DensShield vs Green Board: Which is Better for Your Project?

When planning a construction or renovation project, choosing the right materials is crucial. Two popular options for moisture-resistant wall boards are DensShield and Green Board. Let’s explore what each material is, their advantages, and the best applications for their use.

What is DensShield?

DensShield vs Green Board

DensShield is a type of gypsum board designed to resist moisture. It has a unique construction with a water-resistant core covered by a fiberglass mat. This combination makes it more durable and moisture-resistant than traditional drywall.

DensShield Tile Backer is perfect for tiling interior walls, ceilings, home and light commercial floors, and countertops in wet areas like bathrooms, showers, kitchens, laundry rooms, pool areas, and locker rooms.

Advantages of DensShield

Moisture Resistance:

DensShield is highly resistant to water, making it perfect for areas exposed to moisture, like bathrooms and kitchens. The board is kept safe from water damage with a core that resists moisture and a surface made of fiberglass. This feature significantly reduces the risk of damage from water exposure, making it a reliable choice for wet areas.

Mold Protection:

The fiberglass surface of DensShield prevents mold growth, promoting a healthier indoor environment. Mold can cause a variety of health issues, including respiratory problems and allergies. Choose DensShield to lower mold risk, improve indoor air quality, and create a safer home for you and your family.


DensShield is sturdier than regular drywall and can withstand more wear and tear. This durability means that it will last longer in areas that experience high traffic or heavy use. Unlikely to get dents, scratches, or other damage that can ruin the look and function of regular drywall.

Ease of Installation:

DensShield is easy to cut, handle, and install with standard tools. It is lightweight and users can easily transport it to the installation site. It is easy to install, saving time and effort for construction projects. It is a popular choice for both professionals and DIY enthusiasts.

Applications For DensShield


DensShield is ideal for shower walls and tub surrounds due to its excellent moisture resistance. In these areas, it provides a reliable barrier against water, preventing it from penetrating the wall structure. This helps to prevent issues like rot and deterioration of the building materials behind the wallboard. Its mold-resistant properties also contribute to a healthier bathroom environment.


In kitchens, DensShield is perfect for areas near sinks or where spills are common. Its water-resistant properties protect the walls from splashes and spills, ensuring that the kitchen remains in good condition. It is also a good choice for backsplashes and other areas that may come into contact with water or steam from cooking.

Laundry Rooms:

Laundry rooms often experience high humidity levels due to the presence of washing machines and dryers. DensShield is a great choice for these spaces because it can withstand the moisture and humidity, preventing damage to the walls. It helps to create a durable and long-lasting wall surface that can handle the demands of a busy laundry room.

What is a Green Board?

Green Board is a type of drywall that is treated to resist moisture. It gets its name from the green paper covering that indicates its water-resistant properties. While it is not as moisture-resistant as DensShield, it is still a better option than standard drywall for damp areas.

Advantages of Green Board


Green Board is generally less expensive than DensShield, making it a budget-friendly option. For projects where cost is a significant concern, Green Board provides a good balance between affordability and performance. It allows you to achieve better moisture resistance than standard drywall without breaking the bank.

Moisture Resistance:

Green Board offers better moisture resistance than regular drywall, though not as much as DensShield. It is treated with special additives that help it to resist moisture, making it suitable for use in areas that experience occasional dampness. While it may not be as effective as DensShield in very wet environments, it is still a better option than standard drywall for areas with moderate moisture.

Ease of Use:

Green Board is easy to cut and install with common drywall tools. Its installation process is similar to that of standard drywall, making it a familiar material for contractors and DIYers alike. This ease of use can help to streamline construction projects and reduce labor costs.

Applications For Green Board


Basements can be prone to moisture issues due to their location below ground level. Green Board is suitable for walls in basements where moisture levels are moderate. It provides a good level of protection against dampness, helping to prevent mold growth and structural damage. However, for basements with significant water issues, additional waterproofing measures may be necessary.


While DensShield is a better choice for areas directly exposed to water, Green Board can be used in bathroom areas that are not directly exposed to water, such as ceilings and walls away from the shower or tub. It provides a cost-effective way to improve moisture resistance in these areas without the higher expense of DensShield.


Green Board is a good option for kitchen walls and ceilings that are away from direct water sources. It helps to protect the walls from humidity and occasional splashes, ensuring that the kitchen remains in good condition. It can also be used behind cabinets and appliances to provide an additional layer of moisture protection.

DensShield vs. Green Board: Which to Choose?

When deciding between DensShield vs. Green Board, consider the specific needs of your project. If you need high moisture resistance and durability, DensShield is the better choice. It is especially effective in high-moisture areas like showers and tub surrounds. On the other hand, if you’re looking for a more budget-friendly option for areas with moderate moisture, Green Board can be a suitable choice.

DensShield vs Green Board

Moisture Resistance:

DensShield offers superior moisture resistance compared to Green Board. Its unique construction with a water-resistant core and fiberglass mat surface makes it more effective at preventing water penetration. This makes it the best choice for areas that are frequently exposed to water, such as shower walls and tub surrounds. Green Board, while more moisture-resistant than standard drywall, is not as effective in very wet environments. It is better suited for areas with occasional dampness or moderate humidity.

Mold and Mildew Protection:

DensShield provides better protection against mold and mildew due to its fiberglass mat surface. Mold and mildew thrive in damp environments, and the water-resistant properties of DensShield help to create a barrier that prevents their growth. This makes it a healthier option for indoor spaces, particularly in areas prone to moisture. Green Board also offers some mold resistance, but it is not as effective as DensShield in preventing mold growth.


DensShield is more durable than Green Board. Its sturdy construction allows it to withstand more wear and tear, making it a better choice for high-traffic areas. It is less likely to suffer from dents, scratches, and other damage, ensuring a longer lifespan. Green Board, while more durable than standard drywall, does not offer the same level of durability as DensShield.


Green Board is generally more cost-effective than DensShield. For projects with a tight budget, Green Board provides a good level of moisture resistance and durability at a lower cost. However, for areas where high moisture resistance is critical, the additional investment in DensShield can be worthwhile to ensure long-term performance and protection.


Both DensShield and Green Board are relatively easy to install with standard drywall tools. However, DensShield’s lightweight construction and ease of handling can make it a more convenient option for larger projects. Its installation process is straightforward, helping to reduce labor costs and project timelines.

Bottom Line

Green Board is water-resistant and better than regular gypsum, but cement board is the best choice. For shower or tub surrounds, I use DensShield, which is much better than Green Board. However, for walls and backsplashes with minimal water exposure, Green Board works fine.

Green Board provides a cost-effective and practical solution. Always consider the environment where the material will be used and choose accordingly.

By carefully evaluating the needs of your project and the specific properties of DensShield vs Green Board, you can select the best material to ensure long-lasting performance and protection.
