In this study, engineering features of insolation materials produced from egg white, perlite, gypsum and fly ash were investigated. Density, water absorption ratios, ultrasonic velocities, thermal conductivities coeffecition of samples were investigated. Furthermore, linear absorption coefficients was measured by gamma ray saturation levels at 17.7, 26 and 60 keV energies. Thermal conductivity coefficient of the produced composites were found between 0.0882- 0.0995 Kcal/mh°C. Egg white decreases the linear absorption coefficients. Unit weight of the samples was found dependent on their contents. As gypsum rate increases, unit volume weights also increases.  As perlite rate increases thermal conductivity coefficions decreases. Egg white decreases the linear absorption coefficients decreases. The most important benefits of these type materials are being impermeable and exceedingly compatible with the environment. These lighter type materials had been compatible with Turkey and the Middle East environment. It has been hard-wearing against radiation. Hence, it is of high compatibility with the environment. The compressive and flexural strengths decreased with the use of egg whites in mortar. So, egg white enhance the binding property of samples. In most cases, some organic and/or inorganic additives are used as well to improve the physical and mechanical properties of mortar, such as egg whites and so on. Finally, this study shows that it is possible to produce insulation material resistant to sound and against radiation by using egg white, perlite and fly ash. It is seen that samples incorporating egg white could be used at hospitals, military and industrial facilities and shelters which are under radiation hazard. Furthermore, this insulation materials is going to be industrialized in Turkey after many experiments have been done on laboratory.
