Turning my garage into a workshop without converting door to wall -
Current door has some insulation but has lots of places where air gets through on top, bottom, sides and joints. Want to add extra layer of insulation panelling (about 1" space where this can be fit), replace bottom weather strip and weather strip top and sides. Any suggestions? Can get new door for just under $1000 with 17.5 R value installed with bottom & side weather seals at no additional cost.
