Have a few metres of
raammat left over and some foam sheets, the opening day of the new year 2011 was a perfect day to complete my sound proofing on my Elantra. I dont know about other owners but my Elantra roof is really noisy...rain drops even the tiny one's can be heard very clearly.
Side door trims, all hand handles, roof lamps, sun shades and rear/ front plastic pillar covers are removed. Front seat head rest was also removed.
Once the roof was brought down it exposed the naked truth...the roof was almost naked. With only 3 piece of factory cloth sound proof, its clearly not able to absorb all the noise.
Once the factory sound proof is removed, workers still have to removed those stubborn cloth that still stick on the roof.
The whole surface was thoroughly clean before the raammat was applied. Using a roller helps to pressed the raammat firmly.
Every inches of the roof was covered and I further added another layer of raammat to make it 2 layer of raammat on the roof.
The final touch was to install a single layer of 6mm self-adhesive foam sheet that act as sound suppression on the raammat. So the roof has both sound suppression and sound dampening.
Once completed, its time to fixed back the roof. The work hours to complete this was task was 3 hours.
