ISO Intello Plus scrap piece!

Good morning all,
I am working on a tiny house build and have run out of my interior air sealing membrane, a product called Intello Plus made by Proclima.  In lieu of buying an entire additional roll (65 feet @$170), I thought I'd check to see if anyone has any scrap they'd be willing to part with. I only need a 14' long piece (5' width). Thanks in advance!
