SUN BLOCKING CALCULATOR

Size of Blind/Louver		Size of Lighttex

Welcome to the Lighttex Sun Blocking Calculator! We have developed the Sun Blocking Calculator to provide our clients and prospective clients with an exclusive and advanced daylight control planning tool. The Sun Blocking Calculator is extremely easy to use. Simply specify the orientation of the skylight or window, and the geographic location of the project, and click for results. The results are presented in grids showing a percentage comparison of direct sun blocking between vertical blinds, horizontal louvers and Lighttex by the daylight hour and the season of the year. The increased percentage of direct sun blocking equates to improved uniformity of diffused interior reflected light.

For your interest, we also provide data which compares the direct sun blocking performance of Lighttex dependant on cell size. The standard depth of Lighttex is 3”. By decreasing the width and height of the egg crate cells, additional direct sun blocking is possible.

The need for Lighttex is dramatically illustrated in those cases where the orientation of the window, the time of day, and certain seasons of the year would make the glare and heat gain from an open vertical or horizontal window covering intolerable. Lighttex outperforms in all cases.
