Mold Resistance: Magnesium wall board stops mold and fungi. This helps keep your home safe and healthy.
Longevity: Magnesium wall board costs more at first, but it lasts longer and needs fewer repairs. Drywall is cheaper but may need fixing sooner.
Here is another quick chart to help you remember the benefits:
Magnesium wall board is best for fire, water, and mold resistance.
It works well in places with moisture or fire risks, like bathrooms or kitchens.

Traditional Drywall Performance
Traditional drywall gives some fire protection, but not as much. Regular drywall lasts up to one hour in a fire. Type-X drywall lasts up to two hours. Type-C drywall lasts up to four hours. Here is a simple table to show the difference:
Drywall Type | Fire Resistance |
|---|---|
Regular Drywall | Up to 1 hour |
Type-X Drywall | Up to 2 hours |
Type-C Drywall | Up to 4 hours |
Most homes use regular drywall. It does not protect as well as magnesium oxide wallboard. Drywall can lose strength if it gets wet or damaged. You may need to replace drywall after a fire, even if flames did not touch it. This makes your walls less durable.
