Choosing Between Closed-Cell And Open-Cell Spray Foam

One of the challenges of fiberglass batt insulation is that the insulation is difficult to fit in all portions of your home. A better option is to use spray foam insulation, which can fill the small gaps that other insulation options wouldn't fill. Unlike other options, spray foam won't shrink or settle over time, will fit hard-to-reach places and will reduce sound transmission through walls. There are two main types of spray foam insulation to choose from: open-cell and closed-cell. There are also several factors you need to consider when choosing which type you will use.

How Much of a Budget You Have

The primary benefit of open-cell insulation is that it is inexpensive. If you do not need the insulation to provide additional stability for your home and if the climate your home resides in is mild, you may be better off choosing open-cell insulation. But regardless of the cost, you will save money overall because you will not have to rely on your HVAC unit as much.

Both types of insulation are usually added using a truck. If the job is somewhat small, there are disposable canisters that can be purchased that cost hundreds of dollars. For the smallest jobs, an aerosol can can be purchased for $5 containing the spray foam.

Your Home's Stability

While the primary purpose of insulation is climate control, spray foam insulation can also strengthen homes and protect them from the downward pressures that are caused by standing rain water and snow. Homes with adequate insulation are also more resistant to wind.

If you want spray foam that contributes to the stability of your home, you will need closed-cell insulation. The spray foam adheres to a surface and produces a gas that causes a dense wall of bubbles that contributes to the stability of your home. The closed-cell insulation is also easier to install. The open-cell insulation needs to be installed by a contractor, such as High Country Insulation.

Heat Insulation vs. Sound Insulation

Open-cell only insulates about half as much as closed-cell. However, if you simply add more open-cell insulation to a wall cavity, you can achieve the same level of insulation. However, open-cell insulation insulates against sound better than closed-cell.

Weather Considerations

For extreme weather conditions, closed-cell insulation is ideal because it blocks heat all-year-round. Also, if you live in a very humid area and are concerned about water absorption, closed-cell will create a better barrier that will help keep your home drier. But regardless of which option you choose, your home will be better off by having spray foam insulation added.
