How To Board Up Windows In Project Zomboid

Boarding up windows in Project Zomboid is an essential survival mechanic that provides security from wandering hordes, blocks line-of-sight to deter detection, and dampens interior sound emissions. Mastering the placement of planks, metal sheets, and security bars ensures your safehouse remains structurally secure against zombie breaches.

Pre-Operation and Equipment Checklist

Securing a permanent or temporary safehouse requires advance planning, proper tooling, and an understanding of material physics in Project Zomboid. Without the correct inventory items equipped, your character will be vulnerable to sudden ambushes while fumbling through container menus.

• Essential Gear, Tools, and Materials:
  
  
  • A Hammer (or Club Hammer) kept in your primary inventory or main backpack.
  • Planks (obtained by sawing logs with a Wood Axe or dismantling furniture with a hammer and saw).
  • Nails (stored in boxes requiring an unboxing action, yielding roughly 100 nails per box).
  • Optional upgrades: Metal sheets, metal bars, blowtorches, and welding masks for advanced barricades.
• Mandatory Prerequisite Knowledge and Standards:
  
  
  • Understanding the distinction between single-sided barricades (interior versus exterior placement) and double-sided protection.
  • Carpenter skill level benchmarks (Level 2 unlocks wooden sheet barricades; Level 4 unlocks double-sheet barricades).
• Estimated Benchmarks:
  
  
  • Securing an average residential house takes approximately 10 to 15 minutes of in-game time per room, consuming 2 to 4 planks per standard window.

Step-by-Step Window Barricading Procedure

Step 1: Gather and Organize Your Fastening Materials

Before approaching any window, ensure your hammer is moved to your main inventory and you have at least two planks and four nails per window pane. If your nails are currently inside a cardboard box, right-click the box in your inventory and select "Open" to make the individual nails accessible to your crafting queue.

Warning: Never attempt to board up windows while carrying heavy, non-essential loot, as your character's movement speed and attack speed will be drastically penalized if over-encumbered by the weight of unneeded items.

Step 2: Position Your Character on the Correct Side

Approach the window you intend to fortify and determine whether you want the barricade on the inside or the outside. Placing planks on the outside is standard practice to prevent zombies from breaking the glass directly, but interior barricades allow you to open and close windows or hang bedsheets for privacy without destroying your wooden fortifications. Right-click the window or use the carpentry menu (accessed by pressing B or using the context menu) to initiate the placement.

Pro-Tip: Always prioritize exterior barricades on ground-floor windows to absorb structural damage before the zombie horde manages to shatter the fragile window glass.

Step 3: Install Planks and Scale Up Your Defenses

Select the "Barricade" option from the context menu to attach up to four planks per window side. Your character will hammer each plank sequentially, with the duration of the task influenced by your character's traits and overall fatigue level. Once basic planks are exhausted, higher carpentry levels allow you to upgrade standard plank configurations into solid wooden sheets that completely eliminate visibility into the structure.

Step 4: Implement Metal Reinforcements for Ultimate Security

Once you reach high levels in both Carpentry and Metalwork, dismantle scrap metal or utilize propane torches and welding masks to weld metal sheets or metal bars over your windows. Metal bars provide a major tactical advantage because they block physical passage for zombies while maintaining your line-of-sight to the outside world, letting you monitor exterior threats from safety.

Material Durability and Visibility Comparison

Common Site Failures and Field Fixes

• Root Cause: Character is constantly interrupting the barricading action or failing to equip the hammer.
  
  
  • Actionable Fix: Ensure the hammer is placed directly in your main inventory rather than a secondary container or floor tile, and verify your character is not panicked or exhausted.
• Root Cause: Zombies are bypassing the exterior barricades and attacking the interior space immediately.
  
  
  • Actionable Fix: You accidentally placed the planks on the interior side while the zombies attacked the outside glass; dismantle the interior boards and reconstruct them on the exterior frame.
• Root Cause: Total inability to attach wooden sheets despite having sufficient planks and nails.
  
  
  • Actionable Fix: Your character's Carpentry skill level is too low; read intermediate carpentry books and saw redundant furniture to grind out the required skill level thresholds.

Frequently Asked Questions

Can I still see through windows after boarding them up?

Standard planks and wooden sheets completely block line-of-sight for both you and the zombies, preventing anyone from seeing through the glass. However, metal bars allow you to look outside while simultaneously blocking physical entry.

Is it better to board windows from the inside or outside?

Exterior barricades are superior for damage absorption because zombies must destroy the wooden planks before they can shatter the glass window pane. Interior barricades are typically reserved for upper floors or situations where you need to keep windows functional for ventilation.

How many planks can you put on a single window?

You can install up to four planks on the exterior side and an additional four planks on the interior side of a single standard window frame, totaling eight structural layers of reinforcement.

Do zombies attack barricaded windows even if they cannot see inside?

Yes, zombies possess environmental tracking capabilities and will attack barricaded safehouses if they heard a noise inside, smelled a player, or migrated directly into the structural walls during a roaming phase.
