Hi

I cannot use hemp or wool insulation (for allergy reasons).  I am building a small trailer and am trying to decide between DuroSpan and Rigid Roxul as my insulation.

DuroSpan is a form of styrofoam which is said to be much less toxic than standard styrofoam insulation.

I would love to hear people’s experiences and opinions about these 2 types of insulation.

In particular, has anyone lived with Durospan in their walls for 3 or more months?

Thanks!
Phil
