less soundproof? Or will it be better with some kind of insulation + drywall? Maybe layered drywall? Does quietrock (?) go with drywall? Also, we're not opening up the entire wall along the length of the house. I believe the wall right now is plaster/sheetrock, and my dad (and contractor) has mentioned putting in drywall. ![]() I've looked through this sub for recs and understand it won't completely soundproof the house, but right now when they cough next door it sounds like they're in my unit so I think any improvement on that will be welcome on both sides. I also edit audio from home so am very sensitive to sound. I'm more concerned about noise than temperature control since we're not touching the exterior-facing walls. I think it might be worth opening the living room and bedroom walls too, and putting in soundproof insulation. We're doing some renovations soon that will require opening up the kitchen wall. It's a two-unit shotgun and they're mirror images, so my tenants next door and I share a common wall the length of the house. I recently moved in to my ~100yr-old home and I know the walls are not insulated. I've never heard of greenboard sagging in ceilings as long as it's fastened at the recommended intervals.Hey all. I would do anything that might get wet or splashed with greenboard.in a 7'x7' I think that'd be all of the walls. ![]() My current acrylic surround (direct mount to stud) goes up to about 6' and is greenboard above that, it appears have weathered 7 years of showers just fine (I should be able to comment on this fully in a couple of weeks when we tear it out so we can put tile up). If water gets to the middle of the greenboard, it will stay inside and bad things will happen. Greenboard paper is water-resistant, but the gypsum inside isn't. A plaster wall won't want to take the pin and will probably splinter. Most plaster wall homes have some spider cracking in the walls. You can use greenboard or drywall for the other walls and latex paint will probably save you from soaking. Push a thumbtack or pin into the wall in an inconspicuous spot to test its hardness. You can usually tell immediately when walking in to a house. Tub or shower surrounds can only be greenboard or drywall if you are putting schluter kerdi membrane or similar waterproofing on it, although IRC says that surrounds need to be cement board or fiberglass or similar products (durock, densshield, hardi-backer). Also other things that can dramatically increase time and cost is how the plaster was hung. Here's my take on it (also referring to the IRC codebook): greenboard is for walls that might get splashed but not sprayed. This is because plaster is old and can be very brittle you will lose control of a powerful sawzall and just the vibration can cause large section of plaster to be ripped from the wall. I have been getting ready for a bathroom reno and doing a lot of research as well. Right now I'm leaning towards using it on the walls which come in contact with the shower and the rest with regular sheetrock. ![]() Some say to use all regular sheetrock with a few coats of paint and that would be just as effective. I've also heard that I need it on walls behind the shower. I've heard not to use it on ceilings as it will sag. ![]() My question is, where do I need greenboard, if at all? There is a bulk head which goes right down the middle of the bathroom which has furring strips for the framing to try and keep it a comfortable height. There is a 4 piece shower in the corner fastened to the studs. I figured it might be best to get an opinion for my case in particular. From my many searches, I'm seeing many different opinions and even many different quotes from the 'code'. I had always planned about buying all green board but I figured I would see what the internet thought about it first. I'm about to go buy drywall for the bathroom I'm adding in my basement.
