Looking into a Cork Liner

Hello!

I am wanting to use 3/4″ cork as as liner for the teardrop. I have seen a picture (from this forum) and I like the looks a lot. It matches the okoume look a lot better than getting a fabric covered foam alternative.

looking at the R-value, it is about the same. the minicell foam that CLC offers has a R-value of 2.8 to 3.0. Cork is 2.55-3.1 for the same thickness for each item (3/4″).

What I am looking for is if anyone has used cork as a liner, and what thier experience with it has been. I am wondering how well it conforms to the trailer and what the heat retention is. I am not really worried (looking into it) about the internal humidity issue, cork seems to naturally do that on its own.

Thanks in advance for any advice!
