Heat resistant backing for ceramic bulb holder

[Ulrimi]

I have recently installed a ceramic bulb holder onto the ceiling of a virarium (a tank for a reptile). The bulb holder holds an infra red heat bulb to provide a basking area for the lizard. The bulb holder is screwed directly onto the ceiling of the vivarium which is made of chipboard. The problem is that the chipboard gets very hot. Is there some sort of material I can put between the ceramic holder and the wooden ceiling that will not conduct heat and is not flammable?

The holder is a “Trixie Straight Pro Ceramic Socket” and the bulb is a “WUHOSTAM 150W Infrared Ceramic Heat Emitter No Light Terrarium Pet Reptile Heat Lamp”,
Both purchased from Amazon.

Thanks in advance

Damn! I just dumped 3 sheets of 3mm asbestos...would have been ideal!

Hi Ulrimi and Welcome to the Forum .
Neat - a lizard lamp !
Now please don't take Pirate too literally, but keeping it simple you might use a bit of tile backer sheeting - perhaps 6 or 12mm one

Berated, I am...and rightly so!
Composite sheet materials are good for this application though.
So many...too many to mention. Minerelle is one, almost any kitchen splashback composite sheet is good too...but not all.

Stick a bit of tin foil in

Mica is good, you can obtain this from fireplace and stove specialists for the transparent windows on stoves.

If area permits I'd screw a sheet of aluminium, 3 or 4 mm to the underside of the lid, that will help 2 fold, it will help by being a heatsink and spreading the heat over a large area and will reflect some of the heat downward. Make sure you get rid of all swarf if drilling it. Tinplate (think biscuit tin lid) might reflect better but won't dissipate the heat quite as well (but maybe adequate). Make sure there is no possibility of any electrical contact from the lampholder to any metal you use, put a thin piece of mica/kapton or other thin heatproof insulating material between the lampholder base and the metal.
