When building stairs, the choice of material for the risers is a crucial decision. Two common options are 2x8 lumber and plywood. This video explores the pros and cons of each material and offers insights to help you make an informed choice.
2x8 Lumber
2x8 lumber is a popular choice for stair risers due to its strength and availability. It is readily available at most lumberyards and can be easily cut and installed. However, 2x8 lumber has some drawbacks.
Movement: Lumber is prone to movement due to changes in moisture content. This can lead to gaps between the risers and treads, causing squeaking and compromising the structural integrity of the stairway.
Cupping and warping: Lumber can cup or warp over time, especially if it is not properly dried or installed. This can affect the appearance of the stairway and create safety hazards.
Plywood
Plywood is an engineered wood product composed of multiple layers glued together. It is known for its stability and resistance to warping. Plywood stair risers offer several advantages:
Stability: Plywood is less prone to movement than lumber, making it a more stable option for stair risers.
Dimensional stability: Plywood is less likely to shrink or swell due to moisture changes, reducing the risk of gaps between the risers and treads.
Strength: Plywood is strong and durable, providing adequate support for stair treads.
Hybrid Approach
The video suggests a hybrid approach that combines the best of both worlds. You can use plywood for the risers and 2x8 lumber for the treads. This approach leverages the stability of plywood for the risers while utilizing the strength and availability of lumber for the treads.
Additional Considerations
Adhesives: When using either 2x8 lumber or plywood, it is crucial to use high-quality construction adhesive to secure the risers to the treads and stringers.
Fasteners: Use appropriate fasteners, such as screws, to reinforce the connection between the risers, treads, and stringers.
Building codes: Always comply with local building codes regarding stair dimensions, materials, and construction methods. Conclusion
The choice between 2x8 lumber and plywood for stair risers ultimately depends on your preferences, budget, and desired level of stability. Plywood generally offers superior stability and dimensional stability, making it a preferred choice for many stair builders. However, if you prefer to use 2x8 lumber, consider the hybrid approach or take steps to minimize its movement and warping. By carefully weighing the pros and cons of each material and following best practices, you can build a safe and durable stairway that will enhance the value and functionality of your space.Should You Use 2x8 or Plywood Stair Risers?
