Choosing the wrong plywood for your subfloor can lead to costly repairs and uneven floors. Don’t let poor material selection ruin your construction project.

The most common types of plywood used for subfloors are CDX, OSB, and Pressure-Treated Plywood. CDX is popular for its strength and affordability, while OSB offers a budget-friendly alternative. Pressure-treated plywood is best for moisture-prone areas.

Understanding the differences between these options will help you make the right choice for your project. Let’s explore each type in detail.

1.What is Plywood?

Ever wondered what makes plywood so strong and versatile? It’s all in its layered construction¹.

Plywood is made by gluing thin layers of wood veneers together, with each layer’s grain perpendicular to the next. This cross-graining² gives plywood its strength and stability, making it ideal for subfloors.

Now, let’s look at why plywood is a top choice for subflooring³.

The Composition of Plywood

Plywood consists of three main parts:

• Face Veneers: The top and bottom layers, usually made from higher-quality wood.
• Core Layers: The inner layers that provide thickness and stability.
• Adhesive: The glue that bonds the layers together, often waterproof for exterior use.

Common Uses of Plywood

Plywood is used in many construction projects, including:

• Subfloors
• Roofing
• Wall sheathing
• Furniture

Its versatility and strength make it a go-to material for builders worldwide.

2.Why Plywood is Commonly Used for Subfloors

A weak subfloor can cause squeaky floors and even structural damage. Plywood solves these problems with its unique properties.

Plywood is durable, affordable, and versatile, making it the best choice for subfloors. It resists warping and provides a stable base for finished flooring.

Here’s why plywood outperforms other materials.

Durability

Plywood’s cross-grained structure distributes weight evenly, preventing cracks and sagging. This makes it ideal for high-traffic areas.

Affordability

Compared to solid wood, plywood is cost-effective without sacrificing strength. It’s a budget-friendly option for large projects.

Versatility

Plywood can be cut to fit any space and works well under various flooring types, including hardwood, tile, and carpet.

3.Types of Plywood Used for Subfloors

Using the wrong plywood can lead to moisture damage or a weak foundation. Let’s compare the best options.

CDX, OSB, and Pressure-Treated Plywood are the most common types for subfloors. CDX is strong and affordable, OSB is cheaper but less moisture-resistant, and Pressure-Treated Plywood is best for wet areas.

Now, let’s break down each type.

CDX Plywood

• Pros: Strong, affordable, good for interior use.
• Cons: Not waterproof, can warp if exposed to moisture.

OSB (Oriented Strand Board)

• Pros: Cheaper than CDX, eco-friendly.
• Cons: Swells when wet, less durable than plywood.

Pressure-Treated Plywood

• Pros: Resists rot and insects, ideal for basements.
• Cons: More expensive, requires special handling.

Comparison Table

Type	Best For	Moisture Resistance	Cost
CDX Plywood	Interior subfloors	Moderate	$$
OSB	Budget projects	Low	$
Pressure-Treated	Wet areas	High	$$$

4.How to Choose the Right Plywood for Your Subfloor Project

Picking the wrong plywood can waste time and money. Follow these steps to make the best choice.

Choose plywood based on climate, budget, and subfloor requirements. For dry areas, CDX works well. For wet locations, use Pressure-Treated Plywood. If budget is tight, consider OSB.

Let’s dive deeper into the selection process.

Climate Considerations

• Dry Climates: CDX is sufficient.
• Humid Climates: Pressure-Treated Plywood prevents mold.
• Temperate Climates: OSB can be used with proper sealing.

Budget Factors

• Low Budget: OSB is the cheapest.
• Mid Budget: CDX offers a balance.
• High Budget: Pressure-Treated Plywood for longevity.

Subfloor Requirements

• Thickness: Use at least 3/4-inch for stability.
• Span Rating: Check the label for maximum joist spacing.
