DIY HMMWV Upgrade – Installing Reflectix Roof Insulation in the Project Humvee Battlewagon

In this video desperation leads Jeff and R-man to get creative and find a way to keep the passenger area of the HMMWV warmer inside when it is cold outside.

More HMMWV articles can be found under the Humvee category menu above or by clicking HERE. You might also like the HMMWV section of our Amazon store where we have listed lots of replacement and upgrade parts for Humvees. We have also found a lot of HMMWV parts on eBay (link).

Tools and supplies used in this DIY project:

Assuming you already have a knife and scissors, this is about a $30 upgrade. However, you will have Reflectix left over that you can use for other projects.

Total project time

It took us about 45 minutes. I suspect we could have done it in 20-30 if we weren’t filming.

Project difficulty

I’m going to call this “Easy”. The only slightly challenging part might be cutting the slits for the velcro that secures the top to the center support bar without also cutting a hole in the top.

End result

I wasn’t sure whether this project would produce a noticeable result. However, I am thrilled to report that adding a single layer of insulation to the soft top of the HMMWV was very effective. So much so that I am thinking of adding a second layer. I mean, if one is good, then two must be twice as good… right?

All joking aside, the great thing about insulation is that it provides benefit no matter the weather. In the summer the Reflectix insulation will keep the passenger area of the Humvee cooler. We have already seen first hand that the insulation helps keep the heat in the cab of the HMMWV. I wish I had thought of this back when I had any of my soft top Jeeps. Suzuki Samurai, or even the hard top Jeep. Any one of those vehicles would have benefited from an extra layer of insulation. And the concern noted in the video was unwarranted. The Reflectix was not noisy… or at least I didn’t notice any extra noise from it.

Suggestions?

Please leave a comment if you have suggestions on how to better insulate the HMMWV.

The Project Humvee Battlewagon

Gear Report acquired a real HMMWV (High Mobility Multi Wheeled Vehicle) from the US Army for use as our official field and shooting range vehicle. We have already posted about some of our upgrade projects (Project Humvee Battlewagon article links) and have a lot of really cool projects on the way. Consider subscribing so you don’t miss any of the cool reviews as we post them.
