The BOW system uses readily available lightweight materials with strength equivalent to or more than the conventional ones. These materials include 3x3-inch angular bars welded together and joined by round steel bars to form 3x6-inch channels that serve as columns and beams, which are easily and swiftly assembled to constitute the skeletal frame of the house. Concrete mix is then poured onto the channels and the flooring of the first and second floors , with rough finish for the first ceramic tiling and straight finish for the second for vinyl, thus eliminating the need for topping.
The now concrete framework is then clad with M2 panels. Soon the roof is installed on steel purlins and the gutter on Hardiflex Senepa fascia board.
The stairs and bathroom are done the conventional way, but for the partition, BOW system uses Hardiflex fiber cement boards, and for the ceiling Hardiflex Lite fiber cement board. These materials are durable, and almost low-maintenance-free, simple and quick to install, and resistant to damage, fire, termites, water and severe weather conditions, while providing heat insulation to the house.
The secret of the BOW system is in the fast, efficient, & economical construction of a light but very durable house from improvisation and right combination of materials that provide optimum value to the end-user at the least cost.
