Drywall, also commonly referred to as sheetrock or wall board, is a lightweight cost efficient product for use on interior walls or ceiling panels in new construction, renovation and repair work. In residential construction the most commonly used sizes are 4′ x 8′ x ½. Other sizes, thicknesses and specialty boards may be stocked and/or available by special order. Drywall can be nailed or screwed to wood or metal studs. When used on ceilings it’s also sometimes glued up to help keep it from sagging over time. The 5/8” thick panels offer additional fire resistance where certain fire-ratings are required, and because of their extra thickness can also offer increased room to room sound control. Moisture resistant drywall is typically used in areas prone to moisture, such as bathrooms, laundry rooms, basements, garages, kitchens and utility rooms.
