We had planned to have a sliding barn door installed on our new barn but are having second thoughts due to sliders not being weathertight or critter proof. The builder has suggested a garage door type affiar but we REALLY dislike garage doors,mainly because they aren't very 'barn-like'... We thought of having 2 swinging barn doors in place of the slider,what do y'all think? The builder says they will sag eventually and require replacement of the hinges. The doors would each be 41/2 feet wide and 9 feet tall. Thanks.
