What Materials Are Used for Emergency Property Board-Up?
Last updated October 31, 2026
The short answer
Plywood Panels
The main material for a board-up is plywood. Thick sheets, usually 5/8-inch or 3/4-inch, provide strength to resist wind, debris, and unauthorized entry. The pros cut each panel to fit the exact opening, leaving a small gap for expansion in hot weather.
Exterior-grade plywood, often called CDX, resists moisture better than interior types. In dry climates, the boards may stay in place for weeks, so durability matters. The pros may seal the edges with caulk to keep water out.
- 5/8-inch or 3/4-inch exterior plywood
- Cut to fit each window or door opening
- Small gaps for expansion and contraction
- Edges sealed with caulk to block moisture
Framing Lumber
To hold the plywood securely, pros use 2x4 or 2x6 lumber as framing. These boards create a sturdy frame around the opening, giving the plywood a solid surface to attach to. The frame also helps distribute pressure from wind or impacts.
Framing lumber is often treated or primed to resist rot, especially if it will be exposed to rain. In wet conditions, the pros might use pressure-treated wood for the frame. This adds a layer of protection against moisture damage while the board-up is in place.
- 2x4 or 2x6 studs for framing
- Treated or primed to resist rot
- Screws or nails to attach frame to structure
- Adds stability for the plywood panels
Fasteners and Hardware
Screws and nails are the workhorses of a board-up. Pros choose corrosion-resistant screws, like galvanized or stainless steel, to prevent rusting. They may use lag bolts for extra security on doors or large windows, and wood screws for standard frames.
The pros might also use metal brackets or hurricane clips to reinforce the attachment points. These add strength without needing extra thick plywood. For a temporary fix, the goal is to make the board hard to remove from the outside while still allowing easy removal later.
- Galvanized or stainless steel screws
- Lag bolts for high-security areas
- Metal brackets or clips for reinforcement
- Easy removal later with a drill
Weatherproofing Materials
A board-up must keep out rain and wind, not just intruders. Heavy-duty plastic sheeting, often 6-mil poly, can be stapled over the plywood to create a water-resistant barrier. The pros may also use tarps or building wrap for extra protection.
Caulk or expanding foam seals gaps around the edges of the boards. This stops water from seeping in and prevents drafts. In wet winter conditions, this weatherproofing is essential to avoid further water damage inside your home.
- 6-mil poly sheeting or tarps
- Caulk or expanding foam for gaps
- Seals against rain and wind
- Protects interior from moisture
Tools and Safety Equipment
The pros use standard tools: circular saws to cut plywood, drills for screws, hammers for nails, and levels to keep everything straight. They also bring ladders and scaffolding to reach upper windows. Safety gear includes gloves, safety glasses, and dust masks.
On a job, the pros may need to remove broken glass or debris first. They use heavy-duty gloves and a pry bar to clear the opening. This ensures the board-up fits flush and that no sharp edges remain to cause injury.
- Circular saw and drill
- Ladders and scaffolding
- Gloves, glasses, and dust masks
- Pry bar for debris removal

How long does a board-up stay in place?
A board-up can stay for days to weeks, depending on the extent of damage and weather. In a dry climate, it might last longer. The pros will advise when permanent repairs can begin. Policies vary, and your insurer decides what is covered.
Can I board up my own windows?
You can attempt it, but proper board-up requires precise cutting and secure fastening. A poorly installed board can fail in wind or be easy to pry off. The pros have the tools and experience to do it safely. Consider the risk of further damage.
What if the opening is an odd shape?
For unusual openings, the pros create custom-cut plywood panels. They may use multiple pieces or build a frame to fit. They also use plastic sheeting to cover irregular areas. This ensures a snug fit that keeps weather and intruders out.
