Specifications

SECTION A

BASE PLATES

(Patent No 81/6187) The 1,6-mm galvanised and patented base plate used has been specially designed to ensure that the whole construction forms a unit with the foundation and floor slab.It is placed on the face brick foundations and fixed to the floor slab with concrete by means of foundation bolts and reinforced steel.

OUTER WALLS

The outer columns are bolted to the base plate. On the outside between every two columns a 9-mm fibre cement sheet is fixed with aluminium cover strips. The fibre cement sheets projec beyond the floor slab to the brick foundation to form a waterproof and dust-proof seal at the bottom. Aluminium cover strips between the fibre cement sheets are screwed to the columns. A further 0,60-mm stud is placed between the two steel columns and on the inside a 12,7-mm Gypsum Rhino board is screwed to all three columns to ensure maximum rigidity. The joints and screw-down tops are dressed with a gypsum material and smoothed to give an even finish. Together with the outer and inner panels, a 94-mm wall is formed which ensures maximum rigidity and insulation.

  • Fibre glass insulation 50-mm Aerolite glass fibre insulation is placed in the cavity between the two boards for increased insulation.
  • Face brick profile panels The face brick profile panels as per standard plans are included in the basic price. To further enhance the aesthetic appearance the outer fibre cement sheet can be replaced with face-brick profiles.

WINDOWS – ALUMINIUM WINDOWS

The windows are of a composite construction and are placed between the full-length columns on top of shorter columns where required. If a window takes up more than one column, a bearer beam is built in. This beam, together with the other columns, is bolted to the top rails. The windows vary in size and are available in sizes 1 to 3 modules wide and from 600-mm to 1,8-m high, provided with 3-mm or 4-mm glass, depending on the size..

ROOF CONSTRUCTION

Please note: One truss is placed on each module to ensure uninterrupted rigidity. The trusses are conventional wooden trusses incorporating suitable bracings and wooden laths according to Engineering Specifications. The pitched roof with roof pitch of 20° is clad in galvanised Iscor S-Rib Supraspan hardened corrugated iron sheets, 0,5-mm thick stretching from the roof ridge to the gutters, with no horizontal joints. The roof overhang is 600-mm.

  • Harvey tiles :A Harvey tiled roof, enhancing the appearance of your house can also be supplied. The Suppliers give a 30-year guarantee.
  • Sisalation : Sisalation can be fitted under the roof for extra insulation at an extra cost.

INNER WALLS

The inner walls of 12,7-mm Gypsum Rhino boards are screwed on either side of the steel framework – no cover strips are used. The joints between the boards are filled with gypsum material and carefully smoothened off. Standard Supawood wooden skirting boards screwed to the steel framework round off the inner walls at floor level.

CEILINGS

Standard 6-mm Rhino boards screwed to wooden cross laths by means of steel H-sections are provided to seal off joints between boards to give a smooth finish. Cornices round off the ceilings against the walls.

  • Fibre glass insulation :On top of the ceiling boards between the trusses 50-mm glass fibre blankets are laid to complete the insulation.

GUTTERS, DOWN PIPES AND FASCIAS

Square galvanised gutters and down pipes are supplied and they are fixed neatly and firmly to steel fascias on the truss ends. The gables are rounded off with steel fascias to give an uninterrupted and durable finish.
