DYI Reduce Road Noise & Improve Insulation With This Cheap & Effective MOD

Looking to reduce road noise and keep your cabin warmer. Here’s a cheap alternative to those expensive hardtop headliner insulation kits.

Cost me around $50 and my time.
  • $10 PolyShild half-inch foam board – Home Depot
  • $10 Fleece Blanket WalMart (on sale)
  • $10 3M 77 Spray Mount Adhesive WalMart
  • $5 Spray Mount / Rubber Cement Remover
  • $10 3M Heavy Duty Double Sided Tap

TIPS: I split the top panel in two, using the natural ridge as a divider.

If you have satellite radio, be sure to remove the Mylar where your antenna is. Mine is centered on top of my roll bar.

I installed the liner while my top was still hanging. May have been easier working on the the ground - but I didn't want to bring it down and them back up to install the top.

AFTER THOUGHTS: Because I have a roll bar speaker kit, the half-inch PolyShild foam board just makes the gap between the roof and the roll bar. So the hard top now rests on the sound bar. While the front clamps hold down the top as it did before the mod, the rear portion of the top floats a bit. When I tightened it down I noticed that my rear door just makes contact along the window rubber keeping the window closed. I haven’t had any air or water leaks; maybe quarter inch foam would have been a better choice – if available.

I think the pics show my progress.

Overall it really it looks great like a factory install.

It helped with the noise - radio sounds better - I can have a conversation with riders in the back. Also feels warmer.

Good luck ... Keep Jeeping On!

Nice job! Cheap, effective and looks good.

If I didn't keep my top outside during the 3 seasons, I would copy you. The bugs and small critters would love the fabric and foam and I would have to remake it every year.
