A slab door is a standalone door without a frame or hardware. A prehung door is a complete set that includes the door, frame, hinges, and sometimes the doorknob and lockset.

In most cases, a prehung door is the better and easier option to install, especially for DIY projects or exterior applications, as they often come pre-weatherproofed. They require fewer tools and less experience to install properly. Although prehung doors are heavier and have a higher upfront cost, the investment is often worthwhile for a complete upgrade that includes a new frame.

A slab door may be a better choice if you are on a tight budget, have a custom-sized wall opening, or only need to replace the door while keeping the existing frame. While the initial cost is lower, you will need to purchase all the hardware separately and do more DIY work to hang it, which may not result in significant time or money savings.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

Kick plates can absolutely be installed on metal doors. Many kick plates for metal doors are magnetic to avoid needing to drill into the metal, but many door manufacturers make kick plates that can be traditionally installed on metal doors using screws. Consult the manufacturer’s instructions to see which is recommended for your door model.

Outswing doors are more popular for exterior doors as they offer more room for moving items in and out of a home. And because the hinges are on the outside of the door, they’re more secure against potential break-ins. But, outswing doors are more susceptible to the elements and are more expensive. Comparing inswing vs. outswing doors depends on your budget, needs, and overall preference.
