Showcase Hummer H1 Part 2: Sound Insulation and Anti-drumming

How to insulate a car floor and tunnel
Below you find a step-by-step guideline how to insulate the floor and tunel in a car. For this we used Vibraflex Extreme and Isomat FM, the insulating floor mat. The insulation and soundproofing of the floor also indicates the bulkhead, transmission tunnel, wheel arches of the vehicle. All the parts of the bodywork that are connected with floor or is part of the floor can be insulated in the same manner with the same products.

• Step 1
  Before insulating the floor of the car with sound insulating material, all of the surface of the bodywork should be thoroughly cleaned and degreased first. As for degreasing, you can use break cleaner, for example.
• Step 2
  Cut the Vibraflex bitumen anti-drumming plates to size before you heat them up, since cutting becomes more difficult when they are warm and supple. After cutting, place the plates at the desired places, in order to check if they fit.
• Step 3
  Heat up the Vibraflex sheets, as this makes them more flexible, for easy installation. This will also make the adhesive more responsive. You can use a hair dryer, but you can also lay the sheets on a heating radiator. Just above room temperature is fine.
• Step 4
  Remove the protection foil of the self-adhesive layer. Then, place the Vibraflex sheets on the surface you want to insulate. Press the sheets firmly in place, we advise to use our pressure roller, making sure no air remains between the surface and the sheets.
• Step 5 (optional)
  By placing Isomat FM you can enhance the sound insulation even more. This product contains a wear-resistant top layer, allowing it to be simultaneously used as a floor mat.
