5/8 inch drywall provides better fire protection than 12 mm drywall. Its thicker core slows heat transfer during a fire. This thickness meets many fire-rating standards for residential and commercial buildings. The 5/8 inch type often contains glass fibers or additives to improve fire resistance. In contrast, 12 mm drywall offers basic fire resistance but may not meet stricter fire codes. It suits areas with lower fire risk or where fire-rated assemblies are not mandatory.
Applications For Ceilings And Garages
5/8 inch drywall is ideal for ceilings and garages. These areas require higher fire resistance due to potential fire hazards. Building codes often mandate 5/8 inch drywall in garages to protect living spaces above. It also prevents fire from quickly moving through ceiling assemblies. The 12 mm drywall fits well in interior walls and ceilings without fire-rating demands. It works fine in rooms with minimal fire exposure and where weight reduction is desired.
Durability And Impact Resistance
Durability and impact resistance are crucial factors in choosing drywall. These qualities ensure walls remain strong and intact over time. Both 12 and 5/8 drywall types offer different levels of toughness. Understanding their differences helps select the best option for your needs.
Resistance To Dents And Damage
12 drywall is thicker, offering better resistance to dents. It can handle bumps and knocks without showing damage easily. Thicker drywall reduces the chance of holes from accidental impacts. On the other hand, 5/8 drywall is thinner and less resistant to dents. It may require more repairs in busy environments.
Longevity In High-traffic Areas
High-traffic areas demand drywall that lasts longer under stress. The 12 drywall’s extra thickness adds strength and durability. It stands up better to repeated contact and wear. This makes it ideal for hallways, schools, or commercial spaces. In contrast, 5/8 drywall may wear out faster in these places. Choosing the right drywall improves wall life and reduces maintenance costs.
