Is the R-value of a PVC ceiling better than 6.4 mm RhinoBoard?

I need data on PVC ceilings’ R-value and the advantages of PVC ceilings over RhinoBoard.

    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.
