Vindur LTD. PVC Windows. Persiennes. Shutters.

Persiennes are elegant product for the complete styling of the windows in every home. With their qualities for additional heat and noise isolation and the opportunity to regulate the intensity of the light until 100 percent, they are indubitable asset of each window. When we use persiennes we reduce the noise with minimum 5 dB . At temperature + 40o C ordinary window cuts 79 percent from the outside heat. At temperature + 40 ordinary window excludes 21 percent from the outside heat. If we use blind the same window will exclude only 90 percent. Our research shows that during the winter when outside temperature is 10o C below zero, the temperature inside the room is, average + 10o C, and when we use persiennes the temperature is + 14o C.Held tests show that the blinds stands 14 000 cycles of opening and closing without noticeable ruin, which equates to nearly 40 years of normal exploitation.
