Issues of controlling bacteria in closed environments have become a prevalent topic for indoor air quality

With the COVID-19, issues of controlling bacteria in closed environments have become a prevalent topic for indoor air quality for occupant comfort. The most common recommendation for soundproofing of duct-work and to thermal resistance to heat transfer and loss of energy is sound lining, but this is also the ultimate nursery for accumulation and propagation of air-borne bacteria through transmission bacteria via exhale/inhale of occupant breath. We recommend consulting with your engineer if you believe it is prudent to remove sound lining while there is time and to seek optimum measures for soundproofing and resistance to heat transfer associated with HVAC duct-work in your project.

COVID-19 outbreak and extended quarantine directs attention to indoor air quality and possible ways of improvement. MEI leads these efforts and seek optimum measures for soundproofing and resistance to heat to promote human health.
