempting to protect it from damage when backfilling the basement over dig. A main concern for many home owners is that insulation on the outside of the basement is not aesthetically pleasing.

Therefore, your best option is to insulate from the inside. There are a variety of options to choose from: you can attach a foam board to the wall or hang vinyl-backed fiberglass rolls from the rim joist area down. The fiberglass method has become the favorite for the “Economy Production Home Builders” you see now. The fiberglass rolls are often called “diapers” in the construction world because they look like diapers and have a tendency to absorb water in the same manner.

vinyl backed fiber glass basement

The last way to insulate the basement is to stud it up like an exterior wall would be and install batt insulation or spray foam insulation. This is the best way to insulate the basement wall. If you install fiberglass insulation in the basement you will need to be sure to control moisture in the concrete. If moisture is not controlled the perfect environment for mold growth is made.

The simplest and most recommended way to insulate a basement wall is with closed cell spray foam insulation. To learn more about the specifics of closed cell spray foam insulation, visit this link.


Closed cell spray foam insulation is an air barrier, a vapor barrier, a drain plain, and insulation all in one simple step. It solves all of these problems in one. Wood foundation basements can also really benefit from close cell spray foam insulation.



Many home basements are not insulated. When finishing a basement this is a great time to insulate it. Give Iowa Spray Foam a call and let us help you insulate your basement with closed cell spray foam insulation.
