Factors that affect the lifespan of plywood
Plywood is a versatile building material used for a wide range of construction projects, from flooring and roofing to walls and furniture. However, like any other material, plywood has a lifespan that largely depends on various factors. Some of these factors include:
- Quality of the plywood: The quality of the plywood is one of the most significant factors that determine its lifespan. High-quality plywood is manufactured using high-grade wood veneers, which are bound together using strong adhesive. This makes it more durable and long-lasting compared to low-quality plywood that is often made using less sturdy wood and weak adhesive.
- Climate and exposure to sunlight: Climate and sunlight exposure are also critical factors that affect the lifespan of plywood. When exposed to extreme weather conditions such as rain, heat, and cold, plywood tends to swell, shrink, and eventually rot. The same happens when plywood is exposed to direct sunlight for prolonged periods, causing it to become brittle and lose its strength.
- Treatment and maintenance: Proper treatment and maintenance of plywood can also significantly affect its lifespan. Treating plywood with preservatives can make it resistant to rot, decay, and insect infestation, thus prolonging its lifespan. Additionally, routine maintenance practices such as cleaning, sanding, and recoating can help protect the plywood from wear and tear, thus increasing its durability.
- Application: The application of plywood also plays a critical role in determining its lifespan. Plywood used for structural purposes such as roofing and flooring should be stronger and more durable compared to that used for non-structural applications like paneling and cabinets.

When it comes to the longevity of plywood, moisture is one of the most important factors to consider. Plywood that is exposed to moisture can quickly deteriorate and lose its strength and durability. Let’s take a closer look at how moisture affects the lifespan of plywood.
- Rot and decay: Plywood that is exposed to moisture, especially over an extended period, can become susceptible to rot and decay. The wood fibers in the plywood absorb water, leading to the growth of fungi, mold, and other microorganisms that break down the wood fiber structure, leaving it weak and brittle.
- Warping: Moisture can cause plywood to warp or bend. As the wood absorbs moisture from the air or surroundings, it expands and can alter shape. Over time, this can affect the structural integrity of the plywood, making it less stable.
- Delamination: Plywood comprises multiple layers of wood veneer that are bonded together using glue. When exposed to moisture, the glue can degrade, causing layers of the plywood to separate from one another. This process is referred to as delamination and weakens the structure of the plywood.
To mitigate the impact of moisture on plywood, you should opt for high-quality plywood that has been treated with preservatives. You should also store and use plywood in a dry, well-ventilated area, particularly when it is not in use.
It is worth noting that even high-quality and well-preserved plywood won’t last indefinitely. Table 1 below summarizes the lifespan of three common types of plywood:
|Type of Plywood||Average Lifespan|
|Interior grade||10-15 years|
|Marine grade||30-50 years|
