1/2 in. Plywood: Types, Uses, and Benefits
Plywood is commonly used in structural applications as it can withstand weather exposure and stress. It is also used in bins, crates, outdoor furniture, internal structures and boxes. Plywood is diverse in thickness, but the most popular is ½ inch plywood. In this article, we will learn about 1/2 plywood, its various types, and common uses in construction and DIY projects. And also discover the benefits of using this versatile and durable material for your next project.

Does plywood come in half inch?

There are numerous options for plywood thickness, which can influence your project. Plywood thickness ranges from 1/8 inch to 1 ¼ inches. However, keep in mind that these measurements do not reflect the actual thickness of the plywood.

During the manufacturing process, sanding the wood can remove up to 1/32 inch of material from the plywood sheet. Therefore, a plywood sheet listed as 3/8 inch thick actually measures 11/32 inch in thickness.

The standard plywood thicknesses are 1 ¼, 1 1/8, ¾, 5/8, ½, 3/8, ¼, and 1/8 inches. However, due to sanding, the actual thicknesses are 1 ¼, 1 1/8, 23/32, 19/32, 15/32, 11/32, 1/4, and ⅛ inches, respectively. These measurements account for the material removed during the sanding process.

How thick is 1/2 inch plywood?

Because the actual thickness may vary, measuring the plywood sheet using a caliper is the only accurate way to determine its thickness. A ½ sheet is actually 15/32 thick.

How much weight can a 1/2 sheet of plywood hold?

Looks are deceiving in this case, because plywood is a lot stronger than it seems. Plywood is actually engineered to support weight and provide strength. 1/2-inch plywood can hold up to 35 pounds per square foot.

Is 15/32 the same as half inch?

After the plywood is manufactured, it will shrink as it dries making it thinner than originally cut. Also, the top layer is sanded after the plywood sheet is made. The sanding process will take a small amount of the thickness away as well. So ½ inch plywood is the same as 15/32 inch plywood.

How many sheets of 1/2 plywood are in a bundle?

There are several factors that can affect the number of plywood sheets in a bundle. One of the main factors is the thickness of the plywood. Thicker plywood sheets take up more space and therefore fewer sheets can fit in a bundle. Thinner plywood sheets, on the other hand, can be stacked more closely together, allowing for more sheets in a bundle.

There are roughly 48 sheets in a lift of 1/2″, depending on manufacture can be as much as 52, and one supplier does units of 75. A sheet of 4×8 1/2″ is about 50 pounds, so a lift/unit would weigh roughly 2400lbs. But 60 sheets is a common quantity for this thickness.

Is 1/2-inch plywood good for subfloor?

Using 1/2-inch plywood for subflooring is generally not recommended for most residential flooring applications. Subfloors are a crucial part of a building’s structure, providing a stable base for the finished flooring. Here are some considerations:

Subfloor in your home

Thickness and Structural Integrity

  • Standard Thickness: The typical recommended thickness for subfloor plywood is 3/4 inch (or thicker) because it provides the necessary strength and rigidity to support the weight and movement of people and furniture.
  • Flexibility: 1/2-inch plywood may be too flexible, leading to squeaks, deflection, and potentially compromising the integrity of the flooring above, especially under heavy loads or high-traffic areas.

Building Codes and Recommendations

  • Building Codes: Many building codes and standards require a minimum subfloor thickness of 3/4 inch for plywood when used over joists spaced 16 inches apart. If the joist spacing is wider, thicker plywood might be required.
  • Overlay and Underlayment: If 1/2-inch plywood is to be used, it often needs to be installed over an existing subfloor or used as an underlayment over a thicker subfloor to meet the structural requirements.

Application-Specific Considerations

  • Joist Spacing: In situations where the joists are closer together (e.g., 12 inches apart), 1/2-inch plywood might be more acceptable, but it’s still not ideal compared to 3/4-inch.
  • Flooring Type: For certain types of flooring that are more forgiving of minor flexing (such as carpet), 1/2-inch plywood might be used as part of a multi-layer system.

Recommendations for Best Practices

  • Optimal Thickness: Use 3/4-inch plywood or oriented strand board (OSB) for most subfloor applications. Thicker subfloors provide better support and longevity.
  • Additional Layers: If using thinner plywood, ensure it is part of a composite system where additional layers or materials compensate for the lack of thickness.

In summary, while 1/2-inch plywood might be used in specific situations with additional reinforcement or in multi-layer applications, it is generally better to opt for 3/4-inch plywood to ensure a sturdy, long-lasting subfloor.

The specifics of your project will determine the size and type of plywood you need. For instance, if you’re constructing a doghouse or covering subfloors, softwood plywood made from cedar, redwood, or pine is ideal and is available in sizes ranging from 4 x 8 feet to 5 x 5 feet.

For projects like making cabinets or building a closet, lumber core plywood is a good choice, typically in 18 mm thick panels. This type of plywood consists of three layers, with hardwood on the outer layers and basswood on the inner layer.
