Tried searching on the forums, but didn't see anything about this in the last little bit, so decided to start a thread. I am in the process of looking to re-up attic insulation and will likely go with fiberglass or cellulose. I have a toddler and baby in my house and wanted to ensure I prep the house well before the contractors come in and have a thorough clean up plan after they're gone. My main concerns are the fiberglass that's in the air and on surfaces after the contractors go. 1. What's the best strategy to ensure my toddlers or even myself won't be breathing this stuff in. 2. If the contractors do a good job, should there be minimal or next to nothing escape from the blower or attic? 3. Since the attic opening is in my walk in closet in the master bedroom, should I put plastic tarp/covering all over that room to ensure fiberglass doesn't get on anything like the clothes or bed? 4. If above is done, will removing the tarp cause the fiberglass on them to just go back in the air? 5. Having all the above, if the answer is, yeah tough luck there's no way about it, I'm probably going to lean towards cellulose just for health and safety concerns. Thanks in advance for responses!

We have a built-in entertainment center / cabinet on an exterior wall. There is a gap between the drywall that is maybe a 1/4" at the bottom of the cabinet and 1/8" towards the top. The gap is open on one side of the cabinet (see attached picture). There is a noticeable draft from the bottom and sides of the cabinet, and I believe it is because there is an electrical outlet, cable outlet, and speaker wires run through the wall into the back of the cabinet (see attached pictures). The electric is in a blue plastic wall box, the cable and speakers are in metal low voltage brackets. The space between the studs where the speaker wires and cable jack run is only partially insulated. I can't see what's behind the blue electric box. For the cable and electrical wall plates, they are attached to the cabinet, not the drywall so there is a gap where air from the wall cavity can get behind the cabinet. The speaker wire bracket was just completely open. There is a gap under the cabinet bottom the bottom molding and the cabinet overhang as well. I plugged that with foam backer which seemed to have mostly stopped airflow there. I then used metal tape to try to create a seal between the low voltage brackets and the cut outs in the cabinet. I didn't do this with the electric box since I wasn't sure if it was OK to to use metal tape there. I then temporarily covered the missing speaker wall plate with some painter's tape (I have a speaker wire plug wall plate on order). The inside of the cabinet is now a little better, but there is still a noticeable draft coming from the side of the cabinet. I'm guessing the tape either didn't seal the space between brackets and the cabinet or there is still a lot of air coming out of the electrical box (or both). I'm sure the lack of insulation doesn't help as well. I'm not really sure the best way to try to address this. I was planning on cutting some pink fiberglass insulation to fill up the area currently missing insulation. However, I don't really have any ideas on how to seal the space between the drywall and cabinet back where the wall plates are mounted. If there isn't a good way to seal there, I could enlarge the holes in the cabinet to try to mount the wall plates directly against the drywall. It wouldn't look as nice, but it's not that visible. I'm also going to caulk between the side of the cabinet and the wall. If I seal the side of the cabinet maybe it doesn't matter if I seal the area between the drywall and cabinet where the outlets are? Any suggestions on the best way to try to seal and insulate?
