If you're selecting drywall for home construction, renovation, or another project, take a look at purple drywall versus green drywall to see which makes sense for you.
Purple drywall and green drywall, while both specialized variants of traditional gypsum board, exhibit key differences in their applications and properties. Purple drywall, also known as mold-resistant drywall, has been engineered to hinder the growth of moisture and mold.
Green drywall, often referred to as greenboard, resists moisture to a lesser extent than purple and is ideal in rooms that have occasional moisture exposure, like laundry rooms. While both types provide superior moisture resistance in comparison to traditional drywall, their specific use depends on the amount of moisture protection required for a given room.
Purple drywall is a specialized type of gypsum wallboard that effectively resists moisture and mold growth. Its use is mainly in rooms vulnerable to high humidity levels, such as bathrooms and kitchens. Moisture-resistant paper facing and a specifically designed gypsum core constitute purple drywall, making it a necessary option for preserving wall longevity and structural integrity in environments exposed to dampness. The distinctive purple color is used to differentiate it from regular drywall, serving as a visible indication of its resistance to moisture.

Purple drywall’s enhanced durability makes it less susceptible to sagging or deterioration, particularly in humid conditions. Purple drywall naturally features fire-resistant properties, making it a safe choice for use in both residential and commercial buildings. Another added benefit of purple drywall is its natural soundproofing abilities.
While there are exceptional benefits to using purple drywall, it does come with some drawbacks. One of the primary concerns is the cost. Purple drywall is typically more expensive than standard drywall. Its limited availability can also create a roadblock for construction, especially in remote areas where sourcing it may be challenging. This could potentially lead to delays or increased transportation costs.
The effectiveness of purple drywall’s moisture resistance hinges on correct installation, which means you’ll need a skilled drywall installer. Compared to standard drywall, the increased weight of moisture-resistant drywall makes suitable framing and support essential during installation, leading to more complicated construction projects that may demand additional labor and materials.
Green drywall is another type of gypsum board designed for use in areas with elevated humidity levels. It features a water-resistant paper covering that distinguishes it from standard drywall and provides a certain level of protection against moisture, although it is not entirely waterproof.
Greenboard is particularly useful for preventing water damage and mold growth in spaces prone to occasional splashes or dampness. However, it should not be used in areas that are consistently exposed to standing water, as it does not provide the same level of moisture resistance as purple drywall.
