Abstract

The present work shows how insulation can be used for walls of new buildings. To reduce the amount of electricity used. The experiment was carried out in the winter at the Technical University of Engineering (Najaf city, latitude 32.5 north), Iraq. Using a test model of two similar sandwich panels. Two rooms (1.65 m long, 1.5 m wide and 1.5 m high ) facing south. The first wall was built of bricks (12cm) thick and covered with a layer of cement (Ficus) (1cm) thick. As for the second wall, the same as the first, but the second wall of the room is covered with alucobond  material in front of the built wall and contains air gaps that are between the wall and the covering layer. Due to the high absorbency of cement with low thermal conductivity of the packing materials used, there was a large discrepancy between the internal and external temperature of the non-covered wall and the insulated wall. We note that the use of alucobond panels in general does not reduce the value of the heat transfer coefficient as it remains above international standards, however, the presence of these panels alucobond reduces the heat load.
