These gypsum panels are durable and offer cleanliness on the food processing areas. They are usually vinyl laminated to seal out dirt, moisture and odors. The vinyl surfaces are embossed and therefore are exceptionally stain resistant. They can also withstand repeated washings. Lighting efficiency is maximized since they have exceedingly reflective surfaces.

Using the laminated vinyl finish, there is no more dependence on additional finishing.

Don’t use anything but an approved suspended system for exterior use when being installed outdoors.

The gypsum boards appear in 1/2″ and 5/8″ thick type X fire rated. A type X fire rating implies that the board has a minimum fire rating of a single hour, the requirement of most building codes. It’s more fire resistant plus more expensive than the standard boards. Fire rated boards are generally required in living room areas and in such areas that are susceptible to fires.
