Typical Drywall and Insulation Installation. Click on the pictures to view larger images and captions.
Because of the extreme heat in Las Vegas, insulation is an important factor in the construction of the home.
The purpose of the insulation is to provide a continuous thermal barrier to minimize heat flow through the walls, ceiling and floor. Insulation keeps the home comfortable and reduces the costs of heating and cooling.
The home will not be as comfortable and energy costs will be increased if insufficient insulation is installed, or it is installed correctly, such as being compressed or installed with gaps or voids.
Drywall installation involves nailing or screwing the sheets to the studs. Drywall installers cut the sheets to fit, and holes must be cut to accomodate pipes and mechanical equipment. The sheets are then fastened to the studs in a process called hanging. While most drywall installation used to use nails, screws are now the most commom. Drywall is normally installed perpendicular to (across) the ceiling joists and wall studs, and the ceiling is always installed first.
Special moisture resistant drywall is used where excessive moisture may be a problem, such as bathrooms. In most cases, the moisture resistant drywall is green. Fire-rated drywall (Type X) is used where building codes require it. Typically in garages and under stairs.
After the drywall is installed, special metal corner strips ("corner bead") is installed on all corners. This helps to protect the edges of the drywall and provide a nice straight finished edge. Joint compound (drywall mud) is used to finish all joints, nail heads and corners. In most cases, two or three coats of compound are needed at all taped joints. The texture coat is applied last.
