If you prefer the natural look of wood for your entry door, JELD-WEN offers a selection of 20-minute fire-rated doors with a 1 3/8-inch fire-resistant core. Proper weather stripping is recommended no matter what type of door you go with, whether it's made of alder, like this two-panel model, or steel. A sweep on the bottom of the door, for instance, will help prevent smoke from entering the house and will provide more energy efficiency throughout the year. Alder door, $807. JELD-WEN Inc.,
