Gypsum board is considered an ideal choice in modern decor, but choosing the wrong type can lead to costly structural problems. In this article, we will review the fundamental differences between the most common types and how to choose the most suitable for your home.
What is White (Regular) Gypsum Board and the Best Places for its Installation?
White gypsum board is the most common type used in simple interior decoration works. It consists of a gypsum layer covered with treated white or light gray cardboard. This type is characterized by its light weight and economical price, making it the first choice for projects with limited budgets.
White gypsum board is used in dry areas that are not exposed to moisture or vapors, such as bedrooms, living rooms, and hallways. It is also ideal for implementing suspended ceilings and wall formations that do not require special resistance to weather factors.
It should also be mentioned that the paint layer on white gypsum board will somewhat protect it from vapors in the bathroom, but continuous exposure over months and years will make it weak and unusable.
Advantages of Green Gypsum Board and Why it is Preferred in Kitchens and Bathrooms?
Green gypsum board differs from the regular type by adding chemical materials such as silicone and fiberglass inside the gypsum core, and it is covered with green cardboard resistant to water absorption. These specifications give it the ability to withstand high humidity and rising water vapor.
The uses of this type are concentrated in “wet” areas inside the home, most notably kitchens and bathrooms. It is also recommended for use in coastal areas where humidity levels are higher, to prevent the appearance of mold or peeling paint over time.
Green gypsum board also has the ability to withstand water leaks for several hours before it starts to disintegrate, giving you the opportunity to discover and correct the problem before it escalates. As for white gypsum board, it starts absorbing water immediately, which will cause it to disintegrate within a few minutes, requiring complete replacement.
Steps to Inspect Gypsum Board Quality Before Purchase and Installation
To ensure you get a product that meets engineering specifications, you must perform the following checks:
- Thickness Check: Ensure that the board thickness is 12.5 mm (which is the standard for wall and ceiling panels).
- Cohesion Test: Press your finger on the corners of the board; if the gypsum crumbles easily, this indicates poor quality or improper storage.
- Cover Inspection: The outer cardboard must be completely adhered to the gypsum without any air bubbles or detachments.
Learn About Red and Blue Gypsum Board and Their Special Uses
In addition to white and green, special types are available for harsh conditions:
- Red Gypsum Board (Fire-Resistant): Contains dense glass fibers, and is used in generator rooms, commercial kitchens, and areas requiring high protection against fire spread.
- Blue Gypsum Board (Dual-Resistant): This is the strongest type, as it combines moisture resistance and fire resistance properties simultaneously, and is often used in hospitals and large projects that apply international safety standards.
By choosing the appropriate type for each environment, you ensure the preservation of your home’s aesthetics and avoid future maintenance costs resulting from poor selection.
