High Density Spray Foam: How Does It Compare?

High Density Spray Foam How Does It Compare

There are many different types of spray foam on offer, for use in varying applications.

To differentiate between each form of foam, its important to look at their level of density. Every density is designed for a specific task.

Today, we will look at high density spray foam insulation. Where do you install it? And what are the benefits of high density spray foam insulation.

Of course, we have to look at the other two, just so that you get a deeper understanding of the subject in question. Once you know the densities, you will be able to understand which density would best-suit your project.

High Density Spray Foam Insulation

As the name implies, this insulation type has denser structure than other spray foam insulation. That means you need more material to cover the same area of space.

More material usually means more money. Yes, high density can be costlier than low and medium density. Given the fact that there is a lot more material, the foam does not expand as rapidly as alternative types.

A professional contractor will install your insulation using a large spray truck, and an air compressor.

What are the benefits of high density spray foam? Well, for starters, you need to understand where you apply it. High density is designed for roofing and exterior insulation, and, on the whole, is appropriated for commercial projects.

For residential projects, lower density spray foam is preferable.

Medium Density Spray Foam Insulation

Medium density is the most common type of spray foam insulation. Consider this a mix between low and high density spray foam. The weight of medium density foam is 2lbs per cubic feet. 

Medium density spray foam is designed for wall cavities. This spray foam has specific benefits which depend on both the climate, and type of building you live in.

Used mostly for interior cavity fill, medium density spray foam can be used for continuous insulation as well.

But the best place to use it is in the crawlspace, where you need the highest R-value per inch as possible. In typical applications, medium density spray foam is not affected by moisture.

Low Density Spray Foam Insulation

The common name for this spray foam insulation is open-cell. The weight of this foam is just 0.5lbs per cubic feet. Low density spray foam insulation is best used for continuous insulation and air-sealing barrier. 

Apply on walls, unvented attics, ceilings, ducts, and in crawl space. Low density spray foam is impenetrable to air and moisture.

Spray Foam Insulation Advantages

You’re probably wondering, why all this talk about spray foam. Well, without a dose of humbleness and modesty, spray foam is the best insulation type around.

Spray foam offers the highest R-value among all other insulation materials. Let’s look at the few key advantages of using spray foam, including high density spray foam insulation.

One advantage that will grab your attention is saving. The cost-to-value ratio of spray foam is just insane.

Yes, it costs more to install spray foam. However, the long term savings outweigh any differences with other insulation materials.

Spray foam offers the most savings, up to 50% lower energy bills for the life of your home. Unlike other insulation types that last for 5-10 years, and need to be replaced, spray foam stands the test of time, making it a highly cost-effective solution.

The only thing we have to mention is to always look for a professional insulation contractor for your spray foam installation. Insulation is one of the few renovation projects in your home you cannot do yourself.
