Bison panel can be extensively used for the construction of modular houses for dwelling purpose. The board is used for dry wall construction as well as on underlay for roofs and they suit varying weather & terrain conditions. Thousands of shelters have been supplied to numerous organizations in the private and public sectors including Defense and Para military forces
Varieties of the houses include farm houses, dwelling houses, row houses, project houses, rest houses, guest houses, hill resorts, store sheds, penthouses, security cabins, mobile check posts, industrial sheds, shelters for disaster management, defense barracks, school buildings etc
NCL has adopted simple track and panel system for accurate alignment of walls required for the shelters. The ‘S'-shaped profile and ‘W’-shaped profiles are used for making the panel walls in single skin and double skin respectively. Same profiles are also used for the assembly of roof sheets in single skin and double skin. The wall panels are inserted in bottom track fixed on foundation with screws and self expanding plugs. The panel walls, 4 feet width, are inserted in 'W' profile & then aligned in the bottom track. Special panels are made to accommodate doors and windows. Another track channel is fixed on the top of the wall panels to make the walls stable. Separate light weight steel box sections are provided as vertical posts for fixing trusses over which roof underlay sheets or GCI sheets are fixed
The construction technique is simple. First, a thin channel section frame (Ground track) is fixed on a level base with screws and plugs. The track frame will be as per the plan configuration of the shelter. Bison panels fitted with steel profiles are then inserted in the track frame vertically by interlocking the joints of the panels to form a continuous panel wall
Specially designed posts are provided for the wall junctions and the corners. During erection, the wall panels are held in position by providing temporary props or supports. Upon completion of the wall panels, another channel frame (top track) is fixed on the top of the panel walls to keep the wall panels tight in position. The top track also helps to distribute the roof load uniformly on the wall panels. Special panels and ready fit frames are used for doors and windows
Light weight trusses and purlins are fixed on the top track with specially designed components. Roof sheets are then spread on the purlins duly interlocking the panels as was done in the case of wall panels. Roofs can be either gable type or pitched type. A roof coat is given to the panels to prevent leakages
The advantages of Bison shelters are many:
