In general uPVC is used for soffits and fascias as it is very strong and durable. It also requires very little maintenance. However, wood can be used and is still popular on listed properties as it retains the original material. Older and listed buildings may require more traditional materials to be used.
Dunbeath
Dunbeath is a town in south-east Caithness, Scotland on the A9 road. It was the birth place of Neil M. Gunn (1891-1973), writer of The Silver Darlings, Highland River etc., a lot of whose books are embeded in Dunbeath and also its Strath. Dunbeath has an extremely rich archaeological landscape, the website of various Iron Age brochs and a very early middle ages reclusive site (see Alex Morrison's archaeological study, "Dunbeath: A Cultural Landscape".) Of Dunbeath's landscape, Gunn created: "These small straths, like the Strath of Dunbeath, have this intimate elegance. In boyhood we learn more about every square yard of it. We encompass it physically and also our memories hold it. Birches, hazel trees for nutting, pools with trout as well as a periodically noticeable salmon, river-flats with the wind on the bracken and also going away rabbit scuts, a riches of wild blossom as well as little bird life, the soaring hawk, the unexpected roe, the old graveyard, ideas of the individual who as soon as lived far inland in straths and hollows, the past and the present kept in a minute of day-dream." ('My Little Britain', 1941.). There is a neighborhood museum/landscape analysis centre at the old town college.
