Understanding Drywall

July 26, 2012 · Posted in Family · Comment 

Drywall was invented in 1916 but it took till 1945 to become the dominant constructing material it is today. Before drywall, the inside of homes were finished with plaster and lathe. This demanded a substantial amount of labor and time. With an experienced crew it is possible to drywall an entire home and be ready for priming and painting in just one day. Comprehending the types of Drywall will help you purchase the suitable type for the right job.

Originally drywall came in tiles used for fireproofing but by 1926 it took on the form we know today. Each piece has a plaster core called gypsum that lies between heavy paper sheets. It received its name because it is not wet when applied. Drywall is preferred over plaster and lathe finishes because it takes less effort to apply and does not need time to dry. You measure the dimensions, cut to size if needed, nails or screws to secure it to a wall and then finish the drywall by applying thin coats of plaster over nails and seams.

When contemplating drywall, select a common length whenever possible. Conventional drywall lengths are 4′ wide and 8′, 10′ or 12′ long. Other lengths are available but will be more expensive. The common thickness of these sheets are 1/2” but 1/4”, 3/8” and 5/8 thicknesses are also available. A commercial interior supply company can help you decide what is best for your construction project. Building and construction codes may come into place if a certain fire rating is needed.

Consider the surface you are applying drywall to first. Drywall thickness is typically 1/4” or 3/8” pieces in many instances. When in doubt, 1/2” drywall is the most recommended. The 1/2” thick drywall is designed for walls with studs that are 16” on center. 5/8” drywall is used when the centers are wider than 16”.

Curved walls do not follow the typical rules. They call for a combination of 1/4” and 3/8” drywall applied in layers. It is best to the drywall to make it flex better with a spray bottle of water. Curved walls take more patience, so go slow, and secure your work by nailing or screwing as you progress. Be mindful to avoid breaking the paper surface with your fasteners and double screw or nail the edges. Layer the drywall until it is at least 1/2” thick.

There are two types of drywall. Type X drywall is the most common and has an excellent fire rating. This is a great choice if you are installing drywall between a home and a garage or have multifamily residences with a needed fire rating. Your local building department can point out specifications you should be aware of.

Special rooms require a special type of drywall. Moisture Resistant Drywall or MR is for bathrooms, laundry rooms, shower enclosures or any other room with high moisture content. It is easy to use and is essentially installed the same way as standard drywall.

Being familiar with the types of drywall can be important to a project. Acquiring the right type of drywall can save you time and money.
