The BIS Compact Door, patented folding-mechanism, uses little energy. Combined with the side tracks, a long life-cycle of operation is guaranteed. The lightweight, aluminium, sandwich door-panels are in a stucco design with integral stainless-steel hinges. They are CFC-free and give maximum thermal-insulation.
The robust door-framework is self-supporting and consists of hardwearing, abrasive-free rollers and tracks. Vision panels and wicket doors are possible options. The Compact Door requires a minimum level of steel-supporting construction. Cost savings are great compared to conventional overhead-doors. Because the door is very easy and quick to install, it does not interrupt any building-scheme and its unique folding style door-blade allows for optimal use of space in the building.
