In the vast world of home insulation, there are an increasing number of options to choose from. From traditional fiberglass and cellulose to spray foam, the material you choose to insulate your home is only one factor among many others to consider. In exploring your spray foam options, you may find yourself asking: “What is wall injection insulation?” Well, if you are facing this query, the DFW Thermal Solutions team is here to provide some answers!

What is Injection Foam?

Simply put, injection foam is a resin solution mixed with a foaming agent that transforms into an insulating substance when combined with compressed air. Once these two components are mixed together with compressed air by professional metering and pumping equipment, they form into a shaving-cream-like substance. After being injected into the cavity, this foam expands to fill it and maintains its shape and thickness within the cavity permanently.

How is it Installed?

When injecting insulation foam into existing walls, a professional crew will start by drilling a hole next to the stud, about 4 feet up the cavity. Then, using a slim Jim to measure the space between a second stud, they will drill another hole. Once all cavities have been drilled, a foreman will begin to inject the foam into each cavity. To avoid a mess cleanup, another technician will typically clean up the excess foam as the foreman injects the cavities, filling the drilled holes with a Styrofoam plug. Following behind is usually a crew that mops away wood shavings and foam from the siding and ground. If you hire an efficient crew, the installation process should move as smoothly as an assembly line to keep the project moving and messes to a minimum. Typically, this process can take from 3-5 hours, with an additional 24-hour drying period.

Does Wall Injection Insulation Work?

As you might know, most energy waste is the result of air leaks, which lead to the infiltration and exfiltration of air. In other words, during summer months, air leaks allow your cool indoor air to escape, while letting in unwanted heat from outside. Conversely, during winter months, air leaks allow your heated air to escape and cold air to enter your home. In both cases, your HVAC system will be forced to work overtime to compensate for the energy loss, causing your utility bills to increase significantly. Furthermore, these leaks can allow dusty or moldy air from your crawlspace or attic to enter your home. Because the spray foam used in wall injection insulation not only provides an air barrier, but is also water-resistant, it can effectively kill two birds with one stone. That is to say that wall injection insulation can keep unwanted moisture and mold growth out, while keeping warm or cool air in for the most comfortable indoor climate, year-round.
