When homeowners struggle with heating and cooling issues, they often think that replacing or upgrading their HVAC system is the only possible solution to their problem. Unfortunately, a new HVAC system may not be the most efficient solution, especially in homes where insulation quality or quantity is a suspected issue. For this reason, many HVAC industry professionals are now working to help homeowners understand the potential importance of bolstering insulation as part of a comprehensive solution for achieving a more comfortable, efficient home environment. 

Solving air leaks can reduce the need for a larger HVAC system

Inefficiencies in home heating and cooling systems, especially in older homes, are often related to the existence of air leaks that allow heated and cooled air to transfer through the envelope of the home. Homes that experience this problem are likely to be much more difficult to heat and cool, even when the size of the HVAC system was sufficient for the square footage of the home at the time of installation.

Finding ways to solve existing air leak problems by upgrading the insulation is often a faster, more affordable solution than one that involves purchasing and installing a larger HVAC system. With its ease of installation and high R-values, spray foam insulation products can be an excellent option for resolving existing air leaks and bolstering the efficiency of an existing HVAC system. 

Two types of spray foam insulation

When first introduced to the idea of using spray foam insulation as a means of solving air leaks and bolstering HVAC performance, many homeowners are unaware that this product is available in both closed cell and open cell formulations. While both are capable of providing excellent insulation R-values, closed-cell is likely to be the better choice for use in an existing home because it does not permit water vapor to pass through. 

As the name implies, closed-cell insulation has fully enclosed cells that form an airtight seal whereas open-cell spray foam insulation has open-cell structures that allow some movement of air or water vapor. As spray foam insulation cures, closed-cell spray foam insulation will harden and form a firm exterior surface while the open cell type will form a softer surface. 

Adding spray foam insulation to an existing structure should be done under the supervision of a trusted HVAC service such as Comfort Zone Foam Insulation which can ensure that proper ventilation and humidity levels are maintained throughout the home.
