Green Board Drywall & Cement Board
Have you considered green board or cement board installation for your home? Help protect your walls from water damage with green board or cement board drywall.
Unlike standard drywall, which is prone to water penetration and damage, green board and cement board are designed to better endure some moisture exposure. While not waterproof, green board and cement board are moisture-resistant and often installed in areas of the home where occasional moisture is expected, such as bathrooms and basements.
Standard drywall is made of the mineral gypsum. Gypsum is mixed with water, starch and paper pulp to create sheetrock. The sheetrock is then surrounded by a paper covering. When water penetrates sheetrock, it causes the sheetrock to lose firmness and crumble, and may even lead to mold and mildew growth. The best way to repair water-damaged drywall is to replace it.
Green Board vs. Cement Board
Green Board Drywall
Green board is a type of drywall with a different paper front and back than standard drywall. The paper covering on green board contains water-repellent additives that prevent water from penetrating gypsum sheetrock. Green board is often used in areas of the home expected to experience higher levels of humidity or moisture, like laundry rooms and bathrooms.
Green board drywall is not waterproof, but rather water-resistant. Excessive water penetration eventually will damage green board as much as standard drywall. That said, green board drywall will offer some level of protection in humid environments.
Cement Board Drywall
Cement board is a type of drywall composed of cement and a glass-fiber mesh covering. It is highly durable and more water-resistant than green board. Cement board is typically used in areas of the home expected to experience significant, direct water exposure.
Areas Prone to Moisture
There are areas in your home that are more prone to high levels of moisture and would benefit from drywall green board and/or cement board installation:
Laundry and Mud Rooms
Laundry rooms typically have higher levels of humidity, and splashing from the laundry sink can expose walls to additional moisture.
Steam from showers and baths and splashing from showers and sinks expose bathroom walls to higher levels of moisture. Drywall behind showers and tubs may experience significant, direct water exposure.
Hot Tub Rooms
Steam from hot tubs exposes walls to high levels of moisture. Walls may experience significant, direct water exposure.
Basement humidity levels are affected by outdoor humidity levels. Since warmer air carries more moisture, the relative humidity of basements often rises during summer time, exposing walls to additional moisture.
Indoor pools are often heated, exposing walls to high levels of moisture. Significant, direct water exposure is likely to occur.
Closed closets have restricted air airflow and retain higher levels of humidity. Bathroom and basement closets are particularly known for having higher levels of humidity and moisture.
Green Board & Cement Board Installation
For areas prone to high humidity and moisture, green board installation is recommended. The price difference between standard drywall and green board drywall is insignificant, and the added protection of installing green board far outweighs the price of replacing water-damaged drywall.
For areas susceptible to excessive and repeated water exposure, cement board often is installed (green board is sometimes used as well). Since cement board is not made of gypsum, it is less likely to break down from water exposure or allow mold or mildew growth. Even though cement board installation is more expensive than both standard drywall and green board drywall installation, it can withstand significant, direct water exposure.
