Ok I am finding duct tape is not holding my mylar to the black plastic. It just gets warm and peels off anyone have a good alternative tape or idea??

Yeah thats why they don't even use duct tape for duct work. Find the aluminum tape at home center - it sticks to anything. It has a shiny metal side and then an adhesive side that is then backed with wax paper. I find it works well.

maybe you can put tape over where u want to put the tac in, to reinforce the hole.

you need "gorilla tape". it's black duct tape. home depot, napa auto parts,....

it peels off easy at first but once it warms up, or whatever it does, it holds. i have a 3 x 6 x 6 room held together with gorilla tape. over a year old and still holding.

now if i could get the cat to stop sharpening her claws on the plastic i'll be good.

I am liking the velcro idea if it sticks to plastic. My room is framed and built with 6 mil plastic so have 4 8 foot pieces to hold up..hmmm no tacks would work so its metal tape, gorilla tape or velcro now hmmm

i use a simple stapler to staple velcro to black plastic. roll the edgs of plastic to make it a couple layers thick. my whole door to my room is a velcro zipper stapled to plastic.
