Gypsum wallboard is formed by squeezing gypsum amidst two sheets of paper. It is apparently widely used in interior wall facing today. The types of gypsum wallboard can be underscored by the nature of their performance, size and by thickness as discussed herein.
- By performance
Standard drywall is applicable for about 90% of your wallboard applications and has been the solid yardstick for 5 decades and counting. It goes up fast, is fairly easy to operate and finishing it is hassle-free as well. Structurally, it’s not as sound in case of a fire and can slump in humid regions including the bathroom or kitchen.
Water-resistant wallboard, alias the greenboard, is designed for places where it may come into contact with water such as the bathroom or kitchen. It has impermeable substance in the core but allows free flow of air in order for moisture to evaporate through the wall, helping control the growth of mold.
Fire-resistant wallboard isn't resistant to burning per se; it only has a longer burn-through time allowing you sufficient time to whisk your family to safety and for the firefighters to contain the flames. This is why it is a requirement in most codes that it is placed between garages and living spaces.
This fire-resistant wallboard has fiberglass incorporated in the matrix to maintain stability once the heat is on while securing your flammable studs. Option 5/8’’ offers extra protection.
Sound-dampening wallboard is designed with extra inbuilt air spaces to reduce the noise pollution from outside and ensure minimal interference while in the bedrooms.
- By size
The 4’ by 8’ size wallboard is the most widely used because it fits the height of most walls without needing to cut several times.
Gypsum wallboard is suitable for extra tall walls. It is found in sections 9’, 10’ and 12’. You can also place a special order for the 16’ long gypsum wallboard which is better than the standard 8’ because it means fewer seams where you need to tape and mud.
- By thickness
3/8” drywall available in any drywall supplies store, is pliable and as such can be used on walls 16” tall, as well as on bent walls and archways; basically anywhere that flexibility is required. Its flexibility means it can bend from one end to the other and be securely fastened. This is why it is used in endless design ideas.
The 1/2" drywall is the wallboard widely used in the construction of interior walls. It’s perfect on 12" or 16" centers for ceilings, or on 16" or 24" centers on walls. Maintain a reasonable span from one end to the other when using it on ceilings to keep it from drooping under its weight. After all you want an elegantly finished project.
Unlike the standard drywall the 5/8" drywall is slightly rigid making it perfect for ceilings. It’s firm enough to keep it from sagging under it’s weight. This gives you a long-term elegant finish.
By getting the appropriate wallboard for the job from a drywall supplier, you can ensure that your job will go on quickly, easily and with great end results.
