How to attach Panda Film to Foam Board Insulation?

A 2x2 across the top, wedged in to the corners with the film attached to it via staples, pressed to the wall (stapled film side to wall) and pulled tight, couple short staples down the wall to stop the flapping. 2x2 wedged at the bottom too. Easily removable with minimal damage... that’s all I got... and I’m high.

Tyvek tape is what I used on one of my rooms. It seems to be holding very well, and it can be removed from most surfaces relatively easily when you want to take it off.

I used backer nails to fasten my reflective material to foam board. Then went over with reflective duct tape.
Tried searching for backer nails and couldn't find anything. Anyways I did a tape test against the panda film (the black back side has some texture to it so tape sticks really easy) and the gorilla tape ripped the panda and foam board before coming off which is what I want I guess.

One interesting thought I had due to the 2x2 response above is using plastic or metal poles to wrap the panda film around instead. Could be shower poles or the poles they actually make for use with vapor barriers. Just not sure about negative pressure and cleaning it.

Sorry, I guess they are called cap nails.

If you already have vapor barrier why use the panda film at all? For reflection? You could just paint your foam board flat white and call it a day no?

at the hardware store they sell screws that have a plastic washer attached to them you can use those for attaching your foam board to the studs. since its just a shed i agree with some of the other people get some cheap plywood and screw through the plywood and the foam board behind it directly into your studs paint it white and call it day. messing around with all that plastic may be a hassle if it happens to detach from the ceiling and happens to land on one of your light fixtures that may be bad news.

Interesting thought... do you think it would stick to this and be effective? The panda film is mainly for reflection yes but also to protect the foam board from moisture and the other vapor barrier was to protect the fiberglass as fiberglass has issues with mold. A little overboard? Probably. Effective? Definitely :)

Are you exhausting this shed or using an AC. If your exhausting the shed there will be negative pressure and therefore needs to hold better. I have used Ferring strips, painted white, in several rooms to hold up the panda film when negative pressure is present with no issue.

if you don’t have exhaust fans I guess tape might work, but I’d be afraid of it falling down mid run, not all places are easy to get to and fix while plants are in a room. Also you don’t want the plastic to potentially pull lose and land on either something hot (grow light) or on your plants.

If your going with tape I found a window flashing similar to zap flashing tape but foil backed. You use a heat gun then rub something hard over it and it will adhere and never come loose. Your foam board would prob come with it if you needed to remove it.

Good questions... for now sine the room is sealed and it is winter out we only want to exhaust as needed to keep it around 85-90 degrees in the room so the added CO2 actually is useful. After winter is over we will go the AC route.

I am seriously considering the ferring strips idea... as you mentioned painting them white I take it you "pinch" the panda in place?
My concern with the tape idea is simply that... if I ever need to take it down don't need the entire room being destroyed ya know.

3m makes a spray adhesive that would work. I've used it to replace headliner fabric in cars. Cars that sit out in 100 degree temps all day and the headliner looked fine years later.

Foam board is waterproof.
Your good to go as is.
I was considering building a room out of that stuff as well.
I ended up w a tent city.

Hello,

Short version:
What solution would hold panda film best against Polyisocyanurate foam board insulation (aluminum facing)???

Long version:
I have finished insulating my groom... plywood walls -> spray foam for air seal -> fiberglass r-15 -> 6mil clear vapor barrier (all staples and seams are taped over) -> Polyisocyanurate foam board (radiant aluminum barrier on front back) -> panda wrap.

I am not looking for a debate of putting drywall, osb, plywood, etc. over the foam board and sticking the panda to that. In this situation without getting into to much detail it simply can't happen. Trust me.

I just simply need to know how I get the Panda film to stick to the insulation board with the radiant barrier aluminum facing and not peel off over time due to whatever (humidity, etc.)

Thank you all!
Try using square pieces of cardboard and staples. Easy to remove if needed.

I am growing in sub zero temps right now, put a lot of time into insulation. I have a couple cold spots, particularly the corners and around my intake that have condensation buildup. I used r-19 insulation and went over with 3/4 foam board. Prior to insulating I spray foamed every crack I could see. I never thought I would have this problem.

If the walls are cold you dont want warm panda on them.Air is your best insulation to stop heat.Hang the panda 1" away from the walls.Like curtains.This way no direct heat hits the cold walls.
