Project Snapshot
- Location: Stamford, Connecticut
- Project: 100 Elmcroft Commercial Development
- Application: Low-pressure HVAC duct system installation
- Contractor: J Marasco Heating and Cooling, LLC
- Wholesaler: Distribution International
- Product Used: GreenSeam Plus snap-lock pipe
The Challenge
The 100 Elmcroft project involved a large-scale commercial duct installation under tight scheduling and code compliance requirements. With the majority of the work performed overhead on ladders, scaffolding, or lifts, the contractor sought a product that could reduce time spent in elevated and potentially hazardous positions, while also improving installation efficiency and system performance.
The Solution: GreenSeam Plus Snap-Lock Pipe
The GreenSeam Plus snap-lock pipe provided a built-in, factory-applied gasketed seam that eliminated the need to manually seal joints in the field. This not only improved installation speed but significantly reduced exposure to risky jobsite conditions.
Results & Impact
- Labor Time Saved: Over 200 hours saved on overhead work
- Cost Savings: More than $14,000 in reduced labor costs
- Safety Benefit: 200 hours removed from elevated, high-risk work areas
- Install Speed: Up to 40% faster than traditional-sealed snap-lock pipe
- Leakage Control: Airtight seal helped meet Connecticut energy codes with ease
- Product Reliability: Long-term system performance, no callbacks required



Enhanced Safety on the Jobsite
By eliminating the manual application of sealant at every joint, GreenSeam Plus reduced installer time on ladders and lifts, significantly lowering the risk of falls and repetitive motion injuries. 200 hours of labor were shifted away from dangerous elevated positions, improving both jobsite safety and morale.
“GreenSeam Plus didn’t just save us time—it made the job safer. We eliminated over 200 hours of elevated labor, which greatly reduced our risk exposure. Add in the $14,000 in labor savings and the airtight performance, and this product is now our go-to for all ductwork installs. And finally, the comfort it brings local engineers and inspectors knowing we use GreenSeam Plus is worth its weight in gold.”
