This depends on the amount of insulation already present in your property. However, adding insulation has been proven to improve the energy efficiency of your home and decrease your heating bills, this is more obvious in older properties or where single glazing is still in situ.
Berriedale
Berriedale is a small estate village on the north eastern coastline of Caithness, Scotland, on the A9 roadway in between Helmsdale and Lybster, near to the border in between Caithness and Sutherland. It is protected from the North Sea. The village has a parish church in the Church of Scotland. Simply south of Berriedale, en route to the north, the A9 passes the Berriedale Braes, a high drop in the landscape (brae is a Scots word for hill, a borrowing of the Scottish Gaelic bràighe). The roadway falls considerably (13% over 1,3 km) to connect a river, before increasing once more (13% over 1,3 km), with a variety of sharp bends in the road-- although some of the hairpin flexes and also various other close-by slopes have actually been relieved in recent times. The impracticality (and also price) of connecting the Berriedale Braes stopped the building of the Inverness-Wick Far North Line along the east shore of Caithness; instead the train runs inland via the Flow Country. Berriedale is located at the end of the eighth stage of the seaside John o' Groats Trail.
