Exchange a screen door for a metal walk door
I have a solid interior door at an animal shelter. Due to uneven temperature regulation the room is either too cold in winter or too hot in the summer. The HVAC company installed some more ducts and ceiling vents but there is no easy way to add an effective return. My solution is to swap out the solid door for a pet screened door. The existing door is ~1 3/4" thick and the screen door appears to be about 1". Should I sister a 1x4 around the edge of the door to allow use of the existing hinges, frame, and lock hardware or is there a better way? Being a shelter, we need to be on the cheap.
