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.
