Reflection series underbelly insulation

[Soldotnatom]

I recently had need to loosen the coroplast underbelly and did not find any insulation material other than the reflective Mylar type sheet. Is this the insulation referred to in other posts? I really don't consider that insulation so I was surprised this sheet and the coroplast are the only “insulating “ materials in my 2015 Reflection 303RLS. This explains why I experienced cold floors. What have others found in their units?

Yep, that's it.

Actually works pretty good at keeping the heat in. It's also what insulates the floors of your slide outs.

If you need actual insulation in the underbelly, you will need to step up to the Solitude or other higher end coaches.
