Spray foam insulation is one of the most common types of insulation used in homes and businesses. It is available in various colors, but most people choose white or light-colored foam for their projects.

Does colored spray foam have different characteristics than white foam? There is no significant difference between colored and white spray foam in insulating properties. However, some believe white foam is more aesthetically pleasing than colored foam.

If you are considering using spray foam insulation in your home or business, you should continue reading this guide.

Does Color Affect Spray Foam Performance?

Spray foam is available in a few different colors. But what has color got to do with heat transfer?

The color of the foam does not affect its R-value. The R-value is a measure of how well the material resists heat flow.

It’s the same with white and black foam. The difference in color won’t make one better than the other at resisting heat flow. In fact, most spray foam colors have an R-value of around R-3.5 to R-4 per inch.

The difference in color is due to the binding agent the manufacturer has used. The binding agent is a resin that helps the foam to cure and gives it strength. It also determines the color of the foam.

Some companies add pigment to their binding agent to produce different colors. That’s why you will see some variance in color from one brand to the next.

What Are The Available Spray Foam Colors?


The most common color for spray foam is white. It’s also the most popular color among homeowners.

Many people choose white because it looks neat and tidy. It also has a brightening effect, making rooms seem more open and airy.

If you want to achieve a clean look, white is the way to go.

Light Gray

Light gray is another popular color for spray foam. It’s a neutral color that can complement any d├ęcor. Gray’s calming effect makes it a good choice for bedrooms and other relaxing spaces.


Like light gray, beige is a neutral color that can go with almost anything.

Beige foam has a warm, earthy look that can make a space seem more inviting. Beige is a good choice if you need insulation for a large space. It can help to make a room feel cozy.


While it may seem overwhelming, black spray foam is becoming more popular. Some people choose black because it has a modern look. It can also make a space seem more dramatic.

Rosy Beige

If you’re looking for a slightly different foam, Rosy beige foam is a good option.

It has a pinkish hue that can add a touch of warmth to a space. The color is perfect for nurseries and other child-friendly spaces. However, it might fade over time if exposed to direct sunlight.

Forest Green

Some brands also make forest green spray foam. The deep, rich color can add a touch of luxury to a space. It’s perfect for creating an opulent look.

However, it’s important to note that forest green foam is not as standard as other colors. Therefore, you might have trouble finding it if you’re not looking in the right place.

Blue and Purple

Both blue and purple spray foam are relatively uncommon. However, they can be fun colors if you want to add a pop of color to your insulation. 

Does Spray Foam Color Affect Its R Value? 

The color of spray foam doesn’t affect its R-value, which measures how well the material resists heat flow. Moreover, color does not affect the longevity or durability of the material either.

Therefore, you won’t experience any difference in terms of heat transfer if you choose white foam over black foam.

The color of the foam can affect its appearance, though. The most popular choice among homeowners is white foam because it looks neat and tidy.

Black foam can make a space seem more dramatic, while blue and purple foam can add a pop of color.

Will Spray Foam Color Change or Fade Over Time?

If spray foam is exposed to direct sunlight, it starts to deteriorate in just 72 hours. When that happens, the color also fades away.

In fact, if spray foam is under direct sunlight, it will degrade by 1/16th inch per year. So that means that if you have 2-inch thick foam, it will only last for 16 years.

It’s also important to note that some colors absorb more heat than others. For example, black foam absorbs more heat than white foam.

That means black foam will degrade faster than white foam if exposed to direct sunlight. You can use an elastomeric membrane to protect your foam from UV rays and extend its lifespan.
