Stucco Over Densglass: Stucco can be applied over DensGlass Sheathing using paper-backed metal or two layers of building paper and metal lath. Metal lath must be mechanically attached through the DensGlass Sheathing into the steel or wood framing.
Stucco over DensGlass sheathing provides a strong, flat surface for applying a uniform thickness of stucco exterior finish, reducing the potential for wavy wall surfaces. This results in a fire-safe and energy-efficient structure. The system may be applied using either paper-backed metal lath or two layers of building paper and metal lath.
Additionally, Sto Gold Coat over DensGlass panels can be used behind various cladding systems, including exterior insulation systems, stucco over metal lath/building paper, brick, and metal panels. However, DensGlass is not meant to be a permanently exposed external board. It can be exposed for up to twelve months with all joints treated with RCM Tape or FR PRO Sealant during construction.
Benefits Of Using Densglass
DensGlass® sheathing is preferred for construction projects due to its numerous benefits. From fire safety and energy efficiency to waterproof properties and suitability for various claddings, DensGlass stands out as a reliable material for stucco applications.
Fire Safety And Energy Efficiency
One of the notable benefits of using DensGlass sheathing is its exceptional fire safety and energy efficiency features. With a non-combustible core, DensGlass provides a protective barrier and contributes to the overall fire resistance of the structure. Additionally, its energy-efficient properties help reduce heat transfer, providing a more sustainable and comfortable indoor environment.
Waterproof Properties
DensGlass sheathing boasts excellent waterproof properties, making it ideal for exterior applications such as stucco systems. Its resistance to moisture intrusion ensures long-term durability and helps prevent water-related damage, ultimately maintaining the building’s structural integrity.
Suitability For Various Claddings
Another advantage of DensGlass sheathing is its versatility in accommodating various claddings. Whether stucco over metal lath/building paper, brick, metal panels, or exterior insulation systems, DensGlass is a reliable substrate, providing a solid foundation for different cladding materials. This adaptability makes it an attractive choice for various construction projects.
Application Process
Stucco over DensGlass sheathing provides a robust base for uniform exterior finishes, reducing wall imperfections and enhancing fire safety. Applying stucco on DensGlass requires metal lath or building paper for a durable and energy-efficient result, suitable for various cladding options like brick or metal panels.
Metal Lath And Building Paper Application
For applying stucco over DensGlass Sheathing, metal lath and building paper play a crucial role.
Mechanical Attachment Of Metal Lath
To ensure a secure installation, the metal lath must be mechanically attached through the DensGlass Sheathing into the steel or wood framing.
Duration For Which Densglass Can Be Exposed
DensGlass should not be permanently exposed externally. However, with proper joint treatment, it can be exposed for up to twelve months during construction.
Challenges And Solutions
Stucco over DensGlass sheathing offers a sturdy base for applying a uniform coat of stucco, ensuring flat and fire-safe surfaces. This solution involves using paper-backed metal lath or two layers of building paper and metal lath. Additionally, it’s crucial to remember that DensGlass should not be permanently exposed externally.
Limitations Of Densglass As An External Board
DensGlass sheathing offers several advantages as an external board for stucco application. However, certain limitations need to be considered. One limitation is that DensGlass is not meant to be used as a permanently exposed external board. It is designed to be covered with an exterior finish such as stucco.
However, during construction, it can be exposed for up to twelve months with all joints treated with RCM Tape or FR PRO Sealant. Another limitation is that metal lath must be mechanically attached through the DensGlass sheathing into the steel or wood framing when applying stucco over DensGlass. This ensures proper installation and ensures the stucco adheres securely to the sheathing.
Recommended Treatments For Joint Areas
When applying stucco over DensGlass sheathing, it is important to properly treat the joint areas to ensure a durable and seamless finish. Here are some recommended treatments for joint areas:
- RCM Tape: For temporary exposure during construction, joints should be treated with RCM Tape. This helps to seal the joints and prevent moisture infiltration, ensuring the sheathing remains intact.
- FR PRO Sealant: Another option for treating joint areas is to use FR PRO Sealant. This sealant is specifically designed for DensGlass sheathing and provides a robust seal that protects against moisture and air infiltration.
- Metal lath and building paper: When applying stucco over DensGlass, it is recommended to use either paper-backed metal lath or two layers of building paper and metal lath. This provides a solid base for the stucco and helps to prevent cracking and separation.
- Sto Gold Coat: Sto Gold Coat can be a waterproof air barrier over DensGlass panels. It provides an extra layer of protection against moisture infiltration and ensures a long-lasting stucco finish.
By following these recommended treatments for joint areas, you can ensure a successful stucco application over DensGlass sheathing, creating a durable and visually appealing exterior finish.
Conclusion
In conclusion, while DensGlass sheathing offers several advantages for stucco applications, it is important to be aware of its limitations as an external board. Properly treating joint areas with RCM Tape, FR PRO Sealant, and using metal lath or building paper can help overcome these challenges and ensure a successful and durable stucco finish.
Best Practices And Techniques
When applying stucco over DensGlass, following expert recommendations and taking preventive measures during installation are essential. These practices ensure a successful stucco application and contribute to the finished product’s longevity and durability.
Expert Recommendations For Stucco Application
Experts recommend using either paper-backed metal or two layers of building paper and metal lath when applying stucco over DensGlass Sheathing. The metal lath should be mechanically attached through the DensGlass Sheathing into the steel or wood framing. This ensures a strong and secure foundation for the stucco exterior finish.
Preventive Measures During Installation
During the installation process, it is important to remember that DensGlass is not meant to be used as a permanently exposed external board. It should only be exposed for up to twelve months during construction, with all joints treated with RCM Tape or FR PRO Sealant. This prevents any moisture infiltration and maintains the integrity of the DensGlass Sheathing.
Additionally, using Sto Gold Coat over DensGlass panels can provide added protection. This combination can be used behind various claddings, such as exterior insulation systems, stucco over metal lath/building paper, brick, metal panels, and more. Sto VaporSeal™, an air and vapor barrier, can also enhance performance.
Adhering to these best practices and taking preventive measures can ensure a successful stucco application over DensGlass Sheathing. This creates a visually appealing finish and adds fire-safety and energy-efficient properties to your structure.
