Following the TAAC meeting on the 20th of September, TightVent partner Mez-Aeroseal set up a small ductwork system at ADEME offices and sealed it. The technology is able to reduce leakages in air duct systems in average by 90%. Aeroseal technology closes the gap between wish and reality in terms of highly efficient air duct systems. To reach air tightness class C or D in an installed system is finally possible and approvable for complete ventilation systems in existing buildings and new constructions. Please follow the links (EN, DE, FR) to specify Aeroseal.
