What Materials Are Used for Professional Board-Up?

The main material for board-up is plywood. Pros often use 5/8-inch or 3/4-inch thick plywood because it resists bending and holds up against wind and impact. Thinner sheets can warp or crack, leaving the opening vulnerable. The grade matters too; exterior-grade plywood handles moisture better than interior grades.

For larger openings like sliding glass doors, thicker plywood or additional bracing may be needed. The size of the opening and the condition of the surrounding frame influence what the pros select. In some cases, they use oriented strand board (OSB) as a cost-effective alternative, though it may not be as strong as plywood.

• 5/8-inch or 3/4-inch exterior plywood
• Oriented strand board for budget-friendly options
• Galvanized screws that resist rust
• Heavy-duty nails for temporary fastening
• Metal brackets for extra support on wide openings

Sometimes the existing frame is damaged, so the pros add temporary framing. They use 2x4 lumber to create a sturdy structure around the opening. This provides a solid surface to attach the plywood and distributes the force across a wider area.

Metal brackets and angle braces can reinforce the corners and edges. These are especially useful for large openings or areas with high wind exposure. The goal is to make the barrier as secure as the original structure, even if only temporarily.

For security, the pros may use screws with special heads that are hard to remove without the right tool. They can also install metal bars or brackets that lock the plywood in place. These measures deter unauthorized entry while the property is vacant.

The pros also consider fire safety. They avoid materials that easily ignite and ensure that the board-up does not block fire escapes or access for emergency services. This balance between security and safety is a key part of professional board-up work.
