A barricade is wood or metal placed onto a door or window as a defense measure. It's useful in controlling how quickly zombies are able to enter an area and is a essential requirement to keeping a house secure while sleeping.

Barricades can be found naturally in the game world where a former survivor has barricaded a house.
Beware that sometimes these houses are full of zombies as the barricades keep them inside as well.
Right click onto the selected door or window and this will bring up a drop down menu where you can choose to "Barricade".
To undo a Barricade
If you wish to remove a wooden barricade, you will need to use a hammer, and you will get wood planks back.
If you wish to remove a metal sheet barricade, you will need to use a welder and welding mask, and once done you will get the metal sheet back.
At this time, (Build 36.40) metal bar barricades cannot be removed.
Strength of Barricades
Wooden Barricade strength is dependent on the wooden plank that has been placed on the window. As the barricade becomes damaged, the planks themselves become damaged. To restore the health of the barricade, a fresh non-damaged plank must be placed after the older planks are taken down. Doors/Windows which are barricaded are protected from damage until the last wooden plank is removed either by the player or by zombie attack.
A metal barricade currently (Version 36.4) is dependent on its HP and will simply break over time. (this is a assumption)
Effects of Barricade
Barricades can delay zombies breaking in by ingame hours, and buys a player time to evacuate or if possible, defend from intruders attempting to break in by leaving via another entrance.
Window Barricade Effects
A barricaded window with 1-2 planks can be viewed through, assuming a curtain/sheet is not down on the window. This allows for some measure of protection while looking out at what is attacking the window. A window with 3-4 planks OR a metal sheet cannot be seen through and there will be no way to see how many zombies are outside or if it is a safe exit to take. A window without a barricade is extremely fragile.
Door Barricade Effects
A barricaded door is unopenable, so think carefully on placement of barricades incase a door is breached that another exit is possible.
Health of Barricade
Each wood plank has 10 hp, e.i. barricade with 4 planks will have 40 hp.
Barricade with metal sheets has 100 hp.
Barricade with metal bars has 100 hp either.
