CertainTeed's Flintlastic roofing systems represent a modern approach to low-slope roofing, emphasizing performance, sustainability, and ease of installation. These systems are designed to meet the needs of residential and commercial applications, offering flexibility in design, durability, and energy efficiency. This article provides an in-depth overview of the Flintlastic product line, highlighting key features, materials, and components relevant to installation processes.
Overview of Flintlastic Roofing Systems
Flintlastic is a family of low-slope roofing systems developed by CertainTeed, engineered to deliver long-term protection and performance. These systems are composed of SBS-modified bitumen membranes that are either self-adhered or torch-applied, depending on the specific product variant. The SBS modification enhances the flexibility and resilience of the bitumen, making it more suitable for temperature fluctuations and structural movement.
The Flintlastic product line includes multiple configurations tailored to different performance requirements. The SA (Self-Adhered) series is designed for speed and affordability, while the GTS-FR (Granulated Torch-Apply Fire Resistant) variant is used when a Class A fire rating is necessary. Both systems are available in various surfacing options, including CoolStar, which improves solar reflectivity and contributes to energy efficiency.
The Flintlastic SA system, in particular, emphasizes S.A.F.E. roofing—Speed, Affordability, Fume & Flame Free, and Easy to Learn. These attributes make it an appealing option for residential and commercial applications where efficiency and environmental considerations are key.
Key Components and Material Specifications
The Flintlastic roofing systems are constructed using a combination of base sheets, interply membranes, and cap sheets. These components are designed to work together to provide a durable, weather-resistant roofing solution.
Base Sheets and Interply Membranes
The base sheet and interply components form the foundational layers of the Flintlastic roof system. These layers are responsible for bonding the system together and ensuring structural integrity. The SA series uses self-adhered base sheets and interply membranes, which are applied without the need for torches or solvents. This eliminates the risks associated with fumes and open flames, enhancing safety during installation.
The SA system includes several base sheet options:
- Flintlastic SA PlyBase is the standard self-adhered base or interply sheet used in most applications.
- Flintlastic SA MidPly is a premium variant that is recommended for applications where 20-25-year warranty coverage is desired.
- Flintlastic SA NailBase is used when mechanical attachment of the base sheet is preferred.
These base layers are manufactured using SBS-modified bitumen with a resilient polyester reinforcement, ensuring durability and resistance to weathering.
Cap Sheets
The cap sheet serves as the top layer of the roofing system and is responsible for providing protection against UV radiation, weathering, and fire. Flintlastic offers several cap sheet options, each tailored to specific performance needs:
- Flintlastic SA Cap is the standard cap sheet in the SA series, designed for general durability and weather resistance.
- Flintlastic SA Cap CoolStar is a variant that includes highly reflective surfacing, improving solar reflectivity and reducing heat absorption.
- Flintlastic SA Cap FR adds fire and impact resistance to the self-adhered system, making it suitable for applications requiring enhanced safety features.
- Flintlastic SA Cap FR CoolStar combines fire resistance with high solar reflectivity, offering a dual-performance option for energy-conscious and fire-rated applications.
In the GTS-FR series, the cap sheet is a granulated, torch-applied SBS-modified bitumen product with fire-resistant additives. This system is ideal for applications requiring a Class A fire rating.
Installation Considerations and Recommended Accessories
The installation of Flintlastic roofing systems involves specific techniques and accessories to ensure optimal performance. The SA system is self-adhered, meaning it is applied without the need for additional adhesives, torches, or solvents. This method is generally faster and safer than traditional torch-down methods.
To support the installation process, CertainTeed recommends the use of certain accessories:
- FlintPrime Aerosol is a spray primer used for small detail areas, such as edge metal and tops of metal fasteners. This helps ensure proper adhesion in critical locations.
- Mechanical fasteners may be used in conjunction with the SA NailBase option for applications where mechanical attachment is preferred.
For the GTS-FR system, torch-down technology is utilized, which involves heating the membrane to activate the adhesive layer. This method requires experienced labor and proper safety precautions due to the use of open flames.
Regardless of the installation method, it is essential to follow manufacturer guidelines and local building codes to ensure compliance and long-term performance. Proper preparation of the substrate, including cleaning and drying, is a critical step in the installation process.
Performance and Sustainability Features
Flintlastic roofing systems are designed with a focus on performance, longevity, and environmental responsibility. The SBS-modified bitumen used in these systems provides enhanced flexibility and durability, making it suitable for a wide range of climates and conditions.
One of the notable sustainability features of the Flintlastic SA system is the availability of CoolStar surfacing. This reflective coating helps reduce the radiant solar heat absorbed by the roof, contributing to lower energy consumption and improved indoor comfort. For buildings located in warmer climates, the use of CoolStar surfacing can lead to measurable energy savings over time.
In addition to energy efficiency, the self-adhered nature of the SA system reduces the environmental impact associated with traditional roofing methods. The elimination of solvents and torches not only improves worker safety but also reduces emissions and hazardous waste.
Warranty and Long-Term Value
CertainTeed offers warranty options for Flintlastic roofing systems, depending on the specific product and installation method. The SA MidPly variant, for example, is recommended for applications where 20-25-year warranty coverage is desired. This underscores the importance of selecting the appropriate product for the intended use and environmental conditions.
The overall value proposition of Flintlastic systems lies in their combination of durability, ease of installation, and long-term performance. Whether applied as part of a new construction project or a roof replacement, these systems are designed to provide reliable protection for decades.
Conclusion
CertainTeed's Flintlastic roofing systems represent a comprehensive solution for low-slope roofing applications, offering a balance of performance, sustainability, and ease of installation. With a range of product configurations and surfacing options, these systems can be tailored to meet the specific needs of residential and commercial projects. The emphasis on S.A.F.E. roofing principles further enhances their appeal, particularly in applications where speed, affordability, and safety are critical factors.
For installers and property owners, the availability of detailed technical data sheets and manufacturer guidance ensures that installations can be carried out with confidence and precision. As the roofing industry continues to evolve, the Flintlastic product line remains a testament to innovation and reliability in the field of low-slope roofing.
