Has anyone done something like in this below video to their hardtop on their JK/JKU to add insulation? With the honeycomb design of the fiberglass construction is this even possible to fill all off the voids with spray foam to add insulation.


Thank you in advance.

 

I guess you can. I wouldn’t. JMHO

 

Most of us purchase headliners, it will look 1000 times better, and adds insulation.

I recommend hothead headliners, but some also like Mopar and Boomats.
