q & a
-
What is the maximum spacing allowed between gypsum panels over framing?
The maximum space allowed between panels is 1/8 of an inch. Any space larger can lead to problems with joint finishing cracking.

Can gypsum panels be installed horizontally?
Gypsum panels can be installed horizontally or vertically. Installing the board horizontally lessens the total amounts of joints to be taped by 25%.
-
Can I store Sheetrock® Brand Gypsum Panels outside?
Sheetrock® Brand Gypsum Panels must be protected from exposure to excessive or continuous moisture and the elements before, during and after installation. Storing outdoors uncovered is not recommended.
