What is the purpose of tie straps in ductwork?

Tie straps in ductwork serve the essential function of fastening ducts together. Properly securing ducts is critical for maintaining the integrity of the HVAC system. This fastening helps prevent air leaks, which can lead to inefficiencies in heating and cooling, increased energy costs, and decreased system performance.

Using tie straps ensures that the ducts remain in place, providing a stable framework for the entire ventilation system. Effective fastening supports the overall design, allowing air to flow freely and efficiently throughout the building. In addition, stable duct connections can reduce noise associated with rattling or vibrations that may occur if ducts are not secured properly.

While supporting insulation and connecting ducts to fans might seem relevant, those processes typically involve different methods and materials tailored for those specific purposes. Thus, the role of tie straps is strictly related to securing ducts rather than insulation support or fan connections.
