The insulation in your home plays such a large part in your home’s HVAC system. If you do not choose the proper insulation for the project at hand, you could risk energy-inefficiencies and thermal bridging. However, with the use of the right type and amount of insulation, you can increase your home’s energy-efficiency and have the ability to keep your home the desired temperature in extreme weather. 

At SumZero Energy Systems in Milford, we use a variety of different spray foam insulation, including open-cell spray foam insulation. Call our home energy improvement experts today to learn more! 


Characteristics of Open-Cell Spray Foam

The two major categories within spray foam insulation are open-cell and closed-cell. There are a few different characteristics that separate these two different types of spray foam insulation and make them the best options when used properly within your home. Call us today at SumZero Energy Systems for more information about open-cell spray foam insulation!

#1 Volume

Open-cell spray foam expands more than other types of spray foam. With that, you are able to get more volume out of the same starting amount when it is applied. While the R-value may be slightly lower than in closed-cell spray foam, applying more volume will leave you with the same R-value and offers a more economical option as long as you have the extra space that it requires. 

#2 Density

Open-cell spray foam does not have a very high density. This may be seen as a negative since it lets more air pass through the insulation—causing thermal bridging in your home. However, open-cell spray foam creates a great insulation option when looking to create a sound barrier, as the lower density allows the insulation to absorb sounds effectively, unlike closed-cell spray foam.

#3 Vapor-Permeability

Open-cell spray foam has a vapor-permeable characteristic, which means that this type of insulation absorbs and releases moisture that it comes in contact with. While this is a vital characteristic in some instances, it can lead to major water damage if not used appropriately. Be sure to take note of moisture, and the location of the insulation to ensure the right type is chosen.

#4 Air Sealing

One of the most useful characteristics of open-cell spray foam, as with closed-cell, is its ability to increase your home’s air tightness. The combination of its ability to expand and its ability to adhere itself to surrounding surfaces allows you to air seal your home to increase the energy-efficiency. Open-cell spray foam insulation is particularly good at air sealing hard to reach places.


Where To Use Open-Cell Spray Foam

  • Nooks and Crevices
    • As mentioned previously, the expanding characteristic of open-cell spray foam makes it the perfect option for those hard to reach nooks and crevices to ensure that every part of your home is air sealed and insulated.
  • Above-Ground Walls
    • Open-cell spray foam is often used to insulate the walls of a home that fit a few simple specifications. Those specifications include homes that are not located in areas of extreme weather and walls that are above-ground.
  • Attics
    • The expandability of open-cell spray foam also makes it a great insulation option for attics as it quickly covers the area and provides a great R-value as well as air sealing capabilities when two to three layers are applied. 
  • Beneath Floors
    • Open-cell spray foam can also be applied beneath flooring. In high-humidity areas, you will want to apply it in combination with closed-cell or a vapor retarder paint to prevent water from causing problems with the flooring.

Our Open-Cell Spray Foam

At SumZero Energy Systems, we use an open-cell spray foam insulation from Gaco. Our home energy improvement experts have chosen Gaco open-cell spray foam due to its high quality and versatility. This particular insulation not only contains all the characteristics listed above, but it also goes above and beyond in multiple areas.

When taking a deeper look into Gaco open-cell spray foam insulation, you will find that it is resistant to mold, which provides mold and mildew protection as moisture passes through it. This insulation, thanks to its lower density, also has a flexibility that allows it to shift and move with your house. When your insulation has the ability to move with the house, it prevents the following issues from occurring: 

  • The need for reapplication of insulation over time 
  • The possibility of compromises to your home’s air tightness
  • Cracked insulation that causes gaps and inefficiencies
  • Damage to your home’s structural make-up
