Drywall and plywood are two of the most recommended wall materials, each offering unique benefits for construction projects.
While plywood provides strength and versatility, drywall is the preferred choice for seamless, polished interiors. But why is drywall so commonly chosen over plywood? Knowing their differences helps make better project decisions.
At BRK Drywall, we guide homeowners and contractors across the USA in selecting materials and achieving flawless installations. This guide explores the pros and cons of drywall and plywood, helping you choose the best option for your space.
Composition and Characteristics – Drywall vs Plywood
What is Drywall?
Drywall, also known as gypsum board, consists of a gypsum core sandwiched between two durable paper layers. This lightweight, versatile material is a staple in interior construction, used to create smooth, even walls and ceilings.
Its composition makes it easy to cut drywall, install, and finish, making it the go-to choice for both residential and commercial projects.
What is Plywood?
Plywood is a strong, engineered wood product made by bonding multiple layers of thin wood veneers together, with the grain of each layer running perpendicular to the one below. This cross-laminated structure enhances its strength, stability, and resistance to warping.
Commonly used in construction for subfloors, walls, and roofing, plywood is also a popular choice for crafting furniture and cabinetry due to its durability and versatility.
Plywood vs Drywall Cost Comparison
Material Costs
When it comes to the two material costs, drywall is the more budget-friendly option, averaging around $10 per sheet. In contrast, plywood is significantly more expensive, typically ranging from $35 to $50 per sheet, depending on the grade and thickness.
This cost difference makes drywall a preferred choice for large-scale projects, where affordability and efficiency are key considerations.
Installation Costs
Drywall installation is typically faster and more straightforward, involving simple steps like measuring, cutting, taping, and finishing. In contrast, plywood installation demands more time and effort, especially when a smooth, paintable surface is required.
Additional tasks such as sanding or skim-coating add to the labor, making plywood installation more labor-intensive and costly overall.
Maintenance Costs
When it comes to long-term maintenance, damaged drywall is generally more affordable to repair, with straightforward patching methods for dents and holes.
Plywood, while more durable against impact, can be costlier to fix if damaged, as repairs often require replacing entire sections. Over time, drywall’s lower maintenance costs make it a more economical option for most projects.
Material Properties
Strength, Weight, and Flexibility
Both drywall and plywood have distinct material properties that influence their performance and suitability for projects. Understanding their strength, weight, and flexibility helps in making the right choice.
- Strength and Durability: Plywood is stronger and more durable, ideal for areas exposed to impact or heavy loads.
- Weight Considerations: Drywall is lighter and easier to handle, streamlining the installation process compared to heavier plywood.
- Flexibility: Plywood’s flexibility suits curved or non-standard applications, while drywall’s rigidity is ideal for flat, seamless surfaces.
Installation Process
Drywall Installation
Installing drywall involves measuring, cutting, securing panels to studs, and finishing seams with taping, mudding, and sanding. It requires basic tools like a utility knife, drywall screws, and joint compound, making it relatively straightforward for most projects.
Plywood Installation
Plywood installation includes measuring, cutting, and securing panels with nails or screws. Additional steps may involve sanding for a smooth finish. Tools like a circular saw and drill are essential, with installation requiring more effort compared to drywall.
Durability and Maintenance
Durability of Drywall
Drywall is susceptible to dents, scratches, and moisture damage, particularly in high-traffic or damp areas. However, it is easy to repair with straightforward patching techniques, making maintenance manageable.
Durability of Plywood
Plywood is highly resistant to impact and wear, making it a durable option for demanding environments. However, exposure to moisture can lead to warping or delamination unless properly sealed, requiring preventive measures for long-term durability.
Fire Resistance
Drywall’s gypsum core gives it excellent fire-resistant properties, slowing the spread of flames and making it a safer option for meeting fire code requirements. In contrast, plywood is highly combustible, posing greater fire risks, especially in shared garage walls or other areas requiring enhanced fire safety.
Insulation and Soundproofing – R-value Drywall vs Plywood
Thermal Insulation (R-Value) Comparison
Drywall has a lower R-value, providing minimal thermal insulation on its own. Plywood walls offer slightly better insulation due to their wood composition, but neither material excels without additional insulation layers.
Plywood vs Drywall Soundproofing Capabilities
Drywall is more effective at reducing noise transmission, making it the preferred choice for soundproofing interior walls. Plywood, while durable, performs less effectively in minimizing sound.
Aesthetic and Finishing Options – Drywall vs Plywood Walls
Finishing Drywall
Drywall offers versatile finishing options, including painting, texturing, and wallpapering, making it ideal for creating polished, seamless interiors. Its smooth surface is easy to prepare, ensuring a flawless finish with minimal effort.
Finishing Plywood
Plywood can be stained or varnished to showcase its natural wood grain, adding warmth and character to a space. However, achieving a smooth painted finish can be challenging due to visible grain, often requiring additional steps like sanding or skim-coating.
Application in Specific Areas – Plywood Walls vs Drywall
Choosing between drywall and plywood often depends on the specific area of application. Factors such as durability, moisture resistance, and environmental conditions significantly determine the best material for the job.
- Drywall in Garages: Ideal for creating a clean, fire-resistant surface in garage spaces. However, it’s less durable against impact.
- Plywood in Garages: Offers superior durability and the ability to hold heavy fixtures but is more expensive and less fire-resistant.
- Drywall in Moisture-Prone Areas: Suitable for kitchens and bathrooms with proper moisture-resistant treatments, though it can still be vulnerable to prolonged exposure.
- Plywood in Moisture-Prone Areas: More resistant to water damage but may require additional sealing to prevent warping.
- Other Applications: Drywall is best for flat, seamless ceilings and interior walls, while plywood excels in exterior walls or areas needing extra strength and flexibility.
Environmental Impact
Drywall and plywood have distinct environmental impacts. Drywall often includes recycled materials but has energy-intensive production. Plywood, made from renewable wood, is durable and reduces replacements.
However, widespread plywood use could strain timber supplies, highlighting the importance of sustainable sourcing.
Frequently Asked Questions
Can Plywood Be Used Instead of Drywall for Interior Walls?
Yes, plywood can be used for interior walls, offering greater strength and the ability to hold heavy objects without additional support. However, it is more expensive and less fire-resistant than drywall.
How Does the Fire Resistance of Drywall Compare to Plywood?
Drywall is more fire-resistant than plywood due to its gypsum core, which slows the spread of flames. Plywood, being composed of wood, is more combustible and poses a higher fire risk.
Is Drywall or Plywood Better for Soundproofing?
Drywall generally offers better soundproofing capabilities than plywood, making it a preferred choice for interior walls where noise reduction is desired.
Which Material Is More Cost-Effective for Wall Construction?
Drywall is typically more cost-effective than plywood, both in terms of material and installation costs, contributing to its widespread use in residential and commercial construction.
