Wooden doors cost 300 wood and have 200 hitpoints. They have no weak side. Open doors seem to have the same strength as closed doors. Hitting the lock on a door often deals no damage.

• Molotov: 138dmg (100 fuel (2x molotovs))
  
• Flamethrower: 0.6dmg - 1.9dmg (113 fuel)
  
• Chainsaw: 3dmg (67 fuel)

Notes:
The flamethrower starts a fire after a burst of 13 fuel. Don't be too close to the target or you'll burn yourself. The longer the burst, the more damage it generally inflicts per fuel spent. A full burst of 100 fuel should nearly burn the door down, so a final burst of 13 fuel should finish it. The Chainsaw seems better suited to resource-gathering than raiding, and after an update it now wears down quickly against doors.

An easier way to get through the door would be to destroy the doorframe with certain weapons if the frame was wooden or badly damaged. The weak side of a wooden door frame is fairly easy to break through with melee weapons or tools. If the door has no lock then you can open it and hold down the use key to pick it up (you'll probably need a hammer in hand). The wooden double door shares the same hitpoints as the single wooden door.
