This is not recommended for do-it-yourselfers because, unless you are experienced with drywall, there is a high likelihood that you may need to readjust a sheet or even reinstall it. Slightly angle screws on the ends of sheets, where there is only 3/4-inch of wood left to catch screws. If desired, you can install foam insulation panels against the ceiling surface (see steps 2 to 7 above). Plasterboard 120 centimetres (47in) wide is most commonly made in 240 centimetres (94in) lengths; sheets of 250,260,270,280, and 300 centimetres (98,102,106,110, and 118in) and longer also are common.

EcoRock, a drywall that uses a combination of 20 materials including recycled fly ash, slag, kiln dust and fillers and no starch cellulose; it is advertised as being environmentally friendly due to the use of recycled materials and an energy efficient process. For rooms with walls of odd shapes, you can refer to math calculators to determine their surface areas. Sound transmission may be slightly reduced using regular 5⁄ 8-inch (16mm) panels (with or without light-gauge resilient metal channels and/or insulation), but it is more effective to use two layers of drywall, sometimes in combination with other factors, or specially designed, sound-resistant drywall. Gypsum will soften with exposure to moisture and eventually turn into a gooey paste with prolonged immersion, such as during a flood.Drywall is one of the cheapest building materials on the market, which makes it an easy and convenient option for beginner DIY projects. If you live in an area large enough to support a commercial supplier, it’ll offer more variety than an average lumberyard.

Although we don’t show one in use here, pros now use a spiral saw to cut openings for outlets, lights and even doors and windows. Organic dispersants and plasticizers are used so that the slurry will flow during manufacture and to reduce the water and hence the drying time.This board is similar in composition to Type X, except for more glass fibres and a form of the vermiculite used to reduce shrinkage. Next, you’ll need to know the weight per square foot, which looking at a 1/2″ standard drywall sheet for this example, is 2. Check the furring strips in both directions with a carpenter's level to make sure they are flat and level.

Gypsum board evolved between 1910 and 1930, beginning with wrapped board edges and the elimination of the two inner layers of felt paper in favor of paper-based facings. Also important are the construction details of the framing with steel studs, wider stud spacing, double studding, insulation, and other details reducing sound transmission.For obstacles such as ceiling electrical boxes, use a wallboard saw or utility knife to cut openings or notches to fit the insulation panel. citation needed] Sackett Board was invented in 1894 by Augustine Sackett and Fred Kane, graduates of Rensselaer Polytechnic Institute.
