The Kountze Memorial Lutheran Church building in Omaha, Nebraska has an unusually rich history, and preserving that history is a top priority for the church’s members. RE-500 was the sealant of choice for this challenging job because it has a low VOC content, applies quickly and easily, seals immediately and completely, dries rapidly and cleans up easily.
In May of 2015, Duke University kicked off a year-long restoration project to rehabilitate the interior and exterior of the Chapel. Pur- Vent, a full-service HVAC cleaning and sealing company with experience in historic restoration projects, was tasked with restoring the entire HVAC system, including 100 feet of underground ductwork.

For an in-depth look at this project, check out the video here.
Using ISAAC and Carlisle HVAC Products’ RS-100 sprayable water-based duct sealant, Air Management Industries thoroughly coated the interior surfaces of the rigid metal ductwork. The job took AMI one shift to complete and the system passed the leakage test the first time it was administered. The leakage was reduced from 970 CFM (18%) to less than 100 CFM (2%).
