If you are looking to insulate your house or a commercial building, the benefits of spray foam insulation are worth looking into.

Even though this type of insulation is generally more expensive than other types, the long-term benefit of foam spray insulation is that it can actually save you money on your bills.

They are two different types of spray foam insulation to consider. Depending on your needs, you can pick from the open cell or closed cell spray foam.

What is Spray Foam Insulation?

Spray foam is an insulation product that is commonly used in older buildings, such as the Baxter Hotel in Bozeman.

The basic principle behind spray foam is that it is coated onto an existing concrete or asphalt slab.

This type of insulation has existed for decades and it can withstand high temperatures.

This insulation is safe and can help decrease your energy bills while improving the energy efficiency of your home.

Spray foam insulation is designed for regular walls. It does not have foam coating so the quality can vary from product to product.

What Spray Foam Insulation Does

As you have probably figured out, spray foam insulation is a spray material.

The spray foam material is compressed air that is stored in a tank. The compressed air is sprayed on the wall or on a flat surface. The air displaces the surrounding air so it doesn’t have a chance to settle.

When the spray foam is used to insulate a wall, it is made into small “blobs”. Those blobs are only a few hundred microns in size. They are only 10% of the size of air molecules.

As the air is forced into the walls, it lifts any junk in the surrounding air. That causes the material to expand.

Who Should Use Spray Foam Insulation?

These foam insulation systems work great for long-term applications and should be used by anyone who plans on living in their home for the long term.

They do have drawbacks when used for shorter or temporary projects. Some of the disadvantages include:

  • Lack of consumer support in the form of competition among companies.
  • It is more expensive for contractors to install spray foam.
  • Because of the lack of consumer support, the barriers to entry are extremely high. The warranties are often only for the manufacturer, and not the supplier.
  • A main issue for consumers is that the trade is regulated through several different agencies. This can make it difficult to contact the manufacturers directly.
