Hi my name is Paige and on behalf of Expert Village, today we are talking about redoing my office. I’m working with Amelia who is an engineer and also Craig Hale who is an interior designer. The first thing I did was sit down with Craig and discussed different things that I needed to do and what I wanted out of my office. The first step is to blow insulation. I have an older house and I have replaced windows in here before so I know there is no insulation in these walls. So we are going to blow insulation. The first thing we did was to drill holes in our wall. I got this bit here and from just a local hardware store you put it into your screwdriver and then find an area in between your studs. Now in this house, it is an old house so you can actually see where the studs are. If you have a newer house and you need to blow insulation, you can use a stud finder. So in between every stud, we’ve drilled this hole we are going to then fill it with insulation. I am going to be blowing insulation into this room and the first step is to shut off the power in the room that you are working in, find the studs and mark your spot between the studs where you want to cut your hole. We have a hole cutting drill bit that we have attached to just a standard hand held drill. You want to do it high on the wall because when you are blowing insulation you are going to work with gravity and gravity is going to allow the insulation to fall. If you put it low, the blower has the ability to blow upward some but after you start filling the wall it won’t be able to lift the entire stack of insulation anymore. Put the hole pretty far up on the wall but not so far it will be hard to catch the hole. You want a little room to move your spackling knife later around the hole. You should wear a dusk mask when cutting a dry wall.
