Spray foam insulation is an excellent air barrier that can save homeowners a lot of money in the long run. It seals gaps, cracks, and other areas around a house to prevent moisture from leaking inside. Moreover, it's also a great way to keep heat from escaping your home.
However, it's important to be aware of the risks associated with spray foam. Specifically, you need to be aware of the potential for the off-gassing of hazardous chemicals. This can cause eye, nose, and skin irritation, and can even lead to respiratory issues.
The EPA recommends avoiding spray foam for at least 72 hours. During the initial curing process, the foam will off-gas a lot of volatile organic compounds (VOCs). The VOCs are 3,400 times more potent than carbon dioxide. Since these emissions are not filtered out by a ventilation system, they can become dangerous.
As a result, the EPA considers the safety of spray foam to be questionable. In addition, many manufacturers include multiple hazard data sheets in their spray foam literature. These lists can be more than 84 pages long. Some of these lists contain references to toxic chemicals, such as benzene, methylene diphenyl diisocyanate (MDI), and formaldehyde. There is also a high global warming potential (GWP) for some of these agents, meaning that their release into the atmosphere is a significant contributor to global warming.
The use of wholesale Spray Foam to insulate homes has been around for a while. It's commonly used to insulate homes in crawl spaces, knee walls, and rim joists. Additionally, it's been used to insulate attics.
Unlike cellulose and fiberglass, which tend to shrink or break over time, spray foam doesn't. Instead, it expands and hardens, creating an airtight barrier. Aside from saving money on heating and cooling, spray foam can also protect your lining from a variety of hazards. For example, it can deter pests from eating through your wall, and it can help reduce sound transmission.
But before you can start using spray foam, you need to choose the right type. It is important to know the difference between the open-cell and closed-cell types of material. Closed-cell foam is more expensive, but it provides a strong vapor barrier and is stronger. Open-cell spray foam is much cheaper, but it does not offer the same strength. You might also be tempted to use more than one type of spray foam to make sure you get a good combination of features.
If you decide to use spray foam, you should hire a professional to handle the job. Regardless of whether you're installing it yourself or having it done by a contractor, you will need specialized equipment to perform the task. Also, it's best to avoid applying this substance in your attic or other areas that are not well-ventilated. Otherwise, you can be exposed to hazardous off-gassing, and you may not be able to fully appreciate its benefits.
Although spray foam insulation has been in use for decades, it's not known to be safe for humans. It's important to take precautions and follow the guidelines provided by the EPA, the US Department of Energy, and other organizations.
