Sectional door experts
This week SDI went for training in Sectional door installation and repair at Indupart, based in Stockport. The sectional method of opening a door involves coiling metal rope. The product is clearly a different type of thing than the roller shutter, since this coiling metal rope works in concert with at least two large springs.
The sectional door has considerable advantages over the roller shutter: it has far better insulation properties; and the solid 600mm slats look better than the roller slats: they are not so confused and many. The downside is that this type of door does involve longer guide channels, often right overhead. The panels do not curl up into a small enclosure. It is therefore bigger and more obvious inside the building space.
