Yes, but not only to keep it from sagging. When I made my first pair of panels using polyester batts, I didn't glue them to the plastic. When I made the second pair, I did. My feeling was that I got better performance at low frequencies from the second pair. That's a judgement based on what I heard since I have no way of doing measurements.
