Sure Seal Spiral

Langdon Sure•Seal™ Spiral: The Smart Choice for Ductwork

Introducing Sure•Seal™ Spiral, Langdon’s innovative single wall self-sealing spiral ductwork system designed to streamline installation and enhance performance.

Key Benefits

  • Quick and Easy Installation: Eliminate messy sealers—simply slide the duct pieces together and secure them with gasketed tek screw fasteners (#10-16-3/4). This process saves time and labor costs.

  • Aesthetic Appeal: The self-sealing design provides a polished finish, making it ideal for exposed areas.

  • Versatile Options: Available in both single wall and double wall configurations, with sizes ranging from 4" to 30" in diameter. Options include 26 to 22 gauge materials in galvanized, galvanneal, stainless steel, aluminum, and PCD (polyvinyl coated ductwork).

Advanced Gasket Technology

Our patented dual-lipped EPDM rubber gasket is designed for high performance:

  • Leakage Control: Tested from negative 2" W.G. to positive 10" W.G., achieving a Class 3 seal rating per SMACNA HVAC Air Duct Leakage Test Manual.
  • Thermal Resilience: Suitable for applications ranging from -20°F to 200°F.

Cost-Effective Sealing Solution

Conventional sealing methods, such as tapes and mastic, are often necessary but can be time-consuming and costly. With Sure•Seal™ Spiral, you reduce the need for field sealing, which can lead to substantial savings. Proper sealing at installation minimizes the risk of energy loss, higher utility costs, and the need for costly restorations down the line.

Enhanced Energy Efficiency

The Sure•Seal™ Spiral system significantly improves airtightness, helping to regulate:

  • Energy conservation
  • Humidity control
  • Space temperature
  • Room air movement

By reducing leakage rates, this system not only enhances system efficiency but also supports sustainable practices.

Conclusion

With Sure•Seal™ Spiral, you gain a high-quality ductwork solution that combines ease of installation, aesthetic appeal, and remarkable energy savings. Say goodbye to the challenges of conventional sealing methods and invest in a system that delivers exceptional performance and reliability.
