When it comes to drywall finishing, selecting the right type of drywall plays a key role in the overall success of your project. Not all drywall is created equal. Each type of drywall is designed with a unique set of properties that support safety, durability, soundproofing, and moisture control.
Whether you’re tackling a residential remodel or a large commercial build, knowing the different types of drywalls will help ensure a smoother installation and long-lasting finish.
Below, let’s examine the most common drywall types, their features, and ideal applications.
Understanding the Different Types of Drywalls Used for Drywall Finishing
We take a closer look at the different types of drywalls available today and how they support different finishing needs.
1. Regular Drywall (Standard Drywall)
This universal drywall is the go-to choice for most residential and commercial projects. It’s versatile and suitable for almost any drywall finishing application. Regular drywall is commonly available in various thicknesses, with 1/2-inch and 5/8-inch being the standard options. Its ease of installation and cost-effectiveness make it a staple in construction and renovation projects.
2. Moisture-Resistant Drywall
For areas prone to high humidity or moisture exposure, such as bathrooms, kitchens, or basements, moisture-resistant drywall is the ideal choice. Composed of a water-resistant core, this type of drywall helps prevent the growth of mould and mildew. Its green or blue paper backing distinguishes it from regular drywall and ensures added protection against moisture-related issues in the drywall finishing process.
3. Fire-Resistant Drywall (Type X and Type C)
When fire safety is a top priority, fire-resistant drywall comes into play. Type X and Type C drywalls are engineered to withstand fire for an extended period, providing valuable time for occupants to evacuate a building. These types of drywalls are crucial in areas where building codes require enhanced fire resistance, such as in multi-family residences and commercial spaces.
4. Soundproof Drywall
Designed to reduce sound transmission between rooms or living spaces, soundproof drywall, also known as acoustical drywall, is an excellent drywall finishing choice for home theaters, recording studios, media rooms, offices, or shared walls in multi-family buildings where noise control is essential. This type of drywall features additional layers and materials that absorb and dampen sound vibrations, creating a more acoustically controlled environment.
5. Mould-Resistant Drywall
Any environments that are likely to be vulnerable to mould growth, such as damp climates or spaces with poor ventilation, are best fortified with mould-resistant drywall as a great preventive measure for drywall finishing. This type of drywall incorporates additives that resist the development of mould, providing a cleaner and healthier indoor environment. It is particularly beneficial in areas with high humidity levels or where water damage is a concern.
6. Blue Board Drywall
Commonly used in plastering applications, blue board drywall features a special moisture-resistant paper facing that provides a solid base for veneer plastering. Its unique characteristics make it an excellent choice for achieving a smooth and durable finish in applications where traditional drywall may not suffice. Blue board drywall is often used in high-end residential or commercial projects where a superior drywall finish is desired.
7. Paperless Drywall
For those concerned about mold and moisture resistance, paperless drywall offers a perfect drywall finishing solution. This type of drywall replaces traditional paper facings with fibreglass mats, eliminating the organic material that mould needs to thrive. Paperless drywall is a suitable option for areas with high humidity levels or where moisture control is very important.
8. Lightweight Drywall
When weight is a concern, such as in remodeling projects or where load-bearing capacity is limited, lightweight drywall comes into play. This type of drywall is engineered to be lighter than regular drywall without compromising on strength and performance. Its reduced weight makes it easier to handle during installation, making it an ideal choice for various residential and commercial drywall finishing applications.
Types of Drywalls
| Drywall Type | Key Feature | Best Use Case |
| Regular (Standard) | Basic, versatile | General walls/ceilings in dry areas |
| Moisture-Resistant | Resists humidity | Bathrooms, kitchens, basements |
| Fire-Resistant (X, C) | Fire-rated core | Garages, apartment walls, code-compliant builds |
| Soundproof | Reduces sound transmission | Theatres, studios, shared living spaces |
| Mould-Resistant | Inhibits mould growth | Damp areas, poorly ventilated rooms |
| Blue Board | Ideal for veneer plastering | High-end interiors, plaster finishes |
| Paperless | No organic material, mould-proof | Commercial kitchens, hospitals |
Why the Right Drywall Matters
Choosing the right drywall impacts not just the durability and appearance of a space, but also the safety and air quality of the building over time. Specialized drywall types are often required to meet local building codes or architectural standards, especially for moisture resistance, soundproofing, and fire safety.
