Specialty Drywall Systems
Water-Resistant Drywall
Water resistant drywall systems cover the range of products above standard moisture resistant board, including fiberglass faced panels and cement board. These are specified where the surface will contact water directly rather than only elevated humidity.
About Water-Resistant Drywall
There is a meaningful hierarchy here that gets flattened in everyday conversation. Standard board handles dry rooms. Moisture resistant board handles humid rooms. Fiberglass faced water resistant panels handle wet environments. Cement board plus a waterproofing membrane handles direct water contact behind tile.
Choosing correctly is a matter of asking where liquid water will actually land. A bathroom ceiling gets humidity. A wall next to a shower gets splash. The inside of the shower gets water running down it continuously. Those three conditions call for three different materials, and using one product for all three either wastes money or causes failure.
Why this matters
- Material matched to actual water exposure rather than to the room name
- Fiberglass facing where paper would be a mold food source
- Cement board and membrane where tile meets direct water
- Correct fasteners and sealing for wet environments
How we work
Our Process
How a water-resistant drywall project runs from first contact through final walkthrough.
Step 1: Define the Performance Target
Moisture, fire, sound, and impact are four different problems. We establish which one you are actually solving before specifying anything.
Step 2: Specify the Assembly
Performance comes from the complete assembly, not the board alone. We specify board, framing, insulation, fasteners, and sealing together.
Step 3: Written Scope
The estimate names the specific board type and assembly details, so what you are buying is unambiguous.
Step 4: Build to the Detail
Specialty assemblies only perform when built exactly as listed. We follow the detail rather than approximating it.
Step 5: Verify and Document
Assembly checked before close in, documented where an inspection or rating depends on it, then finished and cleaned.
Scope
What's Included
Written into every estimate so there is no ambiguity about what you are paying for.
- Exposure zone mapping across the space
- Material specification per zone
- Board and backer installation
- Waterproofing membrane coordination where tile follows
- Corrosion resistant fastening
- Joint treatment appropriate to the material
