Revolutionizing Safety: Carlisle’s SealTite™ PRO HFO Achieves Groundbreaking 1-Hour Fire Rating
April 2024
In the rapidly evolving metal building market, the drive towards safer, more resilient construction materials has led to remarkable innovations, particularly in the realm of insulation. Carlisle Spray Foam Insulation (CSFI) has once again positioned itself at the forefront of this industry evolution by becoming the first U.S. manufacturer to secure a 1-hour fire rating for spray foam insulation in a new metal building system. This milestone, achieved with SealTite PRO HFO, alongside its Canadian counterpart, SealTite One, represents a significant advancement in building safety standards.
A Leap in Fire Safety
The achievement centers around SealTite PRO HFO and DC-315 Intumescent Coating by International Fireproof Technology Inc. (IFTI), which has been rigorously tested to meet ASTM E119 standards for fire resistance. This makes it a pivotal solution for metal buildings, which traditionally faced challenges meeting fire safety requirements due to their design and construction features.
Metal buildings are inherently prone to air and moisture infiltration, making effective insulation critical. However, achieving a robust fire rating has often required cumbersome and costly methods like the installation of 5/8” gypsum wallboard. SealTite PRO HFO eliminates the need for such measures by providing a direct application solution that maintains both structural integrity and compliance with stringent fire codes.
Why SealTite PRO HFO?
The key to SealTite PRO HFO’s effectiveness lies in its composition and application. The product delivers a seamless, airtight barrier that not only prevents air leakage but also acts as a moisture barrier to protect against corrosion. With high R-values for superior thermal resistance, it helps maintain a comfortable indoor temperature, crucial for the varied uses of metal buildings—from warehouses and workshops to recreational buildings and cold storage.
SealTite One for Canada
In Canada, SealTite One is making similar strides under the national building codes (NBC 2020 and 2015). Tested for a 45-minute and 1-hour Fire Resistive Rating (FRR), this solution allows Canadian builders to achieve required safety standards without the additional structural supports needed for traditional gypsum boards. This innovation not only simplifies construction but also expands the potential for metal building applications in tighter spaces, where fire risks are heightened.
What This Means for the Industry
CSFI’s new fire-rated products offer unmatched benefits:
- Cost-Effectiveness: They remove the need for additional framing and drywall, reducing overall building costs.
- Simplicity: The application process is streamlined, decreasing construction time and complexity.
- Durability and Safety: Enhanced structural integrity and compliance with fire codes make these buildings safer and more durable.
Conclusion
Carlisle’s SealTite PRO HFO and SealTite One are not just products but transformative forces in the metal building industry. By meeting critical fire safety standards in a cost-effective and efficient manner, they are set to redefine the possibilities of metal building constructions. This breakthrough is a testament to Carlisle’s commitment to innovation and safety in the construction sector.
