Gypsum Board

Gypsum Is Fire-Resistant: Gypsum boards are fire resistant and safeguard the structure from fire threats by preventing the fire from spreading further. Due to chemically bound water in the gypsum, it possesses a fire-resistant quality. When gypsum boards are exposed to fire, the water contained within the gypsum evaporates, forming a protective layer.

Thermal Properties of Gypsum: Gypsum can regulate variables such as humidity and temperature in the home. The insulating characteristics of gypsum plasterboard or formwork used in buildings are improved.

Acoustic Property of Gypsum: Sound isolation is prioritized in the design of gypsum materials. Other methods, such as masonry, would work well, as it is commonly used in a thicker thickness and is no less demanding than gypsum. Gypsum plasterboard is designed to absorb sound and reduce reverberation.. Adding an air space between two solid gypsum walls improves acoustic performance by preventing noise from passing through. For example, instead of a 110mm thick brick wall, we can use 75mm thick drywall to obtain the same sound performance.

Non-combustible Property of Gypsum: The heating of gypsum products causes the water crystals in the gypsum material to heat up. Calcinations is the process of dehydrating gypsum with heat. Calcinations creates a protective layer over the components, preventing them from combusting and allowing the materials around them to retain a lower, safer temperature.
The residue will act as an insulating layer until it is separated, even after the water crystals have been entirely calcined. Because of its non-combustible quality and capacity to slow fire development for hours depending on the extent to which gypsum products are utilized, gypsum is regarded as an effective fire retarder.

Chalk line: A tool used for making accurate, straight lines for cutting drywall panels.

Drywall hammer: A special hammer with a wide, beveled head used in the installation of drywall. Also known as a hatchet.

Keyhole saw: A narrow, pointed hand saw used especially for cutting openings in gypsum board for electrical outlets, pipes and ducts. Sometimes called a “drywall saw.”

PPE (Personal Protective Equipment): Safety gear worn to provide protection during drywall installation, which can include a dust mask, gloves, ear plugs and safety glasses.

Rasp: A coarse file to smooth ragged drywall edge cuts.

Screw gun: A power tool used to drive drywall screws through drywall panels into framing with the ability to set the depth of penetration.

T-square: A tool used as a guide to help cut drywall to size. Extended to 48 inches, it’s long enough to aid in making an even, straight cut across the entire width of a sheet of drywall.

Utility knife: A knife with a small sharp blade, often retractable, used for cutting drywall.

Utility Saw: A short handsaw with very coarse teeth for cutting drywall for door and window frame openings.
