Fire-Rated Board • Family-Owned Since 1970 • CSLB #265709
Type X Drywall — and What “Beyond” Actually Means
Type X is fire-resistant gypsum, usually 5/8-inch, used in listed wall and ceiling assemblies. The rating is the whole wall — studs, layers, joints — not a single sheet.
We Hang the Specified Assembly
Ron Hogan Drywall has been family-owned since 1970. We hang Type X on wood and metal studs for garages, corridors, and commercial interiors in the Bay Area and Northern California. If your drawings call out a 1-hour or 2-hour wall, we follow that listing — we do not invent one on this page.
What Type X Is
Type X gypsum has glass fibers and additives so the core holds together longer in a fire test than regular board. The common panel is 5/8-inch. 5/8-inch is not automatically Type X. Look at the stamp.
Regular 1/2-inch board is fine for many living rooms. It is the wrong product when the plan or the code wants a rated assembly. All board types →
Where Type X Shows Up
Garages
The wall between a garage and living space is a common rated-wall job.
Multi-family and commercial
Corridors, tenant separations, and listed partitions. Commercial drywall →
Ceilings in rated assemblies
When the listing calls for Type X on the ceiling, that is the panel — not leftover wall board.
“1-Hour” Is the Wall, Not the Sheet
Tested assemblies (often under ASTM E119 / UL listings) can reach 1 hour, 2 hours, or more with the right layers, joints, and studs. A single piece of Type X leaning in a garage does not give you that number.
If the inspector wants a listed wall, bring the listing. We will hang to it.
Beyond Type X
- Type C or other listed panels when the assembly names them
- Multiple layers where the listing requires them
- Metal studs on many commercial rated walls
- QuietRock when sound is the spec — that is not a fire shortcut
Fire, sound, and moisture are different products. Do not swap them.

Type X FAQs
Is Type X much more expensive?
The panel usually costs more than regular 1/2-inch — often in the neighborhood of 20–30% on the board itself. Labor follows the assembly, not that percentage.
Can I use leftover 1/2-inch on a garage wall?
Not if the wall is required to be rated. Use the specified Type X (or listed) panel.
Do you inspect for fire code?
The building inspector signs the rating. We install what the drawings and listing require.
Need Type X on a Rated Wall?
Send the spec. The family-owned Bay Area crew since 1970 will hang the assembly on the drawings.
