The method of controlling the application of a foam insulation wherein a resin and a foaming agent are pumped through separate lines into a mixing chamber and the mixture injected into a receiving area, the method including the steps of automatically adjusting the rate of flow passing through each line to compensate for changes in said flow whereby the resin and foaming agent are continually moved into the mixing chamber in the same proportions, maintaining the temperature of the resin and foaming agent at a constant level, monitoring the air temperature in the receiving area, and automatically changing the temperature of the resin and foaming agent in the event the air temperature moves outside of a desired range.
