What Is Spray Foam Insulation Made From?

Have you ever wondered what those big white trucks are spraying into people's homes? It's insulation! More specifically, it's spray foam insulation.

But what is it, and what is it made of? This article will take a closer look at spray foam insulation and find out what it's made of.

What is spray foam insulation?

Spray foam is a type of insulation sprayed onto walls, ceilings, and floors to insulate and seal a home or building. It prevents air and heat from escaping, making it much more energy-efficient than other types of insulation.

Unlike other insulation materials, spray foam expands to fill gaps or cracks, making it an excellent choice for difficult-to-insulate areas. It also doesn't sag, compress or settle over time like fiberglass or cellulose insulation.

That's not all. Spray foam insulation also:

• Reduces noise pollution
• It's mold and mildew resistant
• Prevents pests from entering your home
• Protects your home from fire

Spray foam comes in two types: closed-cell and open-cell. While both create an effective insulation barrier, they have some key differences.

Closed-cell spray foam has a higher R-value (resistance to heat flow), meaning it's much more effective at insulating your home in Orlando. It's also denser, making it more durable and resistant to pests and water damage.

On the other hand, open-cell spray foam has a lower R-value, but it's much cheaper than closed-cell foam. It's also more breathable, making it a good choice for areas that need ventilation, like attics.

So, what is spray foam insulation made of?

The main ingredient in spray foam insulation is polyurethane. This polymer is made up of two chemicals, isocyanate and polyol resin. These two ingredients are mixed and sprayed through a nozzle, where they react and expand to create the foam. (1)

Additives are added to the mix to control the foam's density, expansion rate, and other properties. Common additives include:

• Surfactants (to help the foam expand).
• Blowing agents (to create the foam).
• Fire retardants (to make the foam safer).

Now that you know what spray foam insulation is made of, you can see why it's such an effective way to insulate your home in Orlando. Not only does it expand to fill any gaps or cracks, but it also has a high R-value, making it excellent at preventing heat loss. So spray foam is a great option if you're looking for an insulation material that will do a great job at keeping your home warm.
