Regarding compliance with standards, we did some testing in a controlled environment with varying humidity levels. The results were eye-opening. Materials that performed well under dry conditions showed significant degradation in fire resistance when exposed to high humidity. It’s clear that moisture management is crucial for maintaining compliance. Maybe the standards need to be updated to include moisture resistance testing.

I think the key is in the material selection from the get-go. We’ve had success with certain types of cementitious boards that seem to handle moisture better than others. But it’s not just about the material; it’s also about how you install it. We’ve started using a combination of mechanical fasteners and adhesives designed for high-moisture environments. It’s a bit more labor-intensive, but the results speak for themselves.
