First in a Series: Benefits of Open-Cell Spray Foam

← Back to List
You may be considering spray foam as an insulation option. However, you might be confused. What are the differences between open-cell spray foam and closed-cell applications? In this first in a series on spray foam insulation, we’ll take a look at open-cell spray foam.

Both open and closed-cell spray foam insulation involves the application of polyurethane products.  You may already be familiar with the virtues of polyurethane. When it comes to sealing air, it is invaluable. Polymers are activated by heat and strengthen into place. The flexibility of using a foam product makes it conducive to most environments.

However, there are differences between open-cell and closed-cell applications. We will first discuss how open-cell spray foam might work for your job. In our next article, we will review closed-cell spray foam insulation.

When Should You Consider Open-Cell Spray Foam

First, let’s examine the types of businesses that may have an overall use for spray foam insulation. They include:

  • Building Contractors

  • Home Builders

  • Roofers

  • Plumbers

  • Electricians

  • HVAC Contractors

Spray foam insulation is an excellent solution for a variety of reasons. Air seepage is a major concern. Drafts are too often responsible for rising utility costs. The effects extend further. In addition to combatting air leakage, there is also the thermal advantage. You might not think of one other factor, but it is another consideration. Spray foam insulation makes it harder for insects and rodents to intrude premises.

But, what about open-cell spray foam insulation? When is it preferable to use this product?

First, it’s important to understand what open-cell spray foam actually means. It is also known to be low density. One of its advantages is that it allows for some flexibility when used to combat air seepage or insulation. You may also hear open-cell spray foam referred to as half-pound foam. This reference concerns the product’s weight. When measured in relation to cubic feet, it is a half-pound per square foot. The R-value, or resistance to heat flow, is estimated to be somewhere between 3.5 to 3.7 per inch.

You might think of spray foam insulation as a means of plugging up the holes and strengthening overall construction. It can be sprayed into open cavities or onto joints. Seams can be hardened with spray foam insulation so that building shifts do not cause them to drift them apart.

Open-cell spray foam insulation offers advantages. It is a means of creating a sound barrier. It is also mold resistant.  It is an affordable solution to reducing energy costs and pays for itself.

When is open-cell spray foam the preferred products? Before you decide on your own, you may want to seek expert consultation. Since it offers protection against mold and mildew, open-cell spray foam is ideal for attics and basements. However, you may also want to use a vapor retardant in some application situations.
