⅝ - inch thick drywall
⅝ – inch are more reliable for ceilings as they do not sag as much between the joints than a ½ – inch drywall panel. ⅝ – inch drywall panels are also great for holding textures since it does not sag compared to lighter drywall panels.
It depends on how far apart the studs are. If they are 16 inches a part you can use 1/2 inch sheet rock. If the studs are 24 inches apart you should use 5/8's inch sheet rock.
Drywall compound shrinks as it dries, so if applied thick or if it has too much water it will crack. A few cracks on the first coat are ok since later coats will fill the cracks.
Unfortunately, drywall mud can sometimes crack, which can be a pain to cover.
Premixed joint compounds come in a variety of consistencies, depending on the brand, the factory where they were produced, and even regional formulas. The joint compound manufacturers allow users to add water to the compounds, but the formulas are designed be thinned with water only.
A Level 5 drywall finish involves an additional skim coat of joint compound over the entire surface, providing the highest-quality finish. This level is essential for areas with critical lighting conditions, where the appearance of the wall is paramount. It can deliver a smooth, uniform surface.
Regular drywall, only thick sheets or double-layers: While it does not bring the most soundproofing, it is possible to use sheets of typical building drywall to create better sound resistance. This can either be a thicker piece (such as 5/8” instead of 1/2”) or a double layer of drywall, such as two 5/8” sheets.
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.
Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it slow down the fire. Also, because it is denser than normal gypsum and paper drywall, it takes longer for the fire to degrade it.
Of all the different types of drywall, 4-foot by 8-foot drywall that measures one half-inch thick is the most common option. Other drywall thicknesses, sizes and specialty boards may be available by special order. Get everything you need to finish your drywall project.
Thick walls do us good. First of all, insulation is its number one asset, with thick walls it is easier to keep warm in winter and cool in summer. In addition to keeping a pleasant temperature throughout the seasons, thick walls also help to soundproof your home against noisy neighbours.
Moisture-and-mold resistant drywall is best used for interior walls, especially in areas like kitchens, bathrooms or basements. The best drywall boards for these areas have moisture-resistant cores that prevent water and moisture intrusion from seeping into the board itself.
Drywall type – Most garages use 1/2" standard or 5/8" fire-resistant drywall, depending on local building codes. Moisture-resistant drywall helps to prevent mold in areas with high humidity. Finish level – A Level 2 finish is most common in garages.
In townhouses, for example, the shared walls between units may require double layers of 1/2-inch wallboard to create a very fire-resistant and sound-resistant wall. In ordinary residential construction, doubling up drywall thickness can reduce sound transmission and make for sturdier walls.
Furthermore, double drywall contributes to better fire protection, especially when using fire-rated drywall. It also aids in insulation, making it ideal for homes located in extreme climates.
R-values for Drywall — How Do They Compare? Drywall has a relatively low R-value — about 0.45 at ½” thickness. This is similar to building materials such as siding, concrete, dirt, face brick, particleboard, wood and single-pane glass.
To attain a Level 5 finish, two to three coats of joint compound are applied and meticulously sanded multiple times. This level is the choice for high-end residential or commercial spaces prioritizing a clean and professional appearance.
Level 4 A standard 3 coat tape job for painted surfaces that are not to be coated with gloss, semi-loss or enamel or where shinny wall covering will not be used. Level 5 is a level 4 tape job with one thin coat of compound spread over the surface to minimize texture and even out the surface for shinier finishes.
Level 5. Level 5 drywall finish consists of two coats of joint compound on tape, a fine coat over the walls, and three coats on screw fittings. This costs between $1.75 and $3.50 per square foot.
When joint compound dries, it has to be able to do two things: evaporate and be absorbed. The tiny bubbles, called “pocks,” are trapped air bubbles created because there is a barrier—such as paint or primer or a harder mud, plaster, etc. —that will not let it be absorbed [into the drywall].
