"I believe the laminated has better sound reduction."
I had not even considered that, but laminated would about have to have the edge. Glass and steel are your enemy when it somes to a quiet interiors. Just don't believe it if you're told you have to live with rattles and road noise becaue you don't.
And there is nothing really wrong with the Home Depot route (Peal and Seal), but you can get heat resistant sound deadeners for awful close to the same price.
