We use a new technology for sealing ventilation duct from the inside. The technology was developed in the US in 1994, but didn't reach the European market until 2015. In 2016 ImL Aeroseal started up in Finland, and as of September 1st 2020 we are breaking into the Norwegian market. Our product solves the issues with the traditional sealing of ventilation ducts; using tape and acryllic sealant to try and plug the leaks. Instead we build up a pressure inside the system and inject a small particle gas that finds all the small leakages and seals them. Not only is it faster, but also alot more effective than the previous method, which in turn makes it much more financially beneficent. With a ventilation system that has little to no leakage you extend the life of the engines and maximize the output of the fans. In addition you get cleaner air in the serviced areas. I became a part of this startup because with my 15 years of experience in the ventilation industry I can truly see the advantages of this method to improve the effectiveness of the ventilation systems and enhance the indoor air quality.
