While some old-style prism lights remain in use in many cities throughout the world (sidewalk lights, vault lights, store/transom lights, etc. Alternately, windows can simply be sited so as to avoid direct exposure (and thus large amounts of heat gain when using well insulated and weather-sealed windows) but to still provide light, but doing so still results in a somewhat lower thermal performance for the building. Draw on a normal where the ray enters the glass block 6. Take a measurement of the drop Then you need to take the supplied brackets and slide these between the rubber beading on your window and the glass.
