Window window treatments Heat Reducing Capacity

Window window coveringsvertical or horizontal slat-typeare more effective at reducing summer heat gain than winter heat loss.Because of the numerous openings between the slats, it’s difficult to control heat loss through interior window window treatments, but the slats offer flexibility in the summer. Unlike shades, you can adjust the slats to control light and ventilation. For example, when completely closed and lowered on a sunny window, highly reflective window coverings can reduce heat gain by around 45%. They can also be adjusted to block and reflect direct sunlight onto a light-colored ceiling. A light-colored ceiling will diffuse the light without much heat or glare.
