What is Spray Foam Insulation?
Spray foam insulation is a popular choice for keeping buildings warm and energy-efficient. It’s made from polyurethane, known for its great thermal and air-sealing abilities.
Overview of Spray Foam Insulation
Spray foam insulation is a special mix that expands and hardens after it’s applied. It fills gaps and creates a tight seal, stopping air leaks and saving energy. Unlike other insulations, spray foam fits perfectly into any space, ensuring full coverage.
A Brief History of Spray Foam
Polyurethane, the main part of spray foam, was created in the 1930s. But it wasn’t until the 1980s that it became a key insulation option. Over time, it has gotten better, with new ways to use and improve it.
Now, spray foam is used in many places, like homes, businesses, and even cars. Its ability to save energy and last long has made it a favorite among builders and homeowners.
How Spray Foam Insulation Works
Spray foam insulation makes your home more energy efficient and strong. It’s made from a special mix that turns into a solid, tight seal.
Chemical Composition & Reaction
The secret of spray foam is in its chemicals. The “A” side, with MDI and pMDI, meets the “B” side, full of polyols and more. This mix expands fast, filling every space.
R-Value and Thermal Resistance
Spray foam’s R-value is a big plus. Closed-cell foam, in particular, is very good at keeping temperatures steady. It needs to be at least 2 inches thick in walls and 3 inches in roofs to meet energy standards.
This high R-value means your home stays comfy all year. It also cuts down on energy bills.
Density and Structural Benefits
Spray foam is not just good for keeping warm or cool. It’s also strong. Closed-cell foams, being dense, act like glue, making buildings stronger. They also help block out sounds, making your home quieter.
| Spray Foam Insulation Property | Benefit |
|---|---|
| Chemical Composition & Reaction | Rapid expansion and air-tight sealing |
| R-Value and Thermal Resistance | Excellent temperature regulation and energy efficiency |
| Density and Structural Benefits | Structural adhesion and sound dampening |
Types of Spray Foam Insulation
There are two primary categories of spray foam insulation: open-cell foam and closed-cell foam types. Each type has its own benefits and uses. Let’s explore the main differences between these two types of cell spray foam insulation.

Open-Cell vs. Closed-Cell Foam
Open-cell spray foam is lighter and more flexible, with a density of about 0.5 lbs/cubic ft. It starts at an R-value of 3.6 per inch. This makes it perfect for filling interior walls and unvented attics. It also helps with sound absorption, adding to its acoustic benefits.
Closed-cell spray foam, on the other hand, is denser, with a density of 2 lbs/cubic ft. It has a higher R-value starting at 5.7 per inch. This makes it great for exterior and roofing applications that need more insulation power. It also acts as a strong air and vapor barrier, reducing energy costs and strengthening the building.
Key Differences Between the Types
- Open-cell spray foam is less expensive to install, with material costs about 30% lower than closed-cell.
- Closed-cell spray foam provides a higher R-value per inch, making it more efficient for insulating tight spaces.
- Open-cell spray foam is better suited for sound dampening, while closed-cell excels at adding structural integrity.
- Closed-cell spray foam can act as a vapor barrier, while open-cell cannot for below-grade projects.
Which Type Is Right for Your Home?
The choice between open-cell and closed-cell spray foam insulation depends on your project’s needs. Consider the climate, R-value requirements, and the areas being insulated. Talking to a professional spray foam contractor can help you choose the best type for your home.
