Green board: When and where? - GreenBuildingAdvisor
2019年1月20日 · I have also spent time ripping out failed green board during remodels. The worst mis-use of the material was a sad bathroom with tile applied directly to greenboard with a latex based adhesive. Worse, the job was not the result of a mis-informed weekend warrior. The general lack of water and mold resistance was also reflected in the non-tiled ...
Drywall: Traditional, Greenboard, DensArmor Plus, Aqua Tough
2018年11月5日 · Greenboard has only one face that is mold resistant, it’s not the entire sheet that is different from regular drywall. I use green board in skylight wells as a little extra protection against problems caused by condensation, But I wouldn’t trust it as serious mold proofing if you have substantial moisture issues.
Schluter Kerdi on regular drywall - GreenBuildingAdvisor
2018年6月30日 · I'm going to use the Schluter Kerdi system for my shower, mainly because it's less work and seems more fool proof than the traditional mortar bed. Prior to this, I always considered waterproof drywall a must in the bathroom. The manufacturer says regular drywall is fine because the Kerdi membrane is waterproof. Looking for opinions, would waterproof drywall behind Kerdi membrane be insurance ...
Bathroom Walls, Mold, Vapor Barriers, and Building …
2010年7月8日 · But I do somewhat agree that kraft-faced insulation is not a good insulation for around showers and the like. Mold will feast off of any kind of paper if it gets wet and stays wet. Furthermore, I have demolished a bathroom where greenboard drywall with moldicide has been completely covered in mold which is not supposed to happen.
What type of board in bathrooms - GreenBuildingAdvisor
2010年9月21日 · Greenboard (MR drywall) in bathrooms (requires 16" oc ceiling framing) and backer board on tiled surfaces. In areas with uncontrolled moisture or wicking moisture (such as sub-grade concrete walls), non-paper faced drywall is wise. There's already too much cement in a typical home and no need to use it for wall board as well.
Backerboards – Winners against Water - GreenBuildingAdvisor
2010年12月24日 · Greenboard + 2 layers of paper + 1" of mud seems like an awful lot of effort when 1 sheet of Durock with taped & mudded seams will do the trick. Plus, you're introducing cellulose (mold food) into your system and relying on the other layers to keep it dry.
Densarmor vs greenboard level of risk - GreenBuildingAdvisor
2021年7月11日 · Running a dehumidifier for entire space at 60%. Ready to pick up drywall. I have worked with regular drywall before, actually learned through a q and a on this site. Greenboard is 15 bucks a sheet at box store, they have a drywall supplier that has densarmor plus for 28 a sheet, it’s about a 35min drive.
Permeability of drywall primer and sealant - GreenBuildingAdvisor
2020年1月20日 · Hi all — I regularly see drywall described as vapor permeable if it’s painted with latex paints. This is normally viewed as a good thing if there’s an impermeable barrier on the exterior side of walls – we’re advised against having impermeable barriers on both sides of a wall because it can trap moisture and cause mold.
What’s best Sheetrock to use in basement? - Green Building Advisor
2023年11月18日 · The paperless drywall (e.g. DensArmor) is an excellent product, but because of the fiberglass face, it needs to be skim coated if you want a typical smooth finish. I have it in utility areas of my basement where the additional texture is not a problem. To clarify one thing mentioned, DensArmor *does* have beveled edges.
Ceiling Drywall Screw Spacing - GreenBuildingAdvisor
2016年12月11日 · Hi all, Currently have 1/2" drywall secured to the ceiling with nails every 12". Going to be pulling out the old fiberglass batts up there since it's mostly destroyed and covered in mouse droppings. My plan is to just cover it with blown in cellulose. Can anyone recommend how far apart I should add extra support screws to reach about R60 in the attic? I know standard spacing for screws is 12 ...
