Is Foam Insulation Safe?

Are there any harmful chemicals in the foam that will affect the well-being of your home and those living in your household?
Is Foam Insulation Safe

Your home is a refuge from the outside world. A place to relax from the stresses of your day, to feel comfortable and be with those you love. A place where you feel safe. 

If you are thinking about foam insulation for your home, a question that may have crossed your mind is, “Is foam safe?” Are there any harmful chemicals in the foam that will affect the well-being of your home and those living in your household? These are both good questions and ones you need answers to before you have foam insulation installed in your home.

If you have done some research on foam, you have probably run across some terminology like “off-gassing,” “volatile organic compounds” (“VOCs” for short), and “re-entry time.” But what do all of these terms mean? And how could they potentially affect you? In this article, I will break down the meaning of these terms and explain how they are related to the products that RetroFoam of the Carolinas offers.

Terminology Defined

Let’s talk about terminology for a minute before we get into how the terminology relates to the products.


Simply put, off-gassing “is when products release particulate matter and gasses that were formerly trapped in a liquid or solid form.” Do you know that “new car” smell that people love? That is a product of off-gassing. Off-gassing can happen with many household products such as carpet, paint, toys, mattresses, electronics, and insulation. Scientists have learned a lot about off-gassing but are still learning about all of the effects.

Volatile Organic Compounds

Volatile Organic Compounds, commonly referred to as VOCs, are the product that is produced by off-gassing. When a product off-gasses, it releases VOCs.

Re-Entry Time

Re-Entry Time refers to the amount of time you will need to wait before you re-enter your home after installing your foam insulation.

Injection Foam vs. Spray Foam

RetroFoam of the Carolinas offers both injection foam and spray foam. Both types of foam provide similar benefits but are very different products with different installation processes.

As stated in our blog, “Spray Foam And Injection Foam; Why You Need It And What’s The Difference?” spray foam is “the perfect solution to seal and insulate all at once for open spaces like attics, crawl spaces, and unfinished walls. It is an excellent choice for new construction as well as metal buildings and pole barns.” 

RetroFoam’s injection foam is injected into your already built walls. This allows you to update your insulation without having to do major renovations. 

Let’s talk about the off-gassing of each product. RetroFoam (the injection foam) does not off-gas. It is also non-toxic and will not be corrosive to pipes or wires in your walls. (see the RetroFoam Tech Facts here)

On the other hand, Spray foam does off-gas, but don’t let that deter you. Be aware, not all spray foams are created equal. When selecting a spray foam, you want to make sure you choose one with low VOC. This means that the foam you choose is one of the safest options. It is also important to pay attention to re-entry time. Some spray foams don’t allow for re-entry for up to 48 hours. This means that there is going to be a lot of off-gassing. RetroFoam of the Carolina’s spray foam is a low VOC, and the re-entry time is around two to four hours.
