Heavy drywall, also known as heavyweight drywall or heavy sheetrock, is a type of drywall designed for use in applications where increased strength and durability are required. Unlike standard drywall, which typically has a thickness of 1/2 inch (12.7 mm), heavy drywall can range from 1/2 inch to 5/8 inch (15.9 mm) in thickness. This increased thickness provides enhanced structural integrity, making it suitable for applications such as load-bearing walls, fire-rated assemblies, and areas subject to heavy impact or vibration.

Heavy drywall is composed of gypsum core sandwiched between two layers of paper. The gypsum core is denser and more compact than that found in standard drywall, contributing to its increased strength and durability. The paper layers are typically coated with a fire-resistant material, such as gypsum or vermiculite, to enhance the fire resistance of the drywall.

Heavy drywall is available in various sizes and configurations, including standard 4' x 8' sheets and specialty sizes for specific applications. It can be installed using standard drywall installation techniques, but it may require additional support or reinforcement in certain situations to ensure proper structural integrity.

Heavy drywall is commonly used in commercial and industrial settings, as well as in residential construction where increased strength and durability are required. It is an essential component in the construction of fire-rated assemblies, such as fire walls and fire partitions, which are designed to contain and delay the spread of fire within a building. Heavy drywall is also used in areas subject to heavy impact or vibration, such as gymnasiums, warehouses, and manufacturing facilities, to provide enhanced protection and durability.
