I need a flexible gasket for my upcoming mini split install. Roflex comes in such a small piece that I’d need two of them, one inside and one outside. That’d be about a hundred bucks with shipping. Meanwhile, I see EPDM rubber sheeting of the same thickness on eBay for less than half that for ten times the material. Is there something special about Roflex, or will the generic sheeting do the same job?
