Improve your buildings' Ventilation

Your building’s leaky ventilation shafts are wasting energy, costing you money, and greatly reducing indoor air quality.

Poor building ventilation is a critical issue. Research has clearly linked faulty building ventilation to higher energy costs, added maintenance costs, chronic health issues, reduced worker productivity, increased absenteism, and indoor comfort problems.

Common Signs of Poor Ventilation Include:

Persistent Mold & Mildew – Especially in Bathrooms

Chronic Odor Issues

Higher than Normal Energy Bills

High Rate of Worker Illness

Aeroseal: An easy solution to poor ventilation

Most buildings today are plagued with poor ventilation because there hasn’t been a practical, effective way to seal these leaks. With most ventilation ductwork hidden behind walls or otherwise hard to access, finding and sealing the leaks was too expensive and too disruptive to consider. So for decades, ventilation issues were simply ignored.



Aeroseal duct sealing technology changed that. Sealing the leaks causing poor ventilation is now a straightforward, cost-effective process. Since a fog of aerosolized sealant is applied from the inside of the pressurized ductwork, finding and sealing leaks is done without disruption to existing structures. Projects can often be completed as quickly as a single afternoon and a computer-generated report shows the before and after results.
