Bifold doors are generally very low maintenance. They will only need infrequent cleaning and occasionally you may need to oil the track mechanism to ensure smooth opening. Speak to your installer and ask about general housekeeping and long lasting treatments.
Isle Of Coll
Coll is an island located west of the Isle of Mull in the Inner Hebrides of Scotland. Coll is known for its sandy beaches, which rise to create big dune, for its corncrakes, as well as for Breacachadh Castle. It is in the council area of Argyll and Bute. Coll is about 13 miles (20 kilometres) long by 3 miles (5 km) wide and has a population of around 150. Coll's sandy beaches rise to develop big dune. The highest point on Coll is Ben Hogh in the mid west of the island, a ridge with 2 tops running NW/SE, which increases originally to an elevation of 104 metres (341 ft) with a triangulation pillar, and to 106 metres (348 feet) 450 metres (492 yd) to the southeast. In the 2011 census, the island's population was recorded as 195, standing for an increase over the previous years of almost 19%.
