Spray Foam Insulation: Conserving Energy and Improving Your Home

Insulating a home is crucial to the comfort and long-term livability of the home. It can be done in traditional ways by using fiberglass, or you can use spray foam insulation for long term insulation.

What is Spray Foam Insulation?

Spray foam insulation is a combination of two different chemicals that, when sprayed together, create a mound of foam that looks like a cream puff. The two chemicals isocyanate and polyol resin set quickly, and within minutes they are a hard mound of foam. The chemicals react with each other, expanding to over 40 to 100 times their original size and making it perfect to fill a wall cavity. 

Benefits of Spray Foam Insulation

  • Air Barrier:  When spray foam is released into an air cavity, a seal is created between the wall and the rest of the room, making the wall airtight.

  • Double the R-Value per Inch when it is closed cell:  The R-value is the amount of thermal resistance that the foam is withstanding in terms of temperature. It holds the temperature of the space consistent.

  • Long-Lasting:  Spray foam insulation does not degrade in the same way as regular fiberglass insulation. It will hold its foam and insulating capabilities for years.

  • Minimizes Condensation in the Wall Cavity when it is closed cell:  The foam barrier does not allow for the buildup of condensation in the walls as the temperature changes.

 Types of Spray Foam

  • Closed Cell: Closed Cell insulation is rigid and will remain rigid for a long time. It is also more expensive than open-cell insulation.

  • Open Cell: Open Cell insulation is a lot lighter than closed cell and has a lower R-value. It is also more affordable than closed-cell insulation.

 Disadvantages of Using Spray Foam Insulation

  • Expensive:  Using spray foam, both closed- and open-cell, is not cheap. It has higher price points than some other kinds of insulation.

  • Wait Times for Chemicals to Cure:  Using spray foam is non-toxic only after a period of time that averages around 2 to three days after spraying a whole house. The curing process produces chemicals that maybe dangerous for the lungs and may cause disturbances in vision; it is important to follow the recommended wait times.

  • Wall Cavity Exposure:  The best way to use spray foam is to completely expose the wall cavity. It means being unable to install drywall at the same time the spray foam project is conducted, thereby possibly adding a bit of difficulty in planning.

  • High toxicity in the fumes

Open Cell Spray Foam Insulation

Open-cell spray foam insulation is very light. The foam is very pliable and low density. It has an air barrier and thermal barrier. Open-cell spray foam is more permeable because of this with a very porous consistency.  

Closed Cell Spray Foam Insulation

Closed-cell spray foam insulation is denser and has a higher R-value. This makes the mixture more like glue which is an excellent barrier to air and moisture. It adds strength to walls and structure because of its density.

This hard foam is non-porous causing the cells to cling together creating a barrier between outside substances and the room.
