DRYWALL (Gypsum Board, Plasterboard)

Drywall is a sheet material having a gypsum core faced with paper on each side, used for covering walls or as lath.

Gypsum board is the name for a family of panel products consisting of a non-combustible core, primarily of gypsum, with a paper surfacing on the face, back and long edges.

Gypsum is one of the oldest building materials known to man. The ancient Egyptians used a form of gypsum in the construction of the pyramids. The Greeks, who called the substance "Gypsos," fashioned their temple windows from gypsum so that light filtering through appeared similar to moonlight.

    Types

    Regular

    Regular Gypsum Wallboard
    with tapered edge permits smooth joint treatment; surface takes any decoration. Basic recommendations: 1/2" board for single layer; 3/8" board for 2-layer; 1/4" board is regular gypsum wallboard used in remodeling and sound control in double layer applications.

    Regular Stretch Gypsum Wallboard

    Regular Foil-Back Gypsum Wallboard
    a wall board panel consists of a fire-resistive gypsum core encased in heavy natural-side and strong liner paper on the backside to which aluminum foil is laminated. The ends are square cut and finished smooth.

    Regular Water-Resistant Gypsum Wallboard (MR Board) called as Green Board
    a wall board specially processed for use as a base for ceramic and other non-absorbent wall tiles in bath and shower areas. Facing paper is colored light green.

      

    Fire Rating - 45min., 1HR, 2HR, 3HR, 4HR

    The term Fire Resistance designates the ability of a constructed assembly to contain a fire. Such an assembly might be a partition, a floor/ceiling or a protected column. The degree to which such assemblies prevent the spread of fire or damaging heat is indicated in intervals of time. If a construction assembly contains the fire and heat for two hours and meets other requirements during the test, it is given a two hour Fire Resistance rating.

    Cost

    Drywall comes in size 4X8. Cost will be calculated by linear size of the area and ceiling height; wall types affect the cost.

     

    Primer

    Primer is a paint material specifically formulated to fill the pores and equalize the suction difference between gypsum board surface paper and the compound used on finished joints, angles, fastener heads and accessories over skim coatings.
