Drywall Types Explained: Standard, Mold-Resistant, Fire-Resistant

Not all drywall is created equal. Whether you're doing a basement finish, building out a commercial space, or working on a kitchen remodel, knowing which type of drywall to use can save you time, money — and potential repairs down the road.

Here’s a breakdown of the three most common drywall types, what they’re used for, and how to tell them apart.

1. Standard Drywall (White Board)

✅ What it is:

The most basic and widely used type of drywall. It’s made of a gypsum core and standard paper facing on both sides. It’s usually white or gray in color.

🔧 Best for:

• Bedrooms
  
  
• Living rooms
  
  
• Offices
  
  
• Anywhere that stays dry
  
  

💡 Things to know:

Standard drywall is not moisture-resistant, so avoid using it in bathrooms, laundry rooms, or basements unless you’re pairing it with proper waterproofing.

2. Mold-Resistant Drywall (Green or Purple Board)

✅ What it is:

Also known as “green board” or “purple board,” this drywall is treated to resist moisture and mold growth. It has a fiberglass mat or treated paper facing instead of standard paper.

🔧 Best for:

• Bathrooms
  
  
• Laundry rooms
  
  
• Basements
  
  
• Utility rooms
  
  

💡 Things to know:

Mold-resistant drywall is more expensive than standard drywall, but worth it in high-humidity or damp environments. Not waterproof — just water-resistant.

3. Fire-Resistant Drywall (Type X)

✅ What it is:

Fire-rated drywall, often labeled as "Type X," contains fiberglass strands and other additives that help it resist burning and slow the spread of fire.

🔧 Best for:

• Garages (especially walls adjacent to living space)
  
  
• Furnace rooms
  
  
• Shared walls in multi-family housing
  
  
• Commercial buildings
  
  

💡 Things to know:

Fire-resistant drywall is typically 5/8” thick (vs. 1/2” for standard) and heavier. You might be required by local building code to use Type X in certain areas.

Bonus: Other Specialty Drywall Types

• Soundproof Drywall: For recording studios, bedrooms near mechanical rooms, or apartments.
  
  
• Moisture- and Fire-Resistant Combo: Available for areas like commercial kitchens or bathrooms in multifamily builds.
  
  
• Ultra-Light Drywall: Easier to lift and install; used when time or labor is tight.
  
  

Final Word: Match the Drywall to the Room

If you’re a builder, contractor, or DIYer, make sure you’re choosing the right type of drywall for the space. Using the wrong board can lead to mold issues, failed inspections, or even fire code violations.
