Energy Loss Calculator for Traffic Doors

Every open doorway allows for air to flow through. A strip door blocks at least 65% (conservatively) of air passing through a doorway. The Result? Strip Doors = Energy Savings. With less conditioned and/or heated air escaping through open doorways energy costs will go down.

The calculator below will show you the daily cost of each open doorway – thus how much money you'll save every single day by installing a Save-T Solutions strip door.
