What can I do about our drafty doors?

by Sarah
We have three drafty fiberglass doors in our 500 sq. of downstairs living. One is used as the actual front door. The other door that used to go to an upstairs unit that is now our bedroom/laundry space we are keeping because that is the only access to the upstairs (there is an opening from the downstairs living, but to move it's easy because it's at the bottom of the stairs). And lastly across the room (25 ft approx. away from entry door) is our back door that NEVER gets used. We haven't done anything with our back door so it has to stay for when we finally finish that. But with all these doors they are extremely drafty! We have almost a half inch gap between the door jams and the door. What products can we use to close off these gaps?
