b17- DIY Noise & Heat Insulation for doors -
Since having both XUV & Safari in one garage, I was always bothered about High NVH from the Safari. There is night and day difference although both use the same 2.2 Block developed by AVL.
I thought I would be wise to try some DIY insulation and add to the royal feel.
Damping vs Insulation-
Damping means adding mass to the panel to change its resonant frequency. This is useful to minimize buzzing and vibration if you have High powered audio system.
Insulation means adding an absorbent/Spongy layer between the source and your cabin to Minimize transmission or Absorb the Sound. Sound Insulation also often works as Heat insulation.
Material Choice-
The material chosen was Neoprene. This is a closed cell foam with excellent Noise & Heat insulating properties. Does not absorb water like yoga mats. And Is very easy to work with.
Part 1 Cutting all the pieces to size-
2. Sticking the foam. I used Rubber adhesive like Fevicol SR or Speb 7.
The foam was Glued on the interior of Door pads, as well as Insides of doors. This will give me 2 layers of Excellent insulation. The Already Solid doors of Safari now close like a tank.
Every nook and cranny foamed up.
This is not a shop! Its how I placed weights to let the glue settle overnight-
Insulation glued on internal metal sheet-
