Door

Since the Lord of the Rings mod is unlikely to update to Minecraft 1.8 or beyond, and Mevans learned how to make a core mod so that the mod's NPC's are capable of opening wooden doors, a wide variety of new wooden doors was added in. Most of the textures were made by the Polish Noble.

In addition to the normal wooden doors, there are two special doors. One of them is the iron door of vanilla, which can't be opened except by redstone power sources, and is made out of six iron ingots as opposed to wooden planks. The other one is the Dwarven Door, which is made of stone and can't be seen unless the moon is shining on it.

Crafting
All of the mod's doors, with the exception of the Mallorn door, are made on the regular crafting table, with six planks making that respective door.

The Mallorn door needs to be made on the Galadhrim Crafting Table, and requires at least +1 alignment with that faction to craft.

Defense
As stated earlier, most of the mod's humanoid NPC's are capable of opening up doors. While they can't see players or other NPC's though closed doors, they will open them up if they happen across one. Therefore, if you wish to keep NPC's out of an area, you might want to opt for a Gate or fence gate instead.
