*FIRE SAFETY CAUTION – Passing a fire test in a controlled laboratory setting and/or certifying or labeling a product as having a one-hour, two-hour, or any other fire resistance or protection rating and, therefore, as acceptable for use in certain fire rated assemblies/systems, does not mean that either a particular assembly/system incorporating the product, or any given piece of the product itself, will necessarily provide one-hour fire resistance, two-hour fire resistance, or any other specified fire resistance or protection in an actual fire. In the event of an actual fire, you should immediately take any and all actions necessary for your safety and the safety of others without regard for any fire rating of any product or assembly/system.

Product FAQs

Should gypsum board be installed vertically or horizontally?
Answer

While gypsum boards are stronger in one direction, they may be installed either vertically or horizontally on both wood and steel studs. If the boards are to be used in a fire rated assembly, then use the board orientation that is stated in your specific rated assembly.
