Local Business uses Breakthrough Duct Sealing Technology to Reduce Ventilation Leakage from 357 CFM to 21 CFM
Restoring old buildings is a practice that keeps the history of great places alive. This much was certain in the restoration of old St Albans church in Ottawa. The church has existed since 1868 and was designed by the same man who built Ottawa’s iconic Parliament Building. With the times the church has updated its interior including adding ventilation. Unfortunately it was incredibly leaky. The leakage was equal to there being a 68 square inch hole in the ventilation. The church decided to call in AWS Remediation to improve their heat distribution and efficiency. The problem with older buildings is they are incredibly drafty, couple that with a leaky air duct system and you have a recipe for discomfort.
In Brief
Building: St. Albans Church
Engineer: Dolyn Development
Duct Specialists: AWS Remediation
Technologies
Goal: Eliminate duct leakage caused by old technology
Before Aeroseal: Up to 375 CFM
(cubic feet per minute) of leakage
After Aeroseal: 21 CFM of leakage
The only problem with sealing ducts the traditional method is that it can be messy, costly and disruptive. The church has to have services and there is very little money that comes into a church. Destroying the walls to access the vents would have been catastrophic. AWS came in and sealed the vents all within a couple of hours.
With the vents sealed, the church was able to effectively heat itself and cut down its power bill by a substantial margin and reducing the leakage in their ducts by 94 per cent, showing that not only can Aeroseal help newly developed projects, it can also serve to save those older buildings from the frigid winters of Canada.
