TISI plywood are plywood that has been through the production and testing process according to Thailand industrial standards TIS 178-2549 by the Thai Industrial Standards Institute (TISI), Ministry of Industry in terms of properties such as width (mm), length (mm), thickness (mm), moisture, strength, glue adhesion, etc.
TISI plywood is divided into 4 catagories according to the glue used in production as follow:
- Exterior plywood – Use an adhesive that is resistant to weather, cold water, boiling water, steam and dry heat. This type of plywoods are suitable for outdoor use or when the woods are exposed to water or high moisture.
- Moisture resistant plywood – Uses an adhesive that is resistant to weather, cold water, boiling water, and steam for a limited time. This plywood are suitable for indoor and outdoor use or when plywoods are occasionally exposed to water or high moisture content.
- Interior plywood – use a mildly water resistant glue. This plywood is durable in hot water For a limited time, but cannot tolerate boiling water. They are suitable for indoor use or in location that are not exposed to water or high moisture.
- Temporary use plywood – use cold water resistant glue for a limited time. Suitable for temporary use. Example of this type of plywood include plywoods used in construction site.
In addition, each type of TISI plywood is also divided into 4 quality layers according to the characteristics of the face and back veneer used. For example, 2/4 grade means the face veneer is grade 2 and back veneer is grade 4.
Grade 1 is the most beautiful face and free from defect is suitable for work that need to showcase the actual wood surface while Grade 4 allows for more natural defects such as knots and wood discoloration.
