How Long Does Spray Foam Insulation Off-Gas

Spray Foam Components

Spray foam is a two-component chemical process. There’s a part A and part B. Part A which is methylene diphenyl, di-isocyanate, or MDIs are the most usual components found in most kinds of spray foam. 

Part B though is made of amines, which are under research, and little is really known about these chemicals on their own. So it’s a bit of a question mark. 

Does Spray Foam Off-gas?

The first thing that might come to your mind while installing spray foam is how long does spray foam insulation is off-gas and we’re also going to touch on if it’s something that you should be concerned about? Then we would have to say that yes, there is some off-gassing. 

There are some people who are more sensitive toward odors and smells than others or might have breathing issues like asthma. Then that’s always going to be concerning. But there are a couple of things to keep in mind when considering off-gas and spray foam. 

The first thing is the re-entry, re-occupancy time after a spray foam project is done. If you use a safe premium product those time frames will be 2 to 4 hours. Some products on the market will have a much wider time frame, where we are talking about up to 24 to 48 hours for re-entry and re-occupancy. That’ll be something to consider if off-gassing is a concern for you. 

Is It Harm Full?

It’s no secret that spray foam is a cocktail of chemicals that come primarily from the oil industry. Some cocktails are different than others, so there’s good reason to be informed about what kind of cocktail you’re getting, and if spray foam is that you’re considering having installed in your home. 

The biggest potential health danger for spay foam is largely present during the installation process, which is why you’ll see installers wear full-body gear and respiratory devices. That’s because exposure to spray foam during the blowing process can bring on asthma, lung damage, skin and eye irritation, and other respiratory issues. 

Aerosols vapors and even dust from unreacted chemicals are also potential hazards. The chemicals that are used to make spray foam when are properly prepared and precisely mixed, under the right site conditions, these chemicals will have a complete reaction eventually and become inert, causing to off-gas. 

Now if that’s been done properly, you can’t just walk into your house on the day of installation as we talked about earlier here. You should wait for at least 24 to 72 hours before re-entry and make sure the space has been properly ventilated during the process. 

So if you have kids and are getting spray foam installed, we definitely recommend spending a few extra days at grandma and grandpa until the house is safe to re-enter. 

Spray Foam Environmental Impacts

We know that spray foam comes from the petrochemical industry, so that means we already know it has a very high embodied energy footprint. It’s a petrochemical product and can’t be recycled after it’s been used. 

The blowing agents that are used in the recipe are often the culprit. And there’s a measure associated with this, which is global warming potential or GWP for short.

Now in traditional spray foam, that number is actually in the thousands. And in newer spray foams though, innovation has made it possible to get that number down below five. 

Costing Of Spray Foam

Now the rumors are true here. Spray foam does typically land at the high end of the cost scale. That said, cost variance is also pretty dramatic. Usually, typical projects are somewhere in the $ 1.50 to $5 per square foot of coverage assuming an inch of foam is installed. 

Ultimately, we think some of you won’t be faced with the information provided here today. And trust that your spray foam and installer are safe and environmental footprint from installation is negligible.
