According to the DIN 5034-1 norm rooms should be protected from overheating with the use of external accessories (awning blind, roller blind) which give better protection than internal accessories.
FAKRO, to improve its products and increase the comfort of users, is constantly analyzing the effectiveness of protection from the heat using different shading devices. To this end, there have been prepared eight exactly the same research rooms, which are identically exposed to sunlight and equipped with the same roof windows. The study was performed with closed windows. The temperature was measured at several points, one meter above the floor. On the windows, there were mounted different accessories and the results of the research are presented in the chart.
