Self explanatory, the time involved in bringing up to scratch any old timber fascia when you consider repairs and paint may give way to starting again wth a timber cover fascia (which has its limits) or removal of the timber fascia and replace with the RIGS system.
To date their hasn’t been a product to take care of such a huge range of building methods from using Rigs as a cover fascia for old timber fascia through to revamping the troublesome internal systems by converting to external and ALL fascia systems in-between.
