What to Consider When Choosing

Confirm compliance with required standards and formaldehyde class for your project
1. Decide whether the construction system is diffusion-open or diffusion-closed
2. Assess expected moisture exposure—product is suitable for humid conditions
3. Check panel thickness and dimensions to match structural needs
4. Evaluate fastener type and edge fastening requirements
