1/4-Inch Drywall: The thinnest of all the options, 1/4-inch drywall is most commonly used as a skimming material. Mount it over an existing layer of wall to refresh the look and hide old blemishes. It's ideal for walls with a subtle curve to them.
Common drywall thicknesses are 1/4-inch, 1/2-inch, and 5/8-inch. The thickness required for each application is dictated by the building code. Thicker drywall may be required code for any surface covered with a texture or skim coat where studs or joists are spaced 24 inches on-center rather than 16 inches.
The thinnest wallboard is ¼ inch, which is used primarily on curved walls.
Gypsum Panel offers a lightweight drywall that scores and snaps with minimal dust for a hassle-free cleanup. This panel features a 1/2 in. tapered edge for cleaner-looking joints, providing a panel that is simple to install. Because this gypsum panel is so light, it can be easily toted around the jobsite or home.
The most common thicknesses of drywall are 1/4″, 3/8″, 1/2″ and 5/8″. In most homes you will find 1/2″ on the walls and 5/8″ on the ceilings and 5/8″ in the garage. Some homes may have 5/8″ throughout and some may have 2 layers of 1/2″ drywall. So, the thinnest drywall I believe is 1/4″ thick.
The minimum thickness of exterior walls in one-story buildings shall be 10 inches (254 mm). The walls shall be laterally supported at intervals not exceeding 24 feet (7315 mm). The minimum thickness of interior load-bearing walls shall be 8 inches (203 mm).
One key difference between the two is that sheetrock is a brand name of drywall made by the United States Gypsum Corporation. Another difference lies in their production process; sheetrock has a slightly denser core than drywall due to the addition of a small amount of wood fiber to the gypsum core.
According to drywall maker USG, a 4 x 8-foot sheet of Sheetrock brand UltraLight Panel weighs 12 pounds less than a conventional sheet, for a total of just over 39 pounds.
¼-inch drywall – the thinnest kind available – isn't as commonly used as other thicknesses because it's more fragile than thicker boards. On the other hand, it's considerably lighter and more flexible than other kinds of drywall. That makes it a good fit for curved surfaces where its flexibility is an advantage.
In certain cases, putting new drywall over old drywall is a cost-effective and speedy way to refresh a room. A few of the advantages of putting drywall on drywall include: It's less extensive than tearing out and replacing existing drywall. It can help soundproof a room.
Drywall Thickness
Panels are available in four drywall thicknesses—5/8-inch, 1/2-inch, 3/8-inch, and 1/4-inch. (above are all 5/8-inch). Each drywall thickness has specific applications and framing requirement. The 3/8-inch and 1/4-inch panels are only available in shorter lengths.
While drywall alone can hold about 1.6 pounds to 2 pounds per square foot, mounting an object to the stud with the proper hardware allows the drywall to support up to 100 pounds.
Green Board Drywall – An excellent choice for kitchens, bathrooms, basements, and attics, green board drywall is mold resistant and typically comes in 1/2-inch or 5/8-inch thicknesses. A thick layer of green paper is applied to the surface of the gypsum, and a wax coating is applied over the paper.
Without enough space when this happens, you'll get cracks. Keep a 1/8-inch space between sheets during installation to keep this from happening.
Lightweight drywall is about 25% lighter than the traditional option, which makes it easier to install, carry, and transport. In turn, standard drywall tends to have more options when it comes to thickness and fireproofing.
What's the difference between PURPLE drywall and traditional green drywall? Traditional green drywall (also known as greenboard) is only moisture-resistant. PURPLE drywall, manufactured only by Gold Bond Building Products, is superior because it offers moisture, mold and mildew resistance.
Blueboard on the other hand is a type of wallboard that is more absorbent than drywall and specifically designed to bond with a veneer plaster. In New England, drywall is most often used in commercial settings.
PVC has so many advantages compared to drywall or other wall coverings. Vinyl panels have a 100-year shelf life, whereas drywall lasts approximately 30-40 years. Duramax Panels are ASTM-certified, CFIA-certified and FDA-compliant. PVC panels are impact-resistant, whereas drywall is prone to damage.
Hang the Ceiling First
This makes it much easier to manage and attach the panels since you will not have to fumble around with the screws, measuring tape, and so on. Screws for drywall lids should be placed no closer than 16” from the wall. This allows the drywall to have a bit of flexibility to prevent ceiling cracks.
The original product we call drywall today was Gypsum Board. The word gypsum is derived from the original Latin term gypsos, meaning plaster. A form of dry plasterboard was called gypsum.
1/2-inch drywall is the most versatile board and the most common thickness for the 16-inch on-center interior walls in most homes. It offers a good balance between strength and weight. 5/8-inch drywall is a heavier product that resists sagging in ceilings and in 24-inch on-center interior walls.
The minimum wall thickness is 87.5% of the nominal wall thickness. The maximum wall thickness is given in terms of the nominal internal diameter, however. It specifies the smallest diameter and length of a cylindrical drift mandrel that must pass through the casing (see Table 1-2).
