I have one ceiling pot light in my sauna and I noticed the electrician is using a plastic vapour barrier extension behind it. I feel this is wrong given it’s on the ceiling and it’s a few feet to the side of the electric heater. My concern is plastic melting and off gassing. What other type of backing for this pot light do you recommend? I’d like to show the electrician the alternative.
This is the location of the light to the heater, btw.
