You are wrong to say there is no such thing
Huh?
I never said that?
What I said is that Ozone is O 3 - it's a gas - a type of Oxygen molecule. It exists, among other places, as a layer in our upper atmosphere. Most gasses settle to a specific layer of our atmosphere, and some - like hydrogen and helium gas - are so light they float right out of the atmosphere.
It's not some magical barrier or made of carbon or anything - it's just another layer of the atmosphere. Because of the nature of the molecules it consists of, it's one that is particularly good at blocking certain bands of solar radiation - one of the most significant health risks astronauts have to face (but we don't, because we have an atmosphere of many layers protecting us, see?)
ozone filters out the infra red rays
Well, no, actually, ozone is primarily known for its ability to block out ultraviolet rays (completely other end of the spectrum).
Here is a (decent) site regarding ozone and the ozone hole:

heat escaping through the ozone
Sorry, but no reputable scientist would ever suggest that. Or rather, would ever imply that 'escaping heat' is a bad thing that lack of ozone is responsible for. Excess heat bleeds off the Earth through all layers of the atmosphere and into space all the time. As a simplified example of this - why do you think it gets so cold on the 'night side' of the planet vs the 'day side'. Now, imagine if the heat acquired during the rotation through the 'day side' didn't bleed off and kept getting piled on from day to day.
I'm sure you can see that a little heat bleeding off into space is not a bad thing (and certainly not something any particular layer of the atmosphere is responsible for 'preventing')
I don't have any evidence that the space shuttle produces the cfcs that are responsible for the break down of the ozone molecules
1) It's not chlorofluorocarbons alone that are responsible for the ozone depletion
2) Do you know what CFCs are? The shuttle doesn't release any.
