Roxul Monoboard Plus in BUR

Hello all! It's been awhile since I've participated in this forum. I've spent the last couple of years working in my business rather on the business.

I have a question for those out there, if any, that work with asphalt roof systems and have experience using Roxul Monoboard as a cover board in a BUR assembly. Have you had any problems with it? Any issues with the coating on top of the compressed board? We love it for torch applied systems, but have recently seen some major issues when mopping hot asphalt to it with fiberglass felts.

All questions & comments are welcome.

Thanks Colpaw
