How do you remove fiberglass?

Can you please attach a picture. I’m not visualizing this well, as I wouldn’t have put fiberglass near fire, due to the resin.

Thanks

Can you post a picture?

Hi Marie, you should be able to remove the ugly fiberglass with a small rotary tool and clean it up nice so you can put in tile

Hi Marie,

Here's a video that explains how to remove fiberglass from wood. You didn't mention what is underneath but hopefully this will help you. The biggest thing to be aware of is that doing this can be dangerous. Make sure you have all of the safety equipment before you start and please proceed cautiously. If you're not comfortable using this method, do not attempt to DIY. Wishing you the best.

Is a removable cover or a fixed hood?

Try just peeling it off there should be wood under it then add new wood then tile that
