The reason why HDHMR is termite-proof is that small wood content is removed with the pressing technique. While this improves the board or sheet's density, it also eliminates any unusable particles that can attract termites. Termites are highly destructive pests that can infest and damage various types of wood, including engineered wood products like HDMR plywood. While HDMR plywood might offer some level of resistance to termites due to its manufacturing process and composition, it's not a guaranteed termite-proof material. If you're concerned about termite infestation, it's important to take appropriate precautions regardless of the type of wood you're using. This might include applying termite-resistant treatments, using physical barriers like metal screens, or implementing proper construction techniques to minimize the risk of termite infiltration. It's always a good idea to consult with pest control professionals or experts in your area to get the most accurate and up-to-date information on termite prevention strategies and the suitability of specific materials for your project.
