Despite their beauty wood doors are often prone to problems that vary from warping, sagging and routine maintenance. Fiberglass door, on the other hand, have the genuine look and feel of a wood door without the head-aches. They do not chip, warp, rot or crack and don't require periodic painting. In addition, they are lighter so they're easier on the hinges and don't sag after time. What do you think..is this better or should we stick to the traditional wood.
