Make sure all little holes to the outside are filled with insulation or caulk. Make sure there is backing Material to attach drywall boon both Sides of all inside (concave) and outside (convex) corners. Insist on or perform the beat installation methods.
Drywall is no place to get cheap. All drywall should be installed perpendicular to framing on both ceilings and walls. Start on the ceilings. Use only coarse-threaded drywall screws.
Countersink all screws and nails, but don't break the surface of the drywall. Bulk drywall is cheap. Don't patch together pieces to save money. You want as few, factory-edged joints to finish as possible. Use drywall or construction adhesive wherever there isn't a vapor barrier, such as inside walls. In bath or kitchen areas use cementious wallboard, such as USG's Durock. wherever ceramic tile will be installed. Regular drywall offers a good level of lire protection.
To increase fire protection near stoves, furnaces and water heaters, a double layer of 'A' drywall will more than double the protection. For maximum protection cemenlious board, such as USGS Durock, is virtually fireproof.

Mark all spots with a pencil. (Pens can bleed through later.)
