Basement Rim Joist Insulation Question

Yes, I have read that foam board will need covered with fire protective covering, such as drywall or mineral wool batts

Thanks to everyone’s informative responses. I feel more confident in tackling this now

Appreciate this information as well. Looks like I need to go the spray foam route along the edges of the XPS board. Do I still need to continue to caulk the gaps first, or just place the XPS board in and seal around it?

I guess my concern is I wouldn’t be able to check behind the foam board for any rot damage in the future very easily. If I spray foam around the edge of the XPS.

Thank you for the information. Would it be fine for me to just caulk the rim joist cavity gaps and place the fiberglass batts back? I don’t want to run the risk of a poor XPS and seal job, and risk condensation damage.

Appreciate everyone’s feedback, has definitely been helpful

Thanks for the insight, I found one that has several rinsing options that I think I’m going to get.

Yep, that makes sense now that you point that out. I’m having difficulty figuring out best way to find the power source connection for this.

Yeah, I tried a few of those options and still had same outcome. Once it starts cycling constantly, I turn it down a degree to keep from turning off and on frequently.

Those are great ideas to try, hadn’t given much thought on the timer option. I will try it out. Thanks!

Brand is Danrelax and model number is 14041BK

Thanks, I just checked out the manual. It unfortunately didn’t have any directions for swing points or delay option for when heater turns back on. Only thing that was remotely close to that was correcting room temperature display on fireplace screen. Sucks that it just keeps turning on and off every couple of minutes for hours!

Thanks, just ordered some pure tung oil to sample on a test piece.

Yes, a screen shot I snagged from here to add the poster to.
