Ventilation is the key for #Covid19

Dear Readers, 

Hope everyone is staying safe & well. After reading many scientific articles over covid19 now most of the people is accepting it as a fact that covid19 transmission is airborne rather than by hands or, surface touch. Further studies suggest that One can easily catch Covid19 virus in poor ventilated closed space.



Quite in detail explanation- How infection spreads in Closed space


What is micro droplets & how it remain suspended in closed room or, space.


Must watch video to understand severity of danger while interacting in closed space.







I was strong advisor for Casement or, openable Door/window rather than Sliders. (Are aluminium sliding windows soundproof?) but being an old veteran in the industry as well as after losing few loved ones by this disease, I realized & recommend to everyone not to remain in air-tight meeting spaces as well as avoid meeting places where ventilation is poor. 

You can have one sound proof or, noise-safe room for study or, meditation with openable or, casement but let your all other spaces should have cross-ventilation or, use Sliders instead of Casement or, openable.

    1. Frankly speaking in my opinion, avoid air-conditioner till peak of this pandemic is over. If needed then use it alone or, use it with trusted people or, your immediate family. Avoid sharing air with unknowns. Try to spend most of your time in cross-ventilated room.

      It is proven scientifically micro-droplets remains 45 minutes in air in 1-point ventilation room but clears within 7 min in 2-point ventilation. Watch following link https://www.youtube.com/watch?v=59tQeL0ehbM

  4. Hi Anish,

    Thanks for pointing out it. In my entire 14 year career in Fenestration industry, I tried to convince people to choose Casement or, Openable over sliders. As it has better air tightness than in Sliders so you will get better noise & dust insulation. But Covid19 redefined the rules of air tightness for closed spaces. Imagine a meeting or, conference room with openable or, casement windows where there is more chance to get infected with covid19 when you exchange air with strangers due to suspended aerosol or, micro droplets. In Sliders, due to brush seal, it creates effect of trickle vent or, it helps upto some point for cross-ventilation. My recommendation to use Sliders instead of Openable or, Casement in Living or, meeting spaces. I hope that i have answered your query.
