Blow-Out Barn Door
"Maybe someone can use this idea," says LaVern Henderson, Ettrick, Wis., about the blow-out door he installed on his 50 by 22-ft. loafing shed which has an open south end.
"I installed the blow out door on the back side. The door is 4 ft. by 20 ft. and folds down when the wind is blowing into the barn and reaches speeds of 25 mph or more. It is counter weighted and will close when the wind dies down. This door releases the wind pressure, preventing stress on the building and would prevent the roof from blowing off in extremely high winds."
