Hi, this is Jon and in this clip we will be filling our gaps. If we take a look at the inside of our door, we do have some gaps that we need to fill so that we don't get any air coming through there. To fill our gaps we are going to be using a spray insulating foam. Now this particular foam is specifically designed for windows and doors. Now we are just going to come in around any openings around our door and we will squeeze the trigger and that's going to fill it full of foam. And the foam will expand over a couple of hours, so you don't need to fill it completely full.
