| Abstract | ||
| The determination of the best (economical) types from many types of suggestive ceiling insteads of common concrete, (high thermal conductivity & heavy, it's consumed large quantities of raw materials and it's have also much built time) which it is used in Iraqi construction roofs, is explained, in regard to the recommendation based of the criteria of maximum reduction in total cost. Sixteen roofs were also included in the study, which was carried out at Baghdad city (latitude 33.2N) it is assumed that the air-conditioning process is performed by electricity . The researchers found that , the most economical roof is concrete with 25mm & 50mm thermal insulating materials, but it very heavy, while, longitudinal concrete beams and hollow block concrete as a filling materials between beams have good reduction in total cost and also has decreased the built time and weight, while uncommon roof, sandwich panal have also good economics and very light and low builts time. | ||
