It is true what we said in drywall history that fireproof is one of its intrinsic properties. But since every building (or room) has a different kind of use, it's also true that materials and construction methods using for each kind of building should be different than the others. Drywall is one of the most common materials using in building constructions, Therefore there should be different types of drywall.
Well there is.
Drywall or other names people use like wallboard or plasterboard is a board installed on walls to cover it up and give a nice simple interior view to buildings. But it's not just about nice views, cause there is lots of properties. For most important example, it is fireproof by natural. And in compare to the other materials like plaster, it costs less, even its repairs cost less. No surprise that it's the most common construction material used in USA.
Drywall panel consists of two paper sheets that sandwiched gypsum. That's why it's fireproof, cause gypsum has fire resistance by natural. But on the other hand it can't show much resistance against moisture. But drywall (like any other thing) had improvements overtime. It's been around for more than a hundred years and since 1888 that there was a plasterboard in Rochester Kent, United Kingdom it had a lot of upgrades.
Drywall is the best choice in constructions. That's because in spite of its low costs, it has a lot of benefits and above all, it has very easy installation. Nowadays there is a lot of drywall types that people can use in their constructions. But the important issue is that you should know these categories so you can choose the right drywall for your new building.
All types of drywall
Drywall has lots of types. Some categorized by color and some by letters. Keep an eye on each one and its unique properties so that you can choose wisely. Pick the best to answer your building's need. Let's start with the basic one.
1. Traditional drywall
Regular drywall or White board: Regular drywall or white board is the most common type used by many people. It is the basic drywall without any enchantment. Make no mistake though, cause it isn't inferior or something. It performs as equal as other types in its basic use, just has no extras. For example (and as I said in the previous article) we know that gypsum is naturally fire resistant and as a result the drywall panel becomes fire retardant. But in compare to type X or C (fireproof types) it isn't enchanted by any special fire resistant material.
You can find white boards in 1 to 3.8 inch thick. It is between 8 to 16 feet length (by your choice) and width is usually 48 inches. white board has two type of edges. The square edge which is best when you use plaster finish. And the tampered edge which is best when using drywall tape and joint compound for finishing.
2. Moisture resistant
Water damage is a common thing in buildings and houses specially in kitchens and bathrooms. So ti's better to use moisture resistance type in places like these. Moisture resistance drywall has a special layer to minimize water damage. There are some color categories you can read below:
Green board: As its name implies this type has green covering. Its used often in kitchens and bathrooms or laundry room walls. Green cover has a water resistant. Although it's a little bit more expensive than the regular one, it doesn't mean that it has fully resistance against moisture. It simply can't get in contact with water and survive, cause It isn't waterproof. But in its price, offers a nice resistance to moisture.
Blue board: Blue board is another water resistant type that specialized for veneer plaster using. Water and mold resistance in this type is a more than green one and has qualities like unique absorption. Like the green one, it's often used in high moisture places like bathrooms. But blue board has an advantage in compare to green which makes it more popular. It is slightly soundproof.
Purple board: If you have a room or place which definitely water contact will occur then you should choose purple drywall. purple type performs like regular type plus high water resistance that can contact with water and survive. This type stops growth of mold and mildew which are insidious and cause health problems and grow fast in high humidity palaces. Purple drywall often refers as mold resistant drywall.
Paperless board: This category is a little bit different. It has the same gypsum core but instead of paper layers, contains of two fiberglass cover on each side. As is clear, paperless type also has high water resistance and can stand against moisture and mold. It used for high humidity places. But although it has high resistance, it shouldn't get in contact with water.
Cement board: Cement board is also another choice for high humidity places like baths and showers. It can survive from water. It makes of reinforcement cement which has fibers that makes it very though. It's a very good base for ceramic tiles used in high humidity places.
Always remember that in high moisture places don't confine yourself with moisture resistant drywall and go for more protections like cement board that we told you about.
3. Fire resistant
Fire resistant drywall is a necessary and important type in constructions and buildings due to the building codes in some countries including USA. There are two type of fire resistant drywall: X and C. Although all types of drywall are fire resistant by natural, this two types have extra resistance against fire and can hold on a couple of hours so in emergency moments like when building get on fire, the residents have time to evacuate. This types are thicker than the others and have special layers of non-combustible fibers to provide fire resistance.
Type X: X Is the little brother of C. Also known as fireproof drywall or X board. It is the same gypsum core which is reinforced with special non-combustible fibers that we told you about. It has 5.8 inches of thickness and can hold on to one hour in fire.
Type C: Obviously the bigger brother has more to offer. Type C drywall can hold on more under fire pressure and thus provides 2 to 4 hours time in emergency times. It has between 1.2 to 5.8 inches thick and contains of even more glass fibers. The gypsum in its core has shrinkage-compensating vermiculite.
4. Soundproof drywall
For those who like a quiet place this type is the best. In comparison to other types of drywall, soundproof type functions as well but it optimized to reduce sound passing and get vibrations. It has laminated layers like wood fibers or plastic polymers, ceramic, metal and glue. As it clear it's more dense and stiff so it reduce sound vibrations. Soundproof drywall is used often for family rooms, music studios.
5. Eco-friendly drywall
Eco-friendly or environmentally friendly drywall is a good choice for everyone. It's been around a while that this board are developing. In the field of quality, they are nothing less than the other types of drywall. But even better, cause they're earth-friendly and protect environment.
There is two types in market:
Enviroboard: Which consist of environmentally friendly materials like waste fibers of agriculture and newspapers. They are compressed til the hole compound become like concrete and then they make panels out of it.
EcoRock: Which composed of different recycled industrial byproducts like slag and kiln dust. These mixed byproducts composed with water and some fillers to create drywall panels. Also it has properties like resistance to mold and termites.
It is wise to know what is your building's user and then choose from these different types of drywall. But always remember that the most important thing is to see the big picture. So we recommend for you to use Eco-friendly panels to protect mother earth.
Till next time.
