WINDOWS WITH FIREDCLAY SILLS, LINTELS, JAMBS AND LOUVRES
The three-storey building has a cast in situ concrete frame with a load-bearing outer leaf of locally made bricks, an inner leaf of blockwork, and a steel roof structure.
Bricks and clay products - tiles, ventilation grilles and decorative pieces - are a vital part of the indigenous vernacular architecture of Kampala. The local clay products have been developed and adapted by the architect for roof tiles, grilles, loadbearing walls, sills, lintels, jambs and shading louvres to windows.
The bricks were made to special sizes, with a plinth of larger 120mm 'rusticated' bricks at the base and thinner 55mm bricks above.
The window openings are lined with fired-clay surrounds, co-ordinated to align with brick courses. Sills were cast as single fired-clay units. Lintels and jambs/reveals were made up of two fired-clay units to avoid warping when fired, and fixed on site to the cast-in-situ concrete lintels and jambs.
Each window is shaded with a series of horizontal fired-clay louvres fixed to a projecting steel frame. The frame consists of a pair of 100 x 50mm T-shaped arms, each supporting a vertical 100mm steel at, with a series of 40 x 20mm RHSs - xed between them to support the louvres. The windows are reinforced with a steel frame to resist blast damage.
