| You need to create an air gap between the heat mat and the glass of the viv, i believe a thin piece of polystyrene can be used, i am sure there are other things that can be used as well. |

I wouldn't put polystyrene between the glass and the heatmat, the heat wont go through the 'styrene properly.
There are some brands of mat that need an airgap. (can't remember what they are offhand, Sorry)
Most mats should be able to go directly against the glass, providing it has a stat attached, it shouldn't crack the glass. Unless the glass goes into extreme cold quickly.
Likewise, I say it shouldn't, because I've NEVER known a stat controlled mat to crack glass. |

Ours cracked the glass - I can't remember what brand of heat mat it is (I'm at work) but we had it set up with polystyrene under the heat mat, then the heat mat then the viv. There wasn't an air gap between mat and viv so maybe that's the problem! I'm going to look at that as soon as I get home! |

Is yours on a stat , I have a mat under one of mine , touching the glass . It just never seems to reach a temp hot enough to crack it . |

| Mine is directly on the glass as per the instructions that came with it. It is an Exo Terra Desert Heatwave Mat which is designed for use with glass terrariums. It is also on a stat however and agree that it doesn't feel hot enough to crack glass. |

| The only thing I have found is that the Heatmat has to be bigger than if it was inside a wooden viv, otherwise it does not get the inside hot enough. |

if you're setting up a new glass viv then turn the stat on a little way for 24hours, then up a bit more for another 24 hours then up to around the desired temperature, so there's a gradual build up of heat instead of the mat being on full power and heating up really quickly - which cracks the glass!
DO read the manufacturers instructions (although disregard any that say put the mat on the side of the tank for snakes!!) as airflow is ESSENTIAL with some brands of mats such as Exo-Terra Heatwave, which conveniently come with little feet to raise the bottom of the viv to allow the airflow |

Yes its on a stat and I've a digital thermometer - hot end gets to about 29c at its hottest. In fact I've changed the stat on the glass viv as I wasn't convinced it was doing its job properly! |
