do you think that adding an entrance shelter to a building could help with the cold air coming in in the winter time. im thinking of one of those tarp/plastic removable ones. this is a high traffic area where a door is opening and closing and staying open for 60 seconds. the whole room fills with a gust of wind and cold air. i am thinking if a vestibule was installed outside it would help the situation. (this is work, not home)

Called an air lock, works wonders if semi air tight and one door can't be accessed with the other open. Keeps people out front much happier and will make a marked difference in heat cost.
