Spray Foam Frequently Asked Questions

What if I already have some insulation in my walls?

The other great benefit of using injection foam is that it can be injected into walls that have underperforming insulation. It will completely encapsulate old fiberglass batt insulation or other insulation products, that you may already have in your walls that are not performing. It provides a complete seal and does not settle or deteriorate like fiberglass or cellulose insulation. Play our installation video to see how this works.

How much heat is lost through my walls, windows, and doors?

Typically, the proportion of the total amount of heat loss is estimated to be approximately 50% through side walls (due to air leakage), 25% through ceilings and attics, and 25% through windows and doors.

How does an installer know when my wall is full?

Pressure and temperature gauges in our equipment are used throughout the installation progress. As the empty cavity becomes completely filled, a small amount of back pressure is produced. Once this pressure reaches a point, as monitored through the gauges, the installer stops the injection and proceeds to the next access hole. In addition, an experienced installer knows the time it takes to fill a specific size and shape cavity. If the pressure reaches the completed level before the normal fill time has elapsed, a blockage may have occurred, and additional access holes are drilled above or below the blockage. Our installers are trained and certified installers of injection foam.

What is the anticipated energy savings from Injection Foam?

Typically, energy savings are up to 30 to 50% of your energy costs. Unlike most investments in your home, the savings from insulating your walls will actually pay for the investment, over a three to four-year period.
