Johan,
Neither RhinoBoard nor PVC ceiling panels have an appreciable R-value. These are not insulation products.
RhinoBoard is the brand name of a type of gypsum wallboard (plasterboard).
PVC ceiling tiles are like vinyl siding for your ceiling.
The R-value of either product is less than R-1. If you want your ceiling to be insulated, you will need to install some insulation -- for example, fiberglass, mineral wool, cellulose, expanded polystyrene, or polyisocyanurate.
