I built mine out of this stuff and before I sealed the cracks with aluminum tape any light leak was like a laser beam with a 600w mh in a 4'x4'x8' box. Mylar is only an added expence that is not needed IMAO.
I took my light meter to Home Depot about a month ago, and checked those very panels you speak of :thumbsup: they reflected better than anything else I could find in the store ... I would buy them , but am going with an oak finish paneling, (painted white on reverse side), purely for cosmetics ... :smokin:
