The shoot through windows shouldn't cause you a problem, unless you are using an extremely sensitive mechanical head. With regular broadheads you will be fine. Only problem is the netting is not self-healing so do understand the arrow will damage it. My advise, set the blind up and shoot at a target through one of the windows.
I have heard though that the netting may catch fire if you shoot a rifle through them. Don't know if that is true or not, but something to be cognizant of.
