The study gathered and codified information on UV and heat radiant exposure, and advanced methods to provide protection against UV and heat radiation in the global environment, and controlling the microclimate in the premises, as well as to exploit opportunities for the use of metals and their oxides in the formation of protective, given their characteristics, as well as methods for obtaining ZnO and fabric treatment. Experiments were carried out in vacuum thermal evaporation process different thickness Zn coatings on cotton and cotton worsted fabric, and linen cloth, which is frequently used in textiles eco-environment formation. During the experiment comparing different material samples with different coating thickness on the radiation transmittance and surface micrography, which suggests that the vacuum thermal evaporation process can be obtained even 0.12 mm continuous smooth Zn coating on cotton fabric, by increasing the coating thickness to 0.21 mm penetrating radiation flux decreases by 35%. Of linen yarn applied Zn layer is a granular structure, the greater the film thickness, since Zn clusters become coarse, so that the coating into less stable. Since the issue in the physical method of ultra-thin metal coatings applied on textiles opposed to chemical treatments does not create environmental pollution, is to push research to improve the adhesion, as well as look for ways to give metal coating dirt repellent surface properties
