Economic study of thermal insulation in Egypt

الملخص EN

This paper studies the possibility of improving the thermal performance of buildings through using different types of thermal insulating materials and construction as insulating systems to conserve energy from envelope of residential and commercial building sectors in Egypt.

Different types of insulating materials have been investigated in the laboratories of Housing and Building Research Center to determine the important physical and mechanical properties of building materials, insulating materials and insulating systems.

In addition, a feasibility study has been carried out in the Egyptian markets to study the payback period of different types of thermal insulating materials.

The results of this investigation demonstrated that most of the local building materials in Egypt have a thermal resistance lower than that required for thermal resistance determined by the Egyptian code of energy.

These local building materials need to work with thermal insulating materials to achieve human comfort and conserve energy.

The main function of thermal insulation is keeping the mean radiant temperature of indoor surfaces constant.

This function reduces the energy consumption for heating and cooling loads in buildings.

Insulating materials such as refractive, cellar, flag and lightweight concrete are the best materials used in insulating systems through Egypt from north to south.
