If it isn’t an option to replace existing windows with low-eLow-emissivity coating. Very thin metallic coating on glass or plastic window glazing that permits most of the sun’s short-wave (light) radiation to enter, while blocking up to 90% of the long-wave (heat) radiation. Low-e coatings boost a window’s R-value and reduce its U-factor. units to block excess solar heat, solar control films will do the job.

Unlike tinted films of the past, solar control films now have low-e coatings that reduce solar-heat gainIncrease in the amount of heat in a space, including heat transferred from outside (in the form of solar radiation) and heat generated within by people, lights, mechanical systems, and other sources. See heat loss. without noticeably affecting the view. Placed side-by-side, however, a coated window will appear slightly gray when compared to an uncoated one.
