Shower liner?

[Jeskie]

I have lined the inside of my enclosure and wanting to put the heat lamp inside the box. Will my mildew shower curtain catch fire or release toxins? I need help

not if you put substrate over it. i have used that method for about 8 years, the shower curtain liner is totally covered over with substrate...

ok. so i should cut it down? I have it the entire box lined to the top. its hard to see in the picture. i just have gaps in the bottom of my enclose i want to cover.
