I'm new to this community so I apologize if I'm not doing this right. I'm located in North Carolina where the temperature was 17 the other night. My laundry room is exposed to the outside on 3 sides and the washer/dryer are side-by-side on one of the walls and the dryer exhausts out this same wall. Also on the outside attached to the siding on this wall are my utilitiy boxes, fuse box, and AC runoff PVC piping and AC connections. Silicon flexible caulking is around the dryer vent and AC connections on the outside but the draft still persists inside coming from under the washer/dryer across the floor. This is a single story townhouse on a slab and I'm thinking more insulation needs to be added to this wall. Everyone I've talked to says the sheet rock would have to be removed to add more insulation because of the existing studs. I am interested in learning about alternatives and hopefully less expensive ideas. Can anyone help me?

Like the sliding door doesn't meet the top of the frame or something[ATTACH]76387[/ATTACH]. Not sure what type of weather stripping to use as the sliding door will be opening and closing obviously. I tried to draw an example on the computer since im at work. hope you get an idea of what im talking about.
