Discussion and Conclusions
The time saving benefits of using the Speedi Boot assembly were easily observed in comparing
this system with the conventional, established techniques of blocking and inserting the standard
HVAC boot. Because of the opportunity to omit the preparation of the installation site by
blocking and adapting, ease of application using the Speedi Boot was demonstrated consistently.
Adaptability and final appearance was judged, preferred.
To a significant degree it was felt that the percentage of air loss (lower pressure
differential) could have been affected positively by using mastic to seal the irregular
interface created by crimping the boot assembly to the duct in its adaptation to the
Speedi Boot (B. above). However, even in the absence of that consideration, the
greater pressure differential when using the Speedi Boot application, compared to the
conventional techniques, demonstrated the superior resistance to air loss of the Speedi
Boot system.
The failure resistance of the factory installed, dust and debris covers (when subjected to a 6 hour,
75 pascal exposure), proved very impressive. From the performance in this demonstration, we
would anticipate consistent, credible results when carefully conducting duct pressure tests.
In conclusion, both the concept and performance of Speedi Boot have demonstrated features to
recommend its application and advantage over the conventional techniques for installation of the
HVAC boot. We can, with conviction, say that we see serious potential for this product in the
HVAC industry.
