Ok so i am building all new cages for my snakes and bearded dragons I would like to put sliding glass doors in the front of the cage

?1 is 1/8 in standard glass ok to use / will it hold up to the heat and animal

?2 does the glass need to be completely trimmed

?3 will the hard plastic track work for sliding the glass

?4 what if I built my own track out of wood to match the cage what is the recommended depth

some more cage info
cages are built out of 3/4 in hardwood, I have two different sizes 6 ft cage (rough opening to fit glass into is 5ft long by 1 ft tall) 4ft cage (rough opening is 3ft long by 1ft tall) I can either place the glass in the rough opening our recess it behind the front frame. Heating is done by RHP, lighting LED waterproof strip lighting.
reptiles housed Boas, BP, and Bearded Dragons (they also have a built in UV light bar and a peg board top to account for the lack of moisture they need)
