In a previous Blog I discussed the change to the Building Codes that requires manufactured wood floor framing to be covered with a 30 minute radiant barrier because they will burn quicker in a fire. This means covering up those unfinished basement ceilings as a safety precaution. And as I stated earlier, I strongly recommend that builders be aware of the codes and requirements around this.
However, there are new ways to protect exposed TJI floor framing for fire reasons. Instead of installing an entire ceiling, you can also install boards along the exposed sides of the web. I have seen this done and while I haven’t done the calculations, this would probably use less material and be more cost efficient than installing the entire ceiling.
I have been following this topic and I urge you to research and make sure you are aware of the options available.
If anyone has found other solutions, please let me know so we can share them with others.
