One advantage of using drywall or sheetrock is that it only takes a day or two to do unlike the week-long process of the lath and plaster method. Utilizing special construction methods, such as building thicker walls with drywall, offers some sound control.
Additionally, due to the
water
of crystallization in gypsum, drywall offers some fire resistance. Drywall and sheetrock can be damaged from water exposure, resulting in unsightly wicking and even softening of the plaster. Likewise, the paper used in both supports the growth of mold. Lastly, in construction, workers waste up to 17 percent of the material in cutting the panels to size.
Drywall tape seals joints in drywall sheets. It’s made of either paper , which is nonadhesive and requires joint compound, or mesh , which has a tacky backing and doesn’t require joint compound. Although drywall is more common, there are many benefits to having traditional plaster walls, plaster ceilings and plaster moulding. Plaster of paris creates an exceptionally hard surface, which offers great durability. It’s also fire-resistant and not as likely to succumb to water damage . When in its wet state, plaster is a very moldable material and can be used to create beautiful architectural detailing, especially in older homes or newer ones with a vintage theme.
Yes! drywall is quite resilient, although it can be compromised by prolonged contact with water. It could become flimsy and unstable if its structural strength is compromised. Drywall may be salvageable, depending on the type of water it was exposed to and the extent of the water damage. However, time is of the essence in preventing mold damage.
Drywall (gypsum board) is used in north american construction as a faster alternative to plaster and wood. Drywall is made of gypsum (calcium sulfate dihydrate), paper, and additives such as mica, clay, and resin. Drywall installation generates gypsum and silica dust, which are irritating to the lungs. Workers should wear personal protective equipment such as safety glasses, gloves, and dust masks when handling drywall. Drywall that has been damaged by water loses its strength and can grow mold. After very active hurricane seasons in 2004 and 2005, there was a shortage of us-made drywall due to new home construction and rebuilding.

Devices also end sealing uncertainty caused by the special inspections required for high-rise buildings and risk categories iii and iv structures ( chapter 17, section 1705. 16 of the 2012 ibc requires all firestopping to be inspected in accordance with astm e 2174 and e 2393) “there’s no need for destructive testing. A visual inspection confirms fail-safe installation of a metered dosage device,” reports kernan. Architects looking to speed project completion and minimize liability risk should consider writing performance specs that conform to next generation firestopping drywall accessories.

Type X drywall [ edit ]
If you are tackling a drywall job alone, consider ultra-lightweight gypsum board, which is easier to lift, carry and install. Placing drywall in a space where moisture is present, such as in bathrooms, kitchens or homes in humid climates? consider using mold and moisture resistant drywall. We also carry fire resistant drywall for extra protection and peace of mind. Making sure you pick the right drywall size drywall is made in different sizes and width, so you want to be sure to choose the right one. Drywall price depends on the type you are using. While the most common size of drywall is 4 x 8 foot x ½ inch , we also carry 4 x 10 and 4 x 12 drywall.
Hisham ibrahim / getty images drywall mud, also called joint compound, is a gypsum-based paste used to finish drywall joints and corners in new drywall installations. It's also handy for repairing cracks and holes in existing drywall and plaster surfaces. Drywall mud comes in a few basic types, and each has its advantages and disadvantages. You may choose one type for your project or use a combination of compounds for the desired results.
When it comes to choosing the right type of drywall for your home, consider its use and the room it will be installed in. For example, most living rooms and bedrooms are suitable for regular drywall, but bathrooms and kitchens should have moisture-resistant options like green board. Purple drywall may be necessary in bathrooms that see considerable amounts of water around the shower walls. Additionally, most building codes require type x drywall to be used in garages and walls that separate two living spaces (such as shared walls in apartments, condos, and townhouses). This is an important step to help slow the spread of potential fires.
Drywall continues to improve. Today you can purchase sheets of drywall in almost any size needed. In addition to the variety in lengths and widths available there are different types of gypsum board for different applications. Fire retardant drywall panels are used in nearly every type of construction. There are drywall panels that can hold up in increased moisture conditions. There is drywall that resists mold growth. There is drywall that resists indentation for use in high traffic or high abuse areas. There is drywall specifically designed for elevator shaft application where fire protection is extremely critical.
