Double sided tape which will work in conservatory

[Kidsgrovemummy]

Just a quick one, trying to stick some lightweight foil to conservatory roof but don't want to use staples. Does anyone have any suggestions for tape or another way of fixing which doesn't need me to hammer nails or use staples? All the tapes I have bought fail under heat and my foil falls down :( Thank you

Stick on Velcro

Blu tack? I think that gets stickier in heat.

Tried gorilla and it is rubbish. Tried some extra strength tape from tool station and that just gave way. It's the heat element on the roof.

Paint it with pvc glue and stick it up? Keeping it up while it dries might be an issue, but I'd have though once dried it would stay.
