Is this a mylar alternative?..:S

Hey guys, whilst browsing for mylar i found this reflective sheeting:

An i was wondering if anyone has see/used or even heard of anyone using it..

if so any comments are hugely appreciated..

and also one last thing....Apart from very carefully, how do i go about attaching this sheeting or mylar to the walls of my grow room??

That stuff looks ok, you can attach by using tape and or staples depending on your setup
