A material which exists in the form of a sheet and synthesized from wooden veneer packed together is referred to as plywood. Plywood is a type of engineered wood that makes composite material by binding resin and wood fibers. There are various applications of plywood based on their manufacturing. Although both interior and exterior plywood, are used nowadays, there lies a subtle difference between the two. Exterior plywood is generally made of fir. The lumber is known to be harvested in the North-West and it is highly in demand because of its durability and availability.
Difference between interior and exterior plywood
The factor which sets interior and exterior plywood apart is the glue. A waterproof resin-based glue is used during the production of exterior plywood. The glue on drying becomes solid and crystalline that does not produce any type of moisture. Thus it is coated on the layers of the plywood to prevent damp. Since exterior plywoodis more susceptible to damping and fading than interior plywood as the former remains exposed direct sunlight and rainfall, superior quality of waterproof paint or any other finish can be coated on to the plywood to prevent these adversities.
Recognizing exterior plywood
As there are different types of plywood available for different purposes, you need to identify the one used solely for external use. The easiest way to identify them is to read the marks labeled on the plywood which exists as a three-lettered label. Generally, in case of exterior plywood, one can find the label “CDX”. The letters of the alphabet signify the strength of the plywood, for example “A” denotes the topmost ranking, “B” the second best and so on. “CDX” denotes the particular plywood has one side named as “C” and the other named as “D”. The letter “X” denotes that the particular plywood is meant to be used in the exterior of the house and not on the interior.
Applications of exterior plywood
Even though the name suggests, exterior plywood is not just limited to the exterior of a building, on the contrary it has varied applications. Some of its applications are discussed below:
- In many buildings, exterior plywood is used on the floors as well. It is due to the fact that it is moisture-resistance so it prevents unnecessary damp on the floors.
- Exterior plywood is also seen in construction of kitchen cabinets or modular kitchen. It is used on the sinks and countertops of kitchen as well.
- Apart from its used in the exterior of a building it is widely used in the interiors of the buildings as well.
Disadvantages of exterior plywood
- Exterior plywood can turn out to be more expensive that using paints or other coatings.
- It consists of patches in its surface which makes it appear defective.
Thus, exterior plywood can be used anywhere depending on your need and taste. Starting from exterior sheathing to the interior of the house such as floors, walls, and other spaces, its application is seen everywhere around. Exterior plywood not only gives a different and unique look to the house but also keeps the house free from damps, strong sunlight and other adverse weather conditions. It is also possible to make various designs on the plywood to present them in a whole new look altogether. Plywood being a good insulator of heat, also keeps the interior of the home considerably cooler in the hot, summer months and warmer in the winter months when the outside is designed with exterior plywood. For all these advantages, using exterior plywood has become quite popular nowadays.
