you can get damplifier which is better product for less.
now keep in mind there is a difference between how thick it is and how much weight it is. you want to mass load and add weight. raamat is cheaper but has 25% more airbubbles so less weight but thicker due to added air.
ALWAYS BUY BUTYL BASED NOT ASPHALT
