The thickest in the Super Liner range, the 12mm gives you the most thermal break and acoustic absorption of any closed-cell foam option in the Dodo lineup short of the Pro series. At 3sq.m per roll it's well suited to roofs and floors on larger truck and van builds — the areas where heat gain and road noise are hardest to control. Pairs naturally with DEADN Hex beneath and a fleece layer over the top.
