Different Types of Gypsum Board Used in Construction and How to Identify Them Visually

Introduction

Gypsum board, also known as drywall, is a popular building material used in construction for walls, ceilings, and partitions. It is made from a core of gypsum, a naturally occurring mineral that is fire-resistant and non-combustible. Gypsum board comes in various types based on its properties, which are designed to meet specific building requirements. In this article, we will discuss the different types of gypsum boards and how to identify them visually.

1. Regular Gypsum Board

Regular gypsum board is the most common type of gypsum board used in construction. It is a standard gypsum board that is suitable for most applications. The core of the regular gypsum board is made of gypsum plaster, which is sandwiched between two sheets of paper. The paper provides a smooth surface for painting or wallpapering. Regular gypsum board can be identified visually by its white paper covering.


2. Moisture-Resistant Gypsum Board

Moisture-resistant gypsum board is designed for use in areas with high humidity or moisture, such as bathrooms, kitchens, and laundry rooms. The core of the moisture-resistant gypsum board is treated with a moisture-resistant additive that makes it more resistant to water damage than regular gypsum board. Moisture-resistant gypsum board can be identified visually by its green paper covering.

3. Fire-Resistant Gypsum Board

A fire-resistant gypsum board is designed to provide additional fire protection to buildings. It is made by adding glass fibers to the core of the gypsum board, which increases its resistance to fire. Fire-resistant gypsum board is classified into two categories – Type X and Type C. Type X gypsum board is more fire-resistant than Type C gypsum board. Fire-resistant gypsum board can be identified visually by its pink paper covering.


4. Soundproof Gypsum Board

Soundproof gypsum board is designed to reduce noise transmission between rooms or buildings. It is made by adding a layer of sound-dampening material to the core of the gypsum board. Soundproof gypsum board is commonly used in music studios, theaters, and other spaces where sound quality is important. Soundproof gypsum board can be identified visually by its purple paper covering.



5. Impact-Resistant Gypsum Board

Impact-resistant gypsum board is designed for use in areas where the walls may be subject to impact or abuse, such as hallways, stairwells, and schools. It is made by adding a layer of fiberglass to the core of the gypsum board, which increases its resistance to impact. Impact-resistant gypsum board can be identified visually by its blue paper covering.


6. Mold-Resistant Gypsum Board

Mold-resistant gypsum board is designed to prevent the growth of mold and mildew on the surface of the board. It is made by adding a special coating to the paper that covers the core of the gypsum board. Mold-resistant gypsum board is commonly used in areas with high humidity or moisture, such as basements, bathrooms, and kitchens. Mold-resistant gypsum board can be identified visually by its purple paper covering with a green stripe.


Size

Gypsum board thicknesses range from 6mm (1/4 inch) to 15mm (5/8 inch). The most common thicknesses are 9mm (3/8 inch) and 12mm (1/2 inch). The size of the gypsum board can range from 6 feet by 4 feet to 12 feet by 4 feet. Other sizes are also available, such as 8 feet by 4 feet and 10 feet by 4 feet. It is important to check with the manufacturer or supplier for specific sizes and thicknesses available in the Indian market.

Conclusion

gypsum board is a versatile building material that can be used in a variety of applications. There are different types of gypsum boards available based on their properties, which are designed to meet specific building requirements. By choosing the right type of gypsum board for your project and identifying it visually, you can ensure that your building is safe, durable, and meets all necessary building codes and regulations.
