Case Study: University Sports Arena

Engineers overcome 55 year old venue’s HVAC equipment space limitations and design/installation challenges with new 60 inch diameter fabric duct. The consulting engineer/architecture firm spearheading the HVAC portion of the $72 million renovation found that fabric duct, which was 90% lighter than metal duct, was the solution to both the project’s roof load-bearing limitations along with the many added advantages of fabric compared to the metal alternative.

SkeleCore Pull-Tight Fabric HVAC Ductwork

SkeleCore Pull-Tight is a suspension/retention system for fabric ductwork utilizing a combination of internal hoops and tensioning baskets to help maintain fabric shape. SkeleCore's Pull-Tight technology supports the fabric with 360 degrees of tensioning eliminating noise, sagging, and wrinkles. SkeleCore Pull-Tight can be suspended from either a tension cable or track suspension system and is tensioned "externally" utilizing a tension cable lock. Pull-Tight improves startup performance and aesthetics when compared to multiple row, horizontal suspension systems.
