Benefits of Spiral Duct

Energy Efficient. Easy to Install. Looks Great.

Why Spiral Duct?

Ductwork leakage is often cited as a significant source of causing the most additional energy use in the built environment. Eastern Sheet Metal's spiral pipe systems minimize the amount of leakage through the design of their duct seams and connections, reducing energy waste.

Duct Seams

Spiral seams require no sealing and this is recognized by ASHRAE Standard 90.1. ESMs AMCA testing proves out the ASHRAE standard regarding seams - the testing shows leakage rates so low as to be inconsequential.*

Duct Connections

Spiral duct is provided in lengths up to 12’ long. Because of this length difference, and taking into consideration the number of fittings required, 30% or more of the field connections can be eliminated. Careful use of factory mounted branches on spiral duct can allow the elimination of almost 50% of field connections. In other words, the use of spiral can eliminate the opportunity for leakage by almost half.*
