Drywall construction: Types, Uses

A versatile building material called drywall is used to build or cover walls and ceilings. It comes in a wide range of materials and constructions, including mold-resistant, plasterboard, and VOC-absorbing. Drywall, one of the most often used and well-liked building materials, is a crucial component of every home renovation and refinishing. Drywall is inexpensive and, more significantly, highly water and fire-resistant, making it an anodyne material for home walls.

What is Drywall?

Drywall is a type of construction material that is used to cover the framing on walls and ceilings. It is made of gypsum, a naturally occurring mineral that is abundant. Raw gypsum, plasticizer, finely crushed gypsum crystal, foaming agent, ethylenediaminetetraacetic acid (EDTA), wax emulsion, and different additives are used to make gypsum plaster. To make rigid boards or panels, the mixture is sandwiched between the outer sheets and cured. Plasterboard, gypsum board, and sheetrock are further names for drywall.

And when it comes to drywall installation, it is used to be installed on the interior sides of walls and ceilings. To give the quick-set gypsum (plaster) stress and lessen flammability, mildew, and water absorption, it is blended with paper fiber, fiberglass, a blend of these two materials, foaming agent, plasticizer, or other materials.

Types of Drywall

There are various drywall types, which are typically distinguished by the color of the paper that surrounds the drywall. Some of the common types of drywall are listed below. Let’s find out;

  • Regular drywall

The most popular type of drywall used for walls and ceilings in residential and commercial construction is regular drywall, sometimes known as the whiteboard.

  • Mold-resistant drywall

The paper backing of mold-resistant drywall, sometimes known as “green board,” is thicker than that of ordinary drywall, and it is wax-coated for added moisture resistance. Mold-resistant drywall is frequently used in bathrooms, kitchens, and laundry rooms, as well as as a tile backer.

  • Plasterboard

Plasterboard, also known as the blue board, is used as a substrate for plaster applications, similar to lath in lath and plaster walls. It’s commonly used in older homes to simulate lath and plaster.

  • Soundproof drywall

All drywall has some soundproofing properties, but soundproof drywall contains more wood fiber, gypsum, and polymers added to it than conventional drywall does. When more soundproofing is needed, such as between living areas and common walls, soundproof drywall is used.

  • Fire-resistant drywall

Around potentially flammable equipment in garages and basements, specialized fire-resistant drywall is used. It contains fiberglass, which retards the spread of fire and burns more slowly than standard gypsum. Type X and Type C are the two varieties of fire-resistant drywall available. Type X offers up to an hour of fire protection and can be utilized in numerous layers for more security if necessary. Similar to Type X, Type C does not shrink when burned.

  • VOC-absorbing drywall

VOC-absorbing drywall absorbs chemicals and other volatile organic compounds and retains them within the drywall, making them inactive. These chemicals are found in both the cleaning supplies we use on a daily basis and other building materials.

Drywall Screws

The most common fastener for attaching whole or partial sheets of drywall to wall studs or ceiling joists is a drywall screw. Drywall screws come in two varieties: coarse thread and fine thread.

  • Coarse-thread drywall screws, often known as W-type screws, are best for most drywall and wood stud applications.
  • Fine-thread drywall screws, commonly known as S-type screws, are self-threading and therefore suitable for use with metal studs. The best drywall screws for attaching drywall to metal studs are fine-thread drywall screws because of their pointed tips.

Terrace Screws

Terrace Screws are also used to install decking on wooden substructures because they provide extra strength for the hardwood industry.


When it comes to interior design, drywall is also growing in popularity. It can make shelves, arch openings, room partitions, and coffers in the ceiling. As well as fake ceilings and a variety of other appealing features that can improve a home’s aesthetic appeal.
