Factors Which Affect Lifespan of Plywood

Plywood is considered to be the best form of wood used for construction of houses and office buildings these days. Considering the many varieties that it is available in and the excellent ways it can be used, there is no wonder that most people want it for their home construction. However, despite the many feature and qualities that it possesses, there are some concerns regarding the structural integrity and lifespan of plywood in the mind of the people. Questions like, how long would the plywood last and when will I have to make repairs or replace the plywood are commonly asked by people when thinking about making use of plywood in their homes.

It is almost impossible to accurately ascertain the lifespan of any wood. However, an estimated guess would be around 10 years or more. However, there is a chance that some of the varieties of plywood might have a much higher life expectancy than that. There are many factors that determine how long the panels of plywood are going to remain in their true form and would not degrade. The following are some of the factors might have an effect on the lifespan of plywood.


The quality of the plywood plays a very important role in determining the lifespan. If you have bought your plywood from a good supplier and you are certain that it is of a good quality then you can expect it to last far more than its guaranteed life expectancy. However, if the plywood is purchased from a discount store it is highly likely that it is not going to last long. Such plywood usually has a lumpy surface and sheet voids present in it which are hallmarks of its inferior quality. Thus, when buying plywood for any kind of construction purposes make sure to buy them from a hardwood supply or cabinet supply outlet.


Moisture is one of the biggest factors that can affect the endurance of plywood. If the plywood is regularly exposed to high levels of moisture then there is no way for it to sustain its quality for a long period of time. This is the reason why plywood used in houses that are located in humid areas does not last that long and degrades much more quickly. Thus, if you want to preserve the plywood lifespan then it is extremely necessary that you keep it safe from being exposed to moisture or buy plywood with high level of water repellency.

Chemicals and Treatment Process Used

Plywood is an engineered wood which is made after passing wood and other chemicals through certain treatment procedures. The chemicals and the treatment process used for making a particular type of plywood determine the qualities and features it would have and consequently its life span. For instance, pressure treated plywood has a life expectancy of about 20 years while MRF and OSB have an expected life of around under 30 and up to 60 years. The marine grade plywood even has a life-time guarantee in the United States.
These are only a few of the factors that affect the life expectancy of plywood. There are a number of other factors that might play a role in determining the lifespan of plywood used in your home. However, if you take care of it and protect it from moisture abuse then there is a chance that it might last longer than its expected lifespan.
