Abstract

Iraq is belong one of three areas in the world, with the highest temperature in summer.But normal wall and roof constructions in Iraq are often without any thermal insulations.The aim of this paper is to calculate the thermal resistance and thermal transmittance of usual Iraqi wall construction. This calculations depends on the thermal conductivity ( λ ) of different materials .Those calculations were compared with insulated wall construction values.
As insulation material is a layer of expanded polystyrene (EPS) or extruded polystyrene (XPS) used in the calculations. The adding of this layer reduce the U-value for the construction to 0.431 W/m 2 .c 0
The result shows, That a wall construction consist of concrete hollow block-2chamber with 20mm external and 15mm internal plaster having U-value of 2.39 W/m 2 .c 0 .
This value is faraway from the U-value of ≤0.5 W/m 2 .c 0 as standard value by countries with extremely hot summer.
Keywords:
    thermal conductivity Thermal transmittance Thermal resistance Expanded polystyrene EPS XPS
