The Polystyrene foam is a thermoplastic material obtained by polymerisation of styrene. As a material, EPS is formed by union of so many beads of polystyrene produced during a modelling process with supply of heat as water steam until the following characteristics are obtained:
Nominal Density – 15k g/m2
Thermal conductivity – 0 .0 37W/mk
Steam resistance – 0.15mm Hg m2 dia/g cm
Type of Material – F self extinguishing
Compression stress @ 10% of strain = 50k pa.
Polystyrene is part of EPS regarded as a new technology in Nigeria, but not so in the developed world. It is a popular technology in places like UK, China, Italy used consistently for the last 40 years.
Citec ensures the doors, windows, kitchen cabinets, wardrobes, burglary proof materials are manufactured by the company to ensure that these products are churned out in a more mechanical way than pedestrian.
The cornices are unique. I’m happy that the house development committee in Abuja has imbibed the use of cornices. No carpenter can meet the standard requirement for cornice casting. It is done efficiently through a computer. By the time it is installed, one might think that it is just a photograph. It’s hard to detect that it’s the real substance. We expect that concrete cornices will be out of fashion in Nigeria. Cornices are cheaper, and don’t need too much technical work to install it.
A simple cornice may be formed just with a crown molding. The function of the projecting cornice of a building is to throw rainwater free of the building’s walls. In residential building practice, this function is handled by projecting gable ends, roof eaves, and gutters. Cornices don’t allow wind to blow away roofing sheets.
